i have asked a few coworkers - and they have never heard of that acronym
but if you look at it there are like 13 spaces for the acronym
but there are basically only like 10 required reports to ATC when IFR whats with the 3 extra spaces in the acronym then - thats what i dont get.
i came up with this and it KINDA works
M - Missed Approach has been executed
A - Altitude Change when operating VFR on top
R - ????? Duhhhhh ??????????
V - vacating any assigned altitude or flight level
E - entering holding (fix, time and altitude)
L - leaving a holding fix
O - Outer marker inbound when not in radar contact
U - unsafe weather/ flight conditions
S - safety of flight related issues
V - variation of true airspeed by more than 10 knots or 5% of the filed TAS
F - failure of any VOR ADF TACAN receiver
R - ????? Ummmmmm ??????
500 feet per minute climb or descent rate limitation
just havnt run into ANYONE who is familiar with this acronym (there are tons of them out there)
