Previously (fixed wing) it was possible to control the airspeed using cruise.FLT:
```
[SimVarForSpawningInTheAir.0]
IAS=30
```
Now (switching to SU11 helicopter) the aircraft will be spawned at a very high speed, around 100kt. Since mid-air start is often used near a POI, this sends the user off in the wrong direction at a good rate of speed. Can we reduce the speed which the helicopter spawns at?
