What is the purpose of the inertial reel lock?

The purpose of the inertial reel lock is to prevent falling into the flight controls, ensuring that the pilot remains in a secure and controlled position during flight. The inertial reel is part of the seatbelt system, designed to retract and lock the seatbelt in the event of sudden movements or turbulence. This mechanism helps maintain the pilot's position relative to the flight controls, which is crucial for safe operation and quick reactions in emergencies. By securing the pilot in place, the inertial reel lock plays a vital role in maintaining effective control of the aircraft, minimizing the risk of the pilot unintentionally leaning forward or falling into the instrument panel during dynamic flight conditions.
