Ultra-Long-Range Flights

Hard ceilings: no flight duty period over 18 hours, and no flight with a scheduled flight time over 16 hours. Going beyond either needs a Fatigue Risk Management System.

Two absolute limits that sit above everything else:

  • No flight duty period over 18 hours (700.62(1)). This is the ceiling even with an augmented crew — 18 hours is also the highest value in the 700.60 table.
  • No flight with a scheduled flight time over 16 hours (700.62(2)).

Operating beyond either — an FDP over 18 hours, or a flight scheduled for more than 16 hours of flight time — would require a Fatigue Risk Management System (AC 700-047 §§ 4.68–4.69).

Interaction with split flight duty. AC 700-047 § 4.49 says an FDP extended by split flight duty has “no limit” of its own, while 700.62(1) states a flat 18-hour ceiling. The regulations don’t spell out how the two fit together — treat 18 hours as the ceiling and confirm against your Operations Manual.
