Title: Fixes Broken Airspeed Calibration

This fixes a bug introduced at some time between completion of testing on the airspeed calibration functionality and the 2.75 release that caused the airspeed calibration to be sent a zero value for airspeed. This resulted in the airspeed ratio going to the maximum value of 4 and staying there. This could cause the aircraft to fly significantly slower than intended and potentially stall.
