Flight attendants sometimes place their hands under their thighs during takeoff and landing because it is part of a brace position used during critical phases of flight.
The reason is not to “hold themselves down” or for comfort. The posture is intended to help in the unlikely event of an emergency landing by:
- Reducing loose body movement: Keeping the arms and hands tucked in can limit the chance of injury from limbs moving suddenly.
- Helping maintain a stable posture: A braced position keeps the body aligned and ready for impact forces.
- Protecting the hands and arms: Tucking the hands reduces exposure to impacts and keeps them from flailing.
During takeoff and landing, flight attendants also perform what is known as a silent review or silent safety check, where they mentally review emergency procedures, exits, equipment locations, and commands while seated.
The exact brace position can vary by airline and aircraft type, but it is generally designed around the same principle: protect the body and be prepared to respond quickly if something unexpected happens.
