Fellas...
Sorry for the earlier RANT on airspeed HOLD, it was trying to hold TRUE airspeed. This is set in the FSX Startup Menu setup. If you have trouble with this problem, Id suggest setting it up like I did. Under the SETTINGS/REALISM make sure the "Display Indicated Airspeed" is set instead of "Display True Airspeed".
I did this and SURE ENOUGH, the airspeed HOLD functioned just as it should.
