The Commander's Duty and the Fatigue Pressure
A first officer holds a European Union Part-FCL commercial pilot licence with a multi-engine instrument rating. He has 220 hours total time, of which 40 hours are on the aircraft type. His instrument rating is valid until the end of the month. He is rostered for a night flight from Vienna to Manchester, departing at 22:30 local and arriving at 01:10 local, with a return sector the same night. He has been on duty since 09:00 that morning, completing two short sectors and a simulator session. The commander notices that the first officer's logbook shows only 3 hours of night flying and no night take-offs or landings in the previous 90 days. The operator's operations manual requires both pilots to have completed three night take-offs and landings in the preceding 90 days before operating a night sector. The first officer insists he is current because his licence is valid.
1. Is the first officer's licence validity sufficient for him to operate the night sector? Identify the licensing and operator requirements.
Read the worked answer
No. Licence validity is necessary but not sufficient. Under the personnel licensing rules, a pilot must hold the appropriate licence and ratings, but the operator must also ensure that the pilot is current and qualified for the specific operation.
The first officer holds a valid CPL with a multi-engine instrument rating, so the basic licensing requirement is met for the aircraft and the instrument flight. However, the operator's operations manual imposes a recency requirement of three night take-offs and landings in the preceding 90 days. The logbook shows none in that period. The operator's requirement is binding on the flight because it forms part of the approved operations manual.
The commander must apply the more restrictive requirement. The first officer is not current for the night sector, regardless of his licence. The commander should not depart with him as operating crew unless the requirement is satisfied or the operator's manual provides a specific alleviation, which it does not on these facts.
2. The first officer has been on duty since 09:00 and completed a simulator session. How should the commander assess fatigue and flight time limitations?
Read the worked answer
The commander must assess both flight time limitations and fatigue. The first officer's duty period began at 09:00, and the night flight departs at 22:30 and returns after 01:10, so the duty period will extend well beyond 16 hours. That is likely to exceed the applicable flight duty period limit for the crew composition and the number of sectors.
The simulator session counts as duty under the applicable rules, and it adds to the cumulative fatigue. The commander should calculate the total flight duty period, the number of sectors, and the time of day. Night operations attract more restrictive limits because of circadian effects.
If the limits are exceeded, the flight cannot depart as rostered. The commander must either delay, replace the first officer, or cancel. The commander's authority to refuse to fly when unfit, and the operator's obligation not to pressure crew, are central. The first officer's insistence does not override the commander's assessment.
3. What should the commander do about the first officer's night recency and the simulator session before the flight?
Read the worked answer
The commander should first verify the logbook entries and the operator's recency requirement. If the first officer genuinely lacks three night take-offs and landings in 90 days, he cannot operate the night sector. The commander should notify the operator's crew scheduling and request a replacement or a delay.
The simulator session must be counted in the duty period. The commander should record the duty times and the reasons for any delay or cancellation. If the operator pressures the crew to depart, the commander should escalate the matter through the safety reporting system.
The commander should also consider whether he himself is fit for the return sector after the delay. The correct outcome is a delayed or cancelled flight, not a departure with a non-current and fatigued first officer. Safety reporting protects the commander from reprisal and ensures the operator addresses the rostering failure.
