'the air up there'
I agree with standards (but there were problems 20 years as well) and this thread is good as pruners are now diving into their books and having their 2c worth.
I seem to recall that the taxi call (CTAF) had to be made prior to the aircraft moving forward under its own power. Even just to reposition to a fuel bowser. Don't know if this is still true but an early call definitely can help you & others taxiing in your blind spot or choking up a taxiway / holding point.
'le Pingouin'
- look, I just thru that out there. I always say the maintaining alt. But wouldn't Approach know your assigned alt, any speed restrictions, waypoint time requirements etc? Doesn't all this stuff get forwarded down the line?
............And the aircraft has (most of the time) been 'identified' on radar!
