Mach-nr or IAS?
Hi folks,
Recently i was cleared to descend from FL340 down to FL240, with a restriction of flying 260 kts.
I asked if the 260 kts restriction was on conversion, but no, he wanted it right now! (from leaving FL340)
I was educated to fly Mach number on conversion in the climb.
I had numerous clearances to fly 260 IAS (or so) on conversion, but never to fly IAS above FL290, in my case descending from FL340.
Is this correct or just another german atc typical way of doing it their way......?
Thanks!
