I am flying the RW Designs Twin Otter and I am binding buttons to various Autopilot controls I use most. There is an IAS mode which is used for climb out, arm it and the aircraft climbs at the speed showing on the Airspeed indicator at the time pressed. I have managed to find the right functions for all the rest of my Autopilot buttons but I can't find IAS.
It's not:
Autopilot Airspeed sync
Autopilot Airspeed up
Autopilot Airspeed down
Autopilot Auto throttle speed toggle
G1000 Flight Level Change
Toggle knots/mach airspeed hold
Can anyone tell me if it's possible to bind this please?
