They sit on their hands during take off and landing so that if there is any turbulence they are already braced and ready for it. So, it's basically just for safety.

Flight attendants sit on their hands during takeoff and landing as part of a safety protocol known as the "Brace Position." By placing their hands palms-up under their thighs, keeping their feet flat on the floor, and tucking their chin, they create a rigid body posture that minimizes "flailing" and potential injury in the event of a sudden impact or emergency stop. This specific position keeps the arms secure and reduces the risk of broken bones or dislocations, ensuring the crew remains uninjured and ready to lead an evacuation if necessary. Additionally, this 60-second period is often used for a "Silent Review," where the attendant mentally rehearses emergency procedures, such as how to operate the door, where the nearest exits are, and what commands they would need to shout to passengers.

That’s an excellent observation! Flight attendants sitting with their hands tucked under their thighs during takeoff and landing is a deliberate safety procedure, not just a comfortable way to sit. Here are the key reasons why they do this:

1. The “Brace” Position for Themselves

During the most critical phases of flight (takeoff and landing), they assume their own version of a brace position. By sitting on their hands, they: Secure their own body: It prevents their arms from flailing uncontrollably in the event of a sudden impact or severe turbulence. Protect their spine: It helps maintain a stable, upright, and braced posture against the seatback.

2. To Be a Stable “Anchor” for Others

In an emergency evacuation, flight attendants are the leaders. They must be able to: Open heavy aircraft doors immediately, which requires significant strength and leverage. Assist passengers who might be panicked or injured. By bracing themselves securely, they ensure they are not injured themselves and are physically ready to perform these critical duties the moment the aircraft stops.

3. To Keep Hands and Arms from Being Injured

The cabin can be a chaotic place during a crash or hard landing. Tucking their hands under their thighs protects them from: Being crushed by shifting luggage from overhead bins. Being struck by debris or other objects flying through the cabin. Injury from their own limbs hitting hard surfaces.

4. Mental Readiness and Protocol

The position is a tactical and psychological cue. It signifies they are in “high-alert mode.” By assuming this standardized posture, they are mentally focusing on the procedures they must follow the second the plane comes to a stop. Their focus is entirely on listening, assessing, and preparing to command the evacuation if needed.
