You settle into your airplane seat, ready for your 14-hour long-haul flight across the globe. As the plane levels off at cruising altitude, you peer into the cockpit and notice the pilots reclining their seats to take a nap. This sight might make some passengers uneasy – are pilots really allowed to sleep on the job while commanding a commercial airliner?
The answer is yes – in fact, it is required by aviation regulations in many cases. Pilots operating long duration flights must get inflight rest to ensure they stay alert and minimize fatigue. In this article, we’ll look at the specific flight time limits and rest rules for pilots, crew sleeping quarters, autopilot usage, and how airlines schedule flight crews to enable proper in-flight rest on long flights.
FAA Regulations on Pilot Flight Times and Rest Requirements
The FAA (Federal Aviation Administration) has stringent regulations on how many hours pilots can fly within a certain period, and minimum rest requirements before duty periods. These rules limit pilot fatigue and ensure alertness.
Some key FAA pilot flight time limits and required rest periods:
- 8 hours max – The maximum flight time allowed in one duty period is 8 hours for two pilots.
- 14 hours max – The total work period for two pilots cannot exceed 14 hours, including pre and post-flight duties.
- 10 hour minimum rest – Pilots must have at least 10 consecutive hours of rest between duty periods. This ensures adequate sleep opportunity.
For longer flights, additional relief pilots called augmenters are carried to rotate duties, as we’ll explain more below. But first, let’s look at the crew rest facilities that allow in-flight sleep.
Crew Rest Compartments Enable In-flight Sleep
All modern long-haul aircraft have specialized sleeping quarters for the crew called crew rest compartments. These compartments provide a quiet, darkened rest area with bunks and noise insulation to allow quality rest during flight.
Based on airplane type, crew rest facilities can accommodate 2-4 pilots plus cabin crew members. Bunks often feature curtains, adjustable lighting, and airflow controls. This allows multiple pilots to sleep in shifts or “hot bunk” (one rests while the other pilots). There are typically two entry doors to avoid disturbing someone sleeping.
By providing an area for protected sleep, crew rest compartments mean pilots can effectively rotate breaks and remain maximally alert in the cockpit without compromising safety.
Autopilot Use Allows Both Pilots to Rest
Another key aspect that makes in-flight rest possible is the advanced automation in modern airliners. The autopilot system can fully control the airplane for an entire flight, only requiring human monitoring.
This means at cruise altitude, both pilots can get periods of rest while autopilot handles the stable enroute cruising portion of the flight. One pilot will take first rest shift while the other monitors. Then they’ll swap off. This ensures at least one pilot capable of handling the controls is in the cockpit at all times.
Autopilot also alarms pilots if it needs attention for course adjustments or any abnormal conditions. This failsafe allows pilots to feel confident resting while automation flies the plane.
Careful Scheduling Rotates Pilots on Ultra Long Flights
For flights exceeding 14 hours, having just 2 pilots would exceed FAA limits. Thus, most airlines schedule one or more relief crews called augmenters to rotate duties on extra long segments.
For example, a 16-hour flight might have four pilots. Two primary pilots will takeoff and land the plane. But at the midpoint of the flight, the augmentation crew will briefly take over to give the original pilots their FAA mandated rest period.

Scheduling 3-4 pilot crews in this manner provides the necessary flight coverage and ensures all pilots stay within required flight times and get inflight rest periods without compromising safety.
On the longest routes like New York to Singapore that can exceed 18 hours, multiple crews might be carried to fully rotate duties. Detailed long range crew planning enables efficient inflight rest management.
Rest Assured, In-flight Pilot Rest is Normal and Highly Organized
While it may seem concerning to passengers to see pilots sleeping, rest assured it is completely normal and demonstrates strict adherence to aviation safety regulations.
Airlines don’t take chances with their flight crews. Rigorous scheduling provides for adequate rest through precrafted augmentation plans. Multiple pilots also mean someone is always actively monitoring the flight deck.
Modern aviation automation enables autopilot to handle cruising phases, allowing pilots to relax into brief recuperative rest periods.
And dedicated crew rest compartments allow quality sleep, ensuring pilots minimize fatigue and remain alert. Far from a sign of danger, scheduled inflight rest enables pilots to deliver passengers safely on even the very longest journeys.
So next time you spy the pilots sleeping on your long-haul flight, know that it is evidence of the aviation system working exactly as designed. Trust that while some pilots rest, the flight remains under the constant monitoring of their well-trained colleagues.
Inflight pilot sleep demonstrates strict adherence to fatigue science principles and keeps pilots operating at peak performance, ultimately enhancing airline safety. Their breaks mean your ability to arrive refreshed after crossing oceans or continents without even realizing your pilots briefly napped. Rest assured, inflight pilot rest is integral to smooth long distance flying.
