Final answer:
The FA brace position is a safety position used by passengers in forward-facing seats during emergency situations in aircraft. It helps to minimize the likelihood of injury during impact or sudden deceleration.
Step-by-step explanation:
The FA brace position refers to the Forward-Facing Aft brace position commonly used in the aviation industry during emergency situations. This position is adopted by passengers sitting in forward-facing seats when facing the rear of the aircraft.
In the FA brace position, the passenger should bend forward with their upper body as far as possible, resting their head against the seat in front. Their feet should be flat on the floor, with their ankles placed together. The hands should be placed on top of the head, with the forearms protecting the face and neck.
This position helps to minimize the likelihood of injury during impact or sudden deceleration, and it helps to protect vital areas of the body such as the head and neck.
