What is the proper configuration for tail hook equipped aircraft?

• A. Energy Absorber, Pendant Cable, Net, Interconnect and Pretension Assembly
• B. Net, Interconnect, Pendant Cable, Energy Absorber
• C. Stanchion, Energy Absorber, Net, Pendant Cable
• D. Net, Stanchion, Energy Absorber, Pendant Cable, Interconnect and Pretension Assembly

Answer: (D)

The load path for tail-hook arresting gear relies on a complete capture frame that transfers the aircraft’s arresting impact into a controlled deceleration. The net provides the actual capture and containment of the tail hook, while the stanchion forms and supports the frame that holds the net in place. The pendant cable carries the load from the tail hook into the energy absorber, and the interconnect and pretension assembly organizes and preloads the components so the system stays properly aligned and taut before and during engagement. The energy absorber then dissipates the kinetic energy of the decelerating aircraft, limiting peak loads on the hook, aircraft, and deck. If any of these parts were missing, the system wouldn’t reliably transfer loads to a controlled energy-dissipation path. For example, without the stanchion there’s no sturdy frame; without the net the hook cannot be captured safely; without the pendant cable the load can’t reach the absorber; without the interconnect and pretension assembly the parts wouldn’t stay aligned or pre-tensed, leading to slack, misalignment, and improper engagement. This is why the full set—net, stanchion, energy absorber, pendant cable, and interconnect with pretension assembly—constitutes the proper configuration.
