Getting the MOCA

And, if ATC is willing to provide the service, which includes radar
monitoring of your progress when assigned a Victor Airway below the MEA,
that is, of course legal.



Only if a MOCA applies and then only within 22 miles of a VOR. Radar
monitoring is not required.

Asked and answered previously.


§ 91.177 Minimum altitudes for IFR operations.
(a) Operation of aircraft at minimum altitudes. Except when necessary for
takeoff or landing, no person may operate an aircraft under IFR below-

(1) The applicable minimum altitudes prescribed in parts 95 and 97 of this
chapter; or

(2) If no applicable minimum altitude is prescribed in those parts-

(i) In the case of operations over an area designated as a mountainous area
in part 95, an altitude of 2,000 feet above the highest obstacle within a
horizontal distance of 4 nautical miles from the course to be flown; or

(ii) In any other case, an altitude of 1,000 feet above the highest obstacle
within a horizontal distance of 4 nautical miles from the course to be
flown.

However, if both a MEA and a MOCA are prescribed for a particular route or
route segment, a person may operate an aircraft below the MEA down to, but
not below, the MOCA, when within 22 nautical miles of the VOR concerned
(based on the pilot's reasonable estimate of that distance).

(b) Climb. Climb to a higher minimum IFR altitude shall begin immediately
after passing the point beyond which that minimum altitude applies, except
that when ground obstructions intervene, the point beyond which that higher
minimum altitude applies shall be crossed at or above the applicable MCA.




But, it isn't assignment of the Victor Airway because the Victor Airway
simply doesn't exist below its MEA (or MOCA beyond 22 miles) as a matter
of regulation.




That's not correct. Victor airways, unless otherwise specified, extend
upward from 1,200 feet to, but not including, 18,000 feet MSL.


That is not correct. Your confusing Part 71 with Part 95. Part 71
provides the Class E airspace for a Victor Airway. Part 95 provides the
minimum altitudes for a Victor Airway. They are not the same.
