Just like how cars have animated steering wheel, gear shifter and pedals, planes should have animated parts in their cockpit too.

That includes:
Throttle
Flaps
Rudder pedals
Yoke(or side stick)
Break
(future)landing gear

All of these things are currently possible right now, but are not implemented in OCP vehicles due to the fact they are older and simpler models. I would love to have them in the OCP vehicles, but detailed cockpits are not in the cards.
