Communication
 

To those pilots who are in work...

How much time to do spend - average? - talking to the ATCs during a flight?

I to do average 8.64 minutes.:ugh:

Yeah sounds about right ;)

Say on an average 2-3 hour flight, to spain or somewhere, talk to maybe 15 controllers, twice each, 10 secs per transmission. Factor in a few requests for mach number or change of level, say 3 per flight. That would total 33 transmissions totalling 5 mins 33 secs.

5 hour flight to Japan last night. From Clearance Delivery at origin all the way to parking at the destination was 17 frequency changes, and about 4 minutes of total talk time.

Miss one of those frequency changes or an altitude call and you will find out how important ATC and your employer think communication is. Yet we commonly use our flight numbers as callsigns. Many flight numbers are chosen for commercial purposes, with no consideration for on-air suitability. For example, one airline I flew with had something like 8332 and 8832 scheduled in the same area at the same time.
Sorry to be off topic a bit, but this nearly resulted in a collision, and I have difficulty in understanding why the asian_ company was not interested.
