Controlled Rest Document Published on FSF Website

Research by Flight Safety Foundation on Napping

To be used as mitigation strategy, not as standard action

Not comply with Part 117, need to add CR 

Who is unaware of the value of a power nap? The recuperative powers of a “controlled rest” period can be attested to by any traveler, who is experiencing jet lag, by anyone who did not make it to Starbuck*s in time or who is attending a boring lecture after a long night. In this context, the Flight Safety Foundation has provided expert guidance on how pilots may used “controlled rest” to deal with this phenomenon when on duty.

After a long developmental process and equally prolonged promulgation process, the FAA issued a new Part 117. FSF seems to think that its research does not fit the new rules (note: the FAA rules on fatigue were issued before the new performance over prescription policy).

 

Some of the Part 117 history:

New Flightcrew Member Duty and Rest Requirements attract the same level of Controversy as the old Flight and Duty Time Regulations

A Pilot may not fly when Fatigued; that rule protects Safety

Post Part 117 implementation, should there be Wake Up Call for Airline Pilot Fatigue?

Union holds Seminar on Implementation of Part 117’s new Fatigue Regulatory Regime

 

Here is the Foundation’s explanation:

 

Flight Safety Foundation has published on its website a document by the industry’s Fatigue Countermeasures Working Group that details the best practices for implementation of a policy allowing for controlled rest (CR) on the flight deck.

CR is defined by ICAO as a “short sleep opportunity” that serves as a mitigation strategy in case of unexpected fatigue during flight operations. It is not to be used as a planned strategy to extend duty periods but rather as a “safety net” to combat in-flight fatigue.

Although the first CR procedures were introduced by airlines more than 20 years ago, the document, Controlled Rest on the Flight Deck: A resource for operators, provides the first review ever conducted of the practice of CR, along with an overview of current scientific research on napping, sleep inertia (the feeling of grogginess that sometimes occurs after waking) and CR. Other sections of the document

offer guidance for operators in deciding whether to introduce CR;

how to implement, document and review an effective CR procedure;

and

how to monitor and continuously improve CR as part of a fatigue risk management program.

An appendix contains the International Civil Aviation Organization’s recommended procedures for CR on the flight deck.

“For over 20 years, operators have been utilizing CR to harness the benefits of napping and limit the disadvantages of fatigue caused by extended hours of wakefulness, sleep loss and time of day,” the document says. “Sleep studies support the use of naps to improve alertness and performance, and operators that are experienced in CR are supportive of the use of CR.”

Some regulators, including the U.S. Federal Aviation Administration, prohibit CR, the document noted. It added, however, that “the absence of a CR procedure does not prevent flight crew from napping, let alone from inadvertently falling asleep” and that concerns about CR “can be managed through an effective CR procedure, crew training and integration” of CR into effective fatigue risk management.

The Fatigue Countermeasures Working Group is made up of fatigue safety managers from commercial air transport operators; representatives of pilot labor unions; and researchers and scientists from Clockwork Research, the National Aeronautics and Space Administration Ames Research Center, Washington State University, and independent research organizations specializing in fatigue and human performance.

Hopefully the FAA will find a means to reinterpret Part 117 or revise its language to incorporate the FSF findings on Controlled Rest.
