So by 411A's description, you couldn't see 1.8 clicks on the meter on the downwind to base or it was a bust; is that right?
Yes, with the vast majority of FAA inspectors.
However, a few
might allow you to go to 2.0 DME (thus insuring remaining within the 2.3 mile radius), if they were in a good mood and the other maneuvers were up to snuff, accuracy-wise, however, the runway must
never be out of sight.
The circling maneuver is
supposed to be completed (for a type check) in an all engines operating configuration (3 or 4 engine airplane), however, some inspectors would fail an engine during (or just prior) to the circling maneuver, just to make you work a littler harder.
I have no idea what the twin engine guys do, as I don't fly a twin.
Why are op specs and some visability still reported in statue miles?
Because, that is the way it is done in the USA. However, as I fly outside the USA most of the time, I prefer meters (metres
