[0002] Checking the launch system's compliance with the aircraft's power supply voltage and ignition signal specifications is a critical and urgent task during operational use.

The electrical docking vehicle, consisting of an electrical docking missile and a storage and transport launch box, matches the dimensions, weight, and center of gravity of a real aircraft.
