Good Point
Thanks guys,
keep 'em coming.
The point about having to change transponder to STBY whilst air taxiing in a single-pilot helicopter (I do powerline patrols in an MD500 too) is a good one and I hope any ATC personnel who may be reading this thread will understand how difficult it is to keep both hands and feet on the controls and reach down and change a frequency, rotate a knob, etc.
By the same token, however, one of the things I do is when on final approach to the runway/'H' and the aircraft is still stable with forward airspeed, I take a second to switch my transponder to standby before I start my hover and have to concentrate on air taxiing, watching for other traffic, being wary of my downwash whilst manouevering, etc. Unfortunately, that doesn't help when a frequency change is required after arrival and whilst air taxiing. That IS a handful.
We can all learn from each other... so please let 'em rip. This is great stuff!
