I remember this problem happened looooooooong ago, maybe on PP5.0 planes. So, after playing a bit with the D.520 FM, the AI does not retract landing gear anymore on take off.

I remember something about too much fuel... nope, in my missions they have 300 lbs of fuel and the main tank is 106 gallons so it should be ok.

Please help!

Suggestions:

Make sure the DOF syntax is correct.

Make sure the wheels are defined in the parent aircraft prop list.

Check to see if theres too much fuel or too little fuel.

Make sure the engSFC value is set correctly.

Make sure the aircrafts engine is pointing to the correct fuel tank.

Check to see if the fuel tanks capacity is correct.

Check the waypoints in the mission.

If all else fails, I'll take a look at it for ya. I have a few missions where I know the AI WILL raise the gear if all is set correctly.

Thanks for the tips guys...

Hey Nat, that's interesting. Here is a short history of changes I did this weekend:


  • version 42: added more weight to the tail and rear fuselage. This fixes the AI breaking the propeller on landing, and improves FM. AI retracts gear OK.
  • version 43: fixed inner wing surface (was 48.7 sq.ft., set to 49.53 sq.ft. Also made MGs part of inner wings instead of wingtips, and placed them correctly. The AI does not retract gear anymore.

I'll try to move those airfoils, they're too close to the leading edge anyway.

Ok I moved the airfoils to better positions, and now the AI retracts the landing gear OK. However, the FM is affected a great way, so I got more and more testing to do. No big deal, it was far from correct anyway

Thanks a lot.
