Sure, it sounds like simple, but when i tried it i ran into number of problems.. with most annoying part being the AI pilot not able to lower the landing gear. I got the plane to just "touch" the ground with the airplane's tail at relatively low speed (120 km/h) but then without the landing gear extended, the AI pilot just pulled the airplane right back up again.
What i tried so far is:
shuttle action ["lower gear"]; shuttle is the name of the plane.
So, can anyone give me some hints? BTW, i used the same action command to lower the flaps and it worked fine.
