ORCA lower than MEA?

Or are you saying that ATC would not grant the clearance because of radar
coverage/MIA/MVA issues?


We have lots of airways whose MEA's are well below the peaks of the
mountains, 4-5000 feet below. A lot of airways zig zag to get into the
low areas or passes between mountains. Some just go right over the top.
As for OTP we don't care about radar coverage. We use OTP everyday
here, more in the winter than the summer. We don't care what altitude
you go at. MVA/MIA is also irrelavant for OTP ops.

That's what I thought.

When you write about airways below the peaks -- obviously there are many of
those. But what I wondered, specifically, if there were MEA's lower than
the 91.177 minimum required IFR altitude (2,000' above the highest
obstruction within four miles of your flight path).

So far as the requiremnt (for pilots) for VFR altitudes, that would only
apply at 3000' or more AGL. So would probably not be applicable here.

You may not care, but that doesn't change the position of FAA
headquarters (note "minimum IFR altitudes in No 3).

From the AIM:

e. When operating in VFR conditions with an ATC authorization to
“maintain VFR-on-top/maintain VFR conditions” pilots on IFR flight plans
must:

1. Fly at the appropriate VFR altitude as prescribed in 14 CFR Section
91.159.

2. Comply with the VFR visibility and distance from cloud criteria in 14
CFR Section 91.155 (Basic VFR Weather Minimums).

3. Comply with instrument flight rules that are applicable to this
flight; i.e., minimum IFR altitudes, position reporting, radio
communications, course to be flown, adherence to ATC clearance, etc.
