RE:AIRSPEED during TAXI

[fstringham]

Before calibration of the Vx numbers in the D100 the airspeed tape would indicate a taxi/intial roll out on take off airspeed. Now the airspeed doesn't come alive until about 50 Knots......????????? Reset bottom of White to zero and still no joy......

Did you do a zero speed calibration (most people shouldn't be touching this)? If so, and you did it in not COMPLETELY still air, that could cause the issue. In that menu is an option to reset to the factory defaults. Other than that, setting the v-speeds doesn't change anything about the calibration. Give tech support a call to walk through some things if the zero airspeed wasn't it.

Also airspeed doesn't come alive until about 20 knots, which if you are in KMH would be about 50. Make sure your units of measure are still right.
