This is a beta version of the catapult, so I installed it on my old aircraft carrier. The operation methods of aircraft carriers and carrier based aircraft are here:

here we will separately explain the operation methods of catapults:
first, turn on AG2 and operate the roll and pitch, so that the front landing gear of the aircraft moves behind or above the catapult block (note that the aircraft direction should be roughly consistent with the catapult direction), then click the white button. After hearing a clang sound, the aircraft is fixed. Click the yellow button, and one second later, the aircraft will be ejected!

Then this is the link to the separate catapult
