Victor2, are you telling me ATC does not trust pilots any more?
Wouldn't be a nice deal hand-fly in an airspace where you can not gain or loose one hundred ft?
As I recall, in my commercial pilot flight check ride I was allowed to gain (or loose) only 50 ft on level flight, and turns. And I had to be quick going back to the right altitude.
Wouldn't be nice to show computers that pilots can fly too?
Thanks!
