ANDERSON, Circuit Judge:
Joseph Iervolino brought this action against his former employer, Delta Air Lines, Inc., alleging that Delta’s refusal to permit him to transfer to the position of flight engineer violated the Age Discrimination in Employment Act (“ADEA”), 29 U.S.C.A. §§ 621-634 (West 1985). On appeal from a judgment rendered on a jury verdict for Delta, Iervolino raises numerous challenges to the jury instructions, the denial of his motion for judgment notwithstanding the verdict (“JNOV”) or alternatively for a new trial, and the district court’s evidentiary rulings. We affirm.
I. BACKGROUND
In its commercial airline operation, Delta operates a variety of aircraft, including the Lockheed 1011. This aircraft requires three crew members in the cockpit: a captain, a first officer, and a second officer. The captain is the pilot and controls the aircraft. He is responsible for all phases of its operation. The first officer is the copilot and assists the captain. The second officer or flight engineer usually monitors a side-facing instrument panel, and does not operate the flight controls.
A regulation of the Federal Aviation Administration prohibits any person from serving as a pilot or first officer on a commercial flight “if that person has reached his 60th birthday.” 14 C.F.R. § 121.383(c) (1985). The FAA, however, has refused to establish a mandatory retirement age for flight engineers.
Delta employed Iervolino as a captain until his sixtieth birthday. In March 1980, five months before his retirement, Iervolino requested a transfer to the position of flight engineer so that he could continue his employment beyond age 60. Delta denied Iervolino’s request, and he was retired on his sixtieth birthday.
Iervolino filed this action against Delta in the United States District Court for the Northern District of Georgia, arguing that Delta’s refusal to permit him to transfer to a flight engineer position violated the ADEA. Delta defended its refusal to permit Iervolino to transfer to a flight engineer position on two grounds: (1) that its policy prohibiting captains from transferring to flight engineer positions (“two-step downbid”) qualified as a reasonable factor other than age (“RFOA”) within the meaning of 29 U.S.C.A. § 623(f)(1) (West 1985),1 and (2) that the under-age-60 qualification for the position of flight engineer is a bona fide occupational qualification (“BFOQ”) reasonably necessary to the safe transportation of passengers.2
[1412]*1412At trial, the parties offered conflicting evidence as to the existence of a policy prohibiting two-step downbids. Iervolino contended that, except for pilots approaching age 60, Delta had permitted pilots to bid for any vacancy and awarded the bids based on seniority. Between 1973 and 1984, there were 936 transfers from captain to copilot or from copilot to flight engineer by crew members under age 60 (“one-step downbid”). Iervolino presented evidence of two instances in which Delta had permitted a two-step downbid. In 1978, Delta permitted Ralph Sexton to transfer from captain to flight engineer as the result of a medical condition which precluded his continued service as a captain. When Delta acquired Northeast Air Lines, Inc. (“Northeast”) in 1972, two Northeast captains were also permitted to transfer to flight engineer positions at Delta.
Iervolino also introduced evidence suggesting that former captains serving as flight engineers would not present any “role reversal” problems. Iervolino pointed out that there have been no “role reversal” problems either when senior captains ride in a cockpit observer seat with more junior captains or when captains are given proficiency checks by senior check captains or FAA inspectors. Iervolino also claimed that Delta could evaluate a former captain’s ability to serve as a flight engineer on an individual basis since Delta already evaluates captains on their ability to manage their crew in all situations and observes how well crew members interact and coordinate their efforts.
Delta, on the other hand, introduced evidence that it has a long-standing policy prohibiting captains from bidding down to flight engineer positions. Delta asserts that this policy was based on the safety problems associated with two-step down-bids. Expert testimony indicated that when former captains serve as flight engineers, the roles of the crew members may become confused or ambiguous and former captains serving as flight engineers may intimidate other crew members during an emergency. Several pilots also testified as to the potential problems that could result from former captains serving as second officers. ’ Delta also argued that since an individual pilot may be entirely unaware of any difficulty in his transition to a flight engineer position until after a problem occurs, it is impossible to predict which former captains would have difficulty in making the transition.
With respect to the question of whether the under-age-60 rule is a BFOQ for the flight engineer position, Iervolino offered a variety of evidence to support his contention that a flight engineer’s normal duties are less critical to the safety of a flight than those of a captain or first officer. For example, the FAA has not extended the age-60 rule to the flight engineer position because the evidence indicates that flight engineers have rarely been a contributing cause or factor in commercial aircraft accidents and because flight engineers do not manipulate any flight controls. Iervolino also introduced evidence that 485 flight engineers over the age of 60, including 134 former captains, were serving on other commercial airlines. Finally, several former captains serving as flight engineers testified that they had experienced no difficulty in safely performing the flight engineer position.
Iervolino also offered evidence that it would be possible for Delta to evaluate its flight engineers on an individual basis for potentially disqualifying medical conditions. For example, Delta has relied on FAA-mandated medical examinations to assess, on an individual basis, the ability of pilots and flight engineers to perform their jobs safely and efficiently. Iervolino pointed out that Delta had permitted pilots to return to flight duty following the diagnosis of serious medically disqualifying conditions, provided these pilots could later pass medical examinations. Delta also has a system of proficiency checks designed to ascertain whether crew members can perform the required duties of the job safely and efficiently.
[1413]*1413Delta contended, however, that the age-60 requirement is a BFOQ for the flight engineer position. First, Delta offered evidence that the flight engineer position is essential to flight safety. Several pilots testified that a flight engineer’s failure to perform his duties properly could adversely affect flight safety, especially during emergencies. An aircraft simulator demonstration and various accident reports were also introduced to illustrate the importance of a flight engineer’s duties and the need for close coordination among cockpit crewmembers.
Delta also presented evidence that certain age-related diseases and infirmities (e.g., heart attacks, strokes, dementia, susceptibility to adverse drug reactions) become more prevalent at or around the age of 60, and that medical science cannot predict who will be susceptible to these diseases. Dr. John Rowe and Dr. Donald Kline concluded that there presently exists no reasonable method for Delta to evaluate its crew members on an individual basis.
After trial the jury returned a general verdict in favor of Delta, and the district court denied Iervolino’s motion for JNOV or alternatively for a new trial. The following appeal ensued.
II. ANALYSIS
On appeal, Iervolino challenges the jury instructions concerning Delta’s policy prohibiting two-step downbids and the BFOQ defense, the denial of his motion for JNOV or for a new trial, arid various evidentiary rulings. We consider each contention in turn.
A. Jury Instructions
Iervolino raises numerous challenges to the jury instructions concerning Delta’s policy prohibiting two-step down-bids and the BFOQ defense. On appeal, we examine “the challenged instructions ‘as part of the entire charge, in view of the allegations of the complaint, the evidence presented, and the arguments of counsel, to determine whether the jury was misled and whether the jury understood the issues.’ ” National Distillers & Chemical Corp. v. Brad’s Machine Products, Inc., 666 F.2d 492, 497 (11th Cir.1982) (quoting First Virginia Bankshares v. Benson, 559 F.2d 1307, 1316 (5th Cir.1977)); see also Western Air Lines v. Criswell, — U.S. —, 105 S.Ct. 2743, 2755, 86 L.Ed.2d 321 (1985) (reviewing jury instructions in the “ ‘context of the overall charge’ and the circumstances of the case,” including defendant’s closing argument) (quoting Cupp v. Naughten, 414 U.S. 141, 147, 94 S.Ct. 396, 400, 38 L.Ed.2d 368 (1973)).
1. Downbidding Policy
Iervolino raises three challenges to the jury instructions with respect to Delta’s policy prohibiting two-step downbids: (1) that the district court erroneously applied the test set forth in McDonnell Douglas v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973), to the instant case; (2) that the instructions improperly permitted Delta to defend this policy on the inconsistent grounds of the RFOA and BFOQ defenses; and (3) that the burden of disproving the RFOA defense was incorrectly placed on Iervolino rather than Delta. We find no merit in these contentions.
Iervolino’s first argument is that the McDonnell Douglas allocation of the burden of proof was inapplicable in the instant case because he presented direct evidence that Delta’s policy prohibiting two step downbids was discriminatory on its face. We reject this contention.
The only evidence that arguably constitutes direct evidence of age discrimination is a notation in Iervolino’s personnel file that the reason for his discharge was “Mandatory Retirement — AGE 60.” 3 [1414]*1414Plaintiffs Exh. 9. This statement, however, is ambiguous: it could mean either that Iervolino was forced to retire from Delta at age 60 or that Iervolino Was simply retired from his position as a captain but remained free to continue his employment with Delta in a non-flying position. Iervolino asserts that the record supports the former interpretation,4 and concludes that since he presented direct evidence of age discrimination, the jury should have been instructed that if it found this evidence to be credible, then the burden shifted to Delta to prove by a preponderance of the evidence that the same decision would have been reached even in the absence of age discrimination. We do not reach the question of whether the notation in Iervolino’s personnel file constituted sufficient direct evidence of age discrimination to require the giving of such an instruction because even if this notation were sufficient, Iervolino did not object to the instructions on this ground and the failure to give such an instruction in the instant case does not constitute plain error.
Rule 51 of the Federal Rules of Civil Procedure mandates that “[n]o party may assign as error the giving or the failure to give an instruction unless he objects thereto before the jury retires to consider its verdict, stating distinctly the matter to which he objects and the grounds of his objection.” Fed.R.Civ.P. 51. In the absence of such an objection, we will reverse only in exceptional cases where the error is “ ‘so fundamental as to result in a miscarriage of justice.’ ” Patton v. Archer, 590 F.2d 1319, 1322 (5th Cir.1979) (quoting Delancey v. Motichek Towing Service, Inc., 427 F.2d 897, 901 (5th Cir.1970));5 see also Hunt v. Liberty Lobby, 720 F.2d 631, 647 (11th Cir.1983); Barnett v. Housing Au[1415]*1415thority, 707 F.2d 1571, 1580 (11th Cir.1983).
Since Iervolino did not object to the instructions on the ground that the McDonnell Douglas analysis was inappropriate in the instant case,6 we review the instruction under the plain error standard and conclude that the district court did not commit plain error in instructing the jury on the McDonnell Douglas allocation of the burden of proof. We note that Iervolino’s proposed instructions were based on the McDonnell Douglas approach and did not request that the jury be instructed on the burden of proof in cases where the plaintiff presents direct evidence of discrimination.7 Moreover, when the court questioned Iervolino’s counsel about the appropriate allocation of the burden of proof on the RFOA defense, his counsel conceded that Delta had only the burden of production, not the burden of persuasion. See supra note 6.
Iervolino’s next contention is that the instructions improperly permitted Delta to defend its policy prohibiting two step downbids as both a RFOA and a BFOQ. Iervolino claims that these defenses cannot be asserted simultaneously with respect to the same policy since factors “other than age” by definition cannot constitute a practice where “age” is a BFOQ. We find no merit in this contention. While it is true that an employment practice cannot simultaneously be both a reasonable factor other than age and a bona fide occupational qualification, this does not mean that alternate theories cannot be submitted to the jury, i.e., that a particular practice is age neutral and that even if it were based on age, it is a bona fide occupational qualification. In the instant case, for example, Delta presented evidence that because of safety, it prohibited all captains, not only those who were approaching age 60, from down-bidding to flight engineer positions. If the jury accepted this evidence, then Delta’s policy would be a reasonable factor other than age. If, on the other hand, the jury concluded that Delta’s policy were age-based, then Delta would still be entitled to justify the policy as a BFOQ.
Iervolino’s third argument is that Delta should have the burden of persuasion [1416]*1416on the RFOA defense. This contention is without merit. We have repeatedly held that the plaintiff bears the burden of persuasion on the RFOA defense. See, e.g., Haring v. C.P.C. International Inc., 664 F.2d 1234, 1238 (5th Cir. Unit B 1981);8 Houser v. Sears Roebuck & Co., 627 F.2d 756, 757-58 (5th Cir. Unit A 1980).
2. BFOQ Defense
Iervolino challenges the BFOQ instruction on several grounds: (1) that the jury was erroneously instructed that the underage-60 qualification for the flight engineer position need only be “reasonably” related to safety; (2) that the instructions improperly fused the two-part BFOQ defense articulated in Western Air Lines v. Criswell, — U.S. —, 105 S.Ct. 2743, 86 L.Ed.2d 321 (1985), by permitting the jury to consider the need for safety in assessing whether age is a necessary proxy for the flight engineer position; (3) that the jury was precluded from considering the standards of other airlines and the FAA; and (4) that the instructions improperly allowed the jury to consider non-age factors in evaluating Delta’s BFOQ defense. These arguments, however, are without merit.
In Western Air Lines v. Criswell, — U.S. —, 105 S.Ct. 2743, 2751-53, 86 L.Ed.2d 321 (1985), the Supreme Court explicitly approved the two-part test for evaluating a BFOQ defense articulated in Usery v. Tamiami Trail Tours, Inc., 531 F.2d 224, 235-36 (5th Cir.1976). This test requires the employer to show (1) that the job qualifications are reasonably necessary to the essential operation of the business, and (2) that there is a factual basis for believing that all or substantially all of the persons within the class protected by the ADEA would be unable to perform the job safely and efficiently or that it is impossible or highly impractical to determine job fitness on an individualized basis. 105 S.Ct. at 2751-52. The Supreme Court specifically rejected the argument that the first prong is satisfied where the job qualifications are “reasonable” in light of the safety risks:
This proposal is plainly at odds with Congress’ decision, in adopting the ADEA, to subject such management decisions to a test of objective justification in a court of law. The BFOQ standard adopted in the statute is one of “reasonable necessity,” not reasonableness.
Id. at 2754.
Iervolino’s first objection is that the instructions incorrectly stated that the age-60 requirement need only be “reasonably” related to the safe transportation of passengers. Although the instructions at one point did improperly state that the job qualification must be “reasonable in light of considerations of safety,” Record on Appeal, vol. 25 at 2830, that improper instruction was both preceded and followed by the properly articulated reasonable necessity standard. The instructions began by charging that a BFOQ must be “reasonably necessary to the employer’s business,” then improperly mentioned reasonableness, but then continued to properly guide the jury in determining whether there was a “significant safety risk,” and if so, whether “all or substantially all of the persons excluded by the policy would be unable to perform safely,” or if not all or substantially all persons, whether “some persons excluded by its policy would be unable to perform safely ..., and ... it is impossible or highly impractical to determine on an individual basis which ones can safely perform, thereby justifying a general rule.” Id. at 2830-31. The BFOQ instructions concluded with a final statement of the proper reasonable necessity standard. Id. at 2832.
In closing argument, Iervolino’s counsel also stated the proper standard, id. at 2766-71, and Delta’s counsel did not contradict this statement. Moreover, a careful review of the charge conference reveals that the court and the attorneys for both [1417]*1417sides recognized that the proper standard was reasonable necessity, not mere reasonableness. It is apparent from the record that the district court intended to articulate the reasonable necessity standard. Id. vol. 24 at 2680-81. It is also significant that Iervolino did not specifically object to the use of the term “reasonable” in the only place that we find an improper use.9 Evaluating the charge as a whole and its articulation of the proper reasonable necessity standard, and in light of the lack of any specific objection and the proper articulation of the standard in the argument of counsel, we conclude that there has been no reversible error.
Iervolino’s next contention is that the jury instructions erroneously fused the two-step analysis of the BFOQ defense into “a single standard of almost complete deference to the employer’s decision.” Appellant’s Brief at 25. The first step is whether the job qualification is reasonably necessary to the safe transportation of passengers. The second step is whether there is a factual basis for believing that all or substantially all of the persons within the protected class would be unable to perform the job safely and efficiently or that it is impossible or highly impractical to determine job fitness on an individualized basis. Iervolino contends that the instructions in the instant case improperly permitted the jury to consider the need for safety in determining whether the second step had been satisfied in the instant case.
Since Iervolino did not object to the instructions on this ground at the charge conference, we review this instruction under the plain error standard, and we find no such error here. The instructions properly charged the second step, i.e., properly informed the jury of the two methods for establishing that age is a necessary proxy for the job qualification: (1) that all or substantially all of the individuals excluded by Delta’s policy would be unable to perform the job efficiently and safely, or (2) that it is highly impractical or impossible to determine which persons can perform the job safely. Iervolino asserts, however, that a subsequent reference in the instructions to the discretion that an employer has in establishing job qualifications in cases where there is a greater likelihood of harm improperly permitted the jury to consider the need for safety in assessing the second step, i.e., in determining whether age is a necessary proxy for the job qualifications. This contention is without merit. An examination of the instructions reveals that this passage refers to the first step of the BFOQ defense, i.e., whether the job qualifications are reasonably necessary to the safe transportation of passengers, not to the question of whether age is a necessary proxy for those qualifications.
Iervolino also objects that the instructions improperly precluded the jury from considering the standards of other airlines and the FAA:
The standard by which the reasonableness of Delta’s safety precautions is to be judged is not the standard of other bodies or other airlines.
Instead, its policy must be assessed against Delta’s own commitment to safety as demonstrated by what it actually does in the promotion of safety in comparable areas.
Id. at 2832. Since Iervolino did not object to this instruction, we review it only for plain error.
In Western Air Lines, the Supreme Court concluded that the standards of the FAA and other airlines are relevant to an airline’s BFOQ defense, but they are not to be accorded conclusive weight. 105 S.Ct. at 2754, 2756. Viewing the record as a whole, we are satisfied that the jury would have understood the relevance of the standards of other bodies in determining whether Delta’s policy was a BFOQ. First, the instructions specifically informed the jury [1418]*1418that the FAA did not have any regulation prohibiting the employment of second officers past age 60.10 Record on Appeal, vol. 25 at 2833. If the jury was not intended to consider the FAA position, it would have been unnecessary for the instructions to point out what its position was. Moreover, during closing argument, Iervolino repeatedly referred to the fact that the FAA and other airlines have not imposed the age-60 rule as a job qualification for the flight engineer position, id. at 2753, 2761-62, 2770, 2771, 2782, and Delta’s counsel also referred to the position of the FAA and other airlines, id. at 2808-09, 2813-14. We conclude that there is no plain error in this regard.
Finally, Iervolino objects that the jury instructions erroneously permitted the jury to consider non-age factors in determining whether its age 60 requirement for flight engineers was a BFOQ:
In assessing the bona fide occupational qualification defense asserted by Delta, you may consider more than simply individual plaintiff’s ability to perform the task of the second officer job.
You may also consider the effect that allowing the plaintiff or others [similarly] situated to serve as second officer would have on the safety of Delta’s operations because of its effect on crew command structure, crew communication, and crew concentration, or any other similar reasons relating to safety.
Id. at 2831-32. We need not decide whether the district court erred in giving this instruction because even if the consideration of non-age factors in determining whether a particular job qualification is a BFOQ were error,11 we conclude that this error is harmless in the instant case. The reasonable factor other than age issue was properly before the jury as an issue on which Iervolino had the burden of proof. It is harmless error to also put the issue to the jury in the BFOQ context on which Delta had the burden of proof.
B. The Denial of JNOV and a New Trial
Iervolino next contends that the district court erred in denying his motion for JNOV or for a new trial with respect to Delta’s RFOA and BFOQ defenses. These contentions, however, are without merit.
The appropriate standard of review for the denial of a motion for JNOV is whether, considering the evidence in the light most favorable to the non-moving party, [1419]*1419the evidence so strongly points in favor of one party that reasonable men could not reach a contrary verdict. See, e.g., Warren v. Ford Motor Credit Co., 693 F.2d 1373, 1374-75 (11th Cir.1982); Boeing v. Shipman, 411 F.2d 365, 374-75 (5th Cir.1969) (en banc). We review the denial of a new trial under a different standard. The denial of a new trial is proper when, after weighing the evidence, the trial court cannot find that the verdict is contrary to the great weight of the evidence. See, e.g., Jackson v. Magnolia Brokerage Co., 742 F.2d 1305, 1307 (11th Cir.1984), cert. denied, — U.S. —, 105 S.Ct. 2704, 86 L.Ed.2d 720 (1985). On appeal, we will reverse the trial court’s denial of a new trial only for abuse of discretion. See, e.g., Rabun v. Kimberly-Clark Corp., 678 F.2d 1053, 1060 (11th Cir.1982).
We conclude that the district court’s denial of JNOV was proper in the instant case. Turning to the RFOA defense, we find that there is substantial evidence to support this defense. For example, Delta presented evidence that it refuses to allow any captain, regardless of age, to downbid to the flight engineer position. See, e.g., Record on Appeal, vol. 16 at 866-67, 870-71, vol. 20 at 1893-94; Defendant’s Exh. 21. Delta justified this policy on the ground that a former captain serving as a flight engineer would create role reversal problems. See, e.g., Record on Appeal, vol. 15 at 731-33, vol. 17 at 1235-41, vol. 20 at 1830-33, vol. 21 at 2132-36, vol. 22 at 2242-44. Although Iervolino offered a variety of evidence to show that Delta did not have such a policy, the resolution of disputed facts is properly the role of the jury.
We also conclude that the BFOQ defense was amply supported by the record. With respect to the first prong of this defense (whether the age-60 rule is reasonably necessary to the safe transportation of passengers), Delta introduced ample evidence, including accident reports and the testimony of pilots, to show that the improper performance of a flight engineer's duties could adversely affect flight safety, especially during emergencies. See, e.g., id. vol. 16 at 974-81, 988-92, vol. 19 at 1713-22, vol. 21 at 2130, vol. 22 at 2170-71, 2240-41. There was also ample evidence in the record to establish the second prong of the BFOQ defense (either that all or substantially all individuals in the excluded group could not safely and efficiently perform the job or that it would be impossible or highly impractical to predict which individuals would be unable to perform the job). For example, Delta presented expert testimony that certain age-related diseases become more prevalent at the age of 60 and that medical science is presently unable to predict which individuals will be affected by these diseases. See id. vol. 17 at 1025-43, vol. 18 at 1331-39. Thus, we find that the district court’s denial of JNOV with respect to Delta’s RFOA and BFOQ defenses was proper.
We also find no merit in Iervolino’s contention that the denial of a new trial constituted an abuse of discretion. As described above, there was ample evidence to support both defenses, and we conclude that the district court did not abuse its discretion in finding that the jury verdict was not contrary to the great weight of the evidence.
C. Other Contentions
Finally, Iervolino challenges the district court’s refusal to instruct the jury on his disparate impact claim and numerous evidentiary rulings. We reject these contentions.
Iervolino first contends that the district court improperly refused to instruct the jury on the disparate impact theory. He concedes that the disparate impact theory was not expressly listed as a theory of liability in the pretrial order, but claims that the references in the pretrial order and its attachments to subsections 623(a)(1) and 623(a)(2) of the ADEA, the EEOC regulations and case law involving, inter alia, a disparate impact claim put Delta on notice that he would present a disparate impact claim.
[1420]*1420We will not reverse a decision of the trial court enforcing a pretrial order absent an abuse of discretion, see, e.g., Woods v. Burlington N.R.R. Co., 768 F.2d 1287, 1291 (11th Cir.1985), cert. granted on other grounds, — U.S. —, 106 S.Ct. 1456, 89 L.Ed.2d 714 (1986); Lloyd v. Professional Realty Services, Inc., 734 F.2d 1428, 1432 n. 12 (11th Cir.1984), cert. denied, — U.S. —, 105 S.Ct. 908, 83 L.Ed.2d 922 (1985), and we find no abuse of discretion in the instant case. At the pretrial conference, the district court repeatedly warned the parties that they would be held to the theories of liability designated in the pretrial order, Record on Appeal, vol. 11 at 129-30, 133-34, and Iervolino even filed a supplement to the pretrial order to include additional claims for relief, id. vol. 6 at 1539-40. Thus, Iervolino was put on notice that any legal theories not included in the pretrial order would be waived.
We also find that the references in the pretrial order, id. vol. 3 at 1432-39, were insufficient to give notice to either Delta or the court that Iervolino would rely upon a disparate impact theory. Subsections 623(a)(1) and 623(a)(2) of the ADEA do not refer to the disparate impact method of proof, and the pretrial order simply referred in general terms to the EEOC regulations on age discrimination. The case listed in the order, Monroe v. United Air Lines, 31 Empl.Prac.Dec. (CCH) ¶ 33, 330 (N.D.Ill.1983), rev’d, 736 F.2d 394 (7th Cir.1984), did involve a disparate impact jury instruction, but this instruction was simply one of several issues in the case. Since Iervolino was on notice that its legal theories had to be included in the pretrial order, and since it did not comply with this requirement, the district court did not abuse its discretion by refusing to charge the jury on the disparate impact claim.12
Iervolino also argues that the district court abused its discretion in several evidentiary rulings, but only three of these rulings warrant discussion. The admissibility of evidence is committed to the sound discretion of the district court, and even if error is found, the party asserting the error must show that substantial rights were adversely affected. See, e.g., Perry v. State Farm Fire & Casualty Co., 734 F.2d 1441, 1446 (11th Cir.1984).
First, Iervolino contends that the district court erred in excluding the identities of the commercial airlines that have permitted flight engineers, including former captains, to serve after age sixty. Iervolino claims that this evidence was probative on the question of whether the age sixty requirement was a BFOQ for the flight engineer position. We agree that the exclusion of the identities of the other airlines was probably error since this evidence would have clarified that the airlines which permitted individuals over age sixty to serve as flight engineers included large commercial carriers comparable to Delta and therefore would be relevant to the question of whether Delta’s age sixty requirement is a BFOQ for the flight engineer position. See Western Air Lines v. Criswell, — U.S. —, 105 S.Ct. 2743, 2748, 2754, 2756, 86 L.Ed.2d 321 (1985). However, we conclude that the exclusion of this evidence is not reversible error in the instant case. Iervolino was permitted to introduce the testimony of several flight engineers who had served past the age of sixty, see, e.g., Record on Appeal, vol. 12 at 84-105, vol. 15 at 623-710, and a document listing 485 persons who have served or are serving as flight engineers after reaching the age of sixty, Plaintiff’s Exh. 337. In his closing argument, Iervolino’s counsel also emphasized that this evidence showed that allowing former captains to serve as [1421]*1421flight engineers would not create any crew coordination problems and that age was not a necessary proxy for the flight engineer position. Record on Appeal, vol. 25 at 2761-62, 2771. Iervolino also introduced evidence and emphasized in his closing argument that the FAA had not extended the age sixty requirement for captains and first officers to flight engineers, see Plaintiff’s Exh. 317; Record on Appeal, vol. 25 at 2753, 2770-71, and the jury was instructed on the FAA’s position, Record on Appeal, vol. 25 at 2833. Thus, we are satisfied that the jury was aware that the industry as a whole had not imposed an age sixty requirement for flight engineers.
Iervolino’s next contention is that the district court abused its discretion in admitting evidence of the medical condition of Mr. A.B. Paul, another captain who had withdrawn as a plaintiff before the instant case went to trial. We reject this contention. Paul’s medical condition was relevant in the instant case since it illustrated the decrements which accompany the aging process. Under Fed.R.Evid. 403, the question of whether the probative value of evidence is substantially outweighed by the risk of unfair prejudice is committed to the broad discretion of the trial court, see Noel Shows, Inc. v. United States, 721 F.2d 327, 329 (11th Cir.1983), and we find no abuse of discretion in the instant case.
Iervolino also argues that the district court abused its discretion by permitting Delta to play the cockpit tape recording from Flight 1080. Iervolino claims that this evidence was inadmissible under Fed.R.Evid. 403 since the flight engineer did not play any role in the resolution of the emergency and the probative value of this evidence was therefore outweighed by the risk of unfair prejudice. However, we find no abuse of discretion in the admission of this tape. This tape illustrated the importance of crew coordination during an emergency, and revealed the supportive role of the flight engineer during an emergency. In fact, the flight engineer involved in the incident testified that he considered questioning the captain’s actions but decided to keep “[his] mouth closed.” Record on Appeal, vol. 22 at 2344-46. Thus, this tape and related testimony showed the potential problem that might arise if a former captain served as a flight engineer. The district court did not abuse its discretion in finding that the probative value of this tape was not substantially outweighed by the danger of unfair prejudice.
We have carefully considered Iervolino’s other challenges to the district court’s evidentiary rulings, but we conclude that they have no merit and warrant no further discussion.
III. CONCLUSION
For the foregoing reasons, the judgment of the district court is
AFFIRMED.
