What is the minimum IFR altitude?(including moca)?




in the ASA's 2014 Instrument Rating test PREP,


the book says that " ATC may use the "Cruise" to authorize flight at any altitude from "the minimum IFR altitude" up to and including the altitude specified.


If MOCA is also specified in the route being flown, "the minimum IFR altitude" is MOCA?


Or just, MEA equals "the minimum IFR altitude" ?

Flying at the MEA gives you obstacle clearance as well as Navigational signal. MOCA provides obstacle and Nav signal up to 22nm from the Navaid.

My FAA IFR knowledge is a bit rusty.*

Depends where you are (on or off an airway) and where you are going (does the airport have a published approach or not). The Pilot/Controller Glossary at the back of the AIM breaks it down pretty good

ah, the old cruise clearance


cherokee 2856D cleared to Cruise 9000' V6 Bozo airport.


minimum IFR altitude might even include minimum vectoring altitude if in radar contact.

the whole point is for YOU to choose the minimum available altitude from 9000' to the airport. You would have to ask for min vectoring altitude, or your charts would show on airway MEA or MOCA. or GRID MORA , or even the newer airway MORA.

which one is up to YOU, but YOU have to be sure which one is correct. So get out your chart

Plus since your example includes an airport you could add the initial approach altitude. I used to get a clearance from Maui to Kona at night after the towers closed, "Cleared to Kona airport via flight planned route. Cruise FL 200, squawk xxxx. Clearance void if not off by xxxx, contact Honolulu this freq after departure." At that time, we owned all the airspace from the ground to FL 200 along that route.
