I've already got the RAM Air Turbine, realistic landing gear, and a custom made engine that I made (a first on my commercial airliners), along with the basic stuff like spoilers, thrust reversers, etc. Here is a list of items you guys can vote for in the comments to be included (you can include your ideas and vote for more than one item).
- Slats
- Taxi Engine (as found on my A310 and A330)
- Thrust Control for Eng. 1 and 2 (obviously both engines work on throttle, but if you hit a certain AG and yaw the plane the opposite engine will give more power, turning it faster)
- Pitot Tubes
- Collapsable Nose Gear (hit an AG, VTOL, and the nose gear will come up so you can like the real Gimli Glider did)
- Infinite Fuel (currently the fuel load gives the plane a very short flying time since it's so heavy)
