IFR High Enroute Charts Flashcards
Where are Jet Routes found?
FL180 – FL450, inclusive.
What is MOCA?
Minimum Obstacle Clearance Altitude – provides obstacle clearance 1,000 ft above nonmountainous areas and 2,000 ft above mountainous. Also provides reception within 22nm of the station.
What is MEA?
Minimum Enroute Altitude – provides MOCA and guaranteed reception aid along the entire route.
What is an MEA Gap?
An MEA Gap may be found on a jet route where two VORs are slightly too far, reception may be lost for a small portion of the route.
What is MAA?
Maximum Authorized Altitude - this prevents an aircraft from picking up two crossing NAVAID signals on the same frequency.
Can aircraft fly above an MAA?
Yes, RNAV makes this possible as it is non-ground based.
