It's Your Plane FS9, FS2004 and FSX Taxi and Air Speed Speech Recognition

The IYP application can adequately control the Taxi Speed of most aircraft and typically keep the ground speed just below 20 knots.

NOTE: You will see the IYP application sometimes tap the brakes in order to maintain the proper ground speed. Obviously, this wouldn’t let you win any extra credits from a flight instructor, but it was a technical necessity… sorry (:

The ground speed will drop quite quickly as you make a turn on the ground… the tighter the turn, the more the speed will decrease. Once you straighten out the direction, the speed will once again increase.

NOTE: If you are taxiing with a turboprop aircraft, please ensure that you have the fuel condition lever to low idle and/or decrease the prop pitch.

The IYP application can control the airspeed of most of the General Aviation (GA) type aircraft in the simulators. This is accomplished by saying, “Airspeed” followed by the desired speed. For example, in a Cessna C172 Skyhawk, you might say, “Airspeed One Zero Five." Your Co-Pilot will maintain this airspeed for you.

NOTE: Some aircraft respond differently than others based upon their power plant.

NOTE: You cannot specify an airspeed that exceeds the supported aircraft specifications.
