Definition
A cockpit-mounted handle that mechanically disconnects the landing gear from its normal actuating system, allowing the gear to fall and lock into the down position by gravity (and sometimes airflow) when the primary extension system has failed.
Plain English
A handle the pilot pulls to let the wheels drop down on their own when the normal system for lowering them isn't working.
Context Anchor
Seen in the emergency landing gear extension procedure for airplanes with retractable landing gear.
Why Pilots Care
It provides a last-resort way to extend the landing gear and avoid a gear-up landing that could damage the aircraft or injure occupants.
Intuition Check
Do not assume the emergency release handle repairs or powers the normal gear system. Its job is to release or activate the backup path so the gear can extend by the airplane’s emergency method.
Example Sentence 1
After the gear motor failed to respond, the pilot followed the checklist and pulled the emergency release handle to let the gear extend by gravity.
Example Sentence 2
The checklist called for the emergency release handle only after confirming that normal extension attempts had failed.
