What device is used to engage and absorb forward momentum during a routine or emergency landing or aborted takeoff?

• A. Jet Blast
• B. Aircraft Arresting Gear
• C. ILS Critical Area
• D. Informational Sign

Answer: (B)

The device is aircraft arresting gear. This safety system is designed to engage a hooked aircraft and absorb its forward momentum to bring it to a stop, either in an emergency situation or during an aborted takeoff. It works by having a cable stretched across the runway that is connected to energy absorbers; when an aircraft’s tailhook (or arresting hook) catches the cable, the cable’s energy is dissipated through hydraulic or other energy-absorbing mechanisms, rapidly slowing the aircraft while keeping it within a controlled area. This setup is used on some airfields and training environments to provide a reliable way to stop aircraft when normal braking isn’t sufficient or when a rapid deceleration is required. Jet blast refers to the high-velocity exhaust from engines, which is dangerous but not a mechanism for stopping an aircraft. ILS critical area is a safety zone around the instrument landing system and does not stop aircraft. Informational signs provide guidance and warnings but do not actively arrest or absorb momentum.
