What’s the definition of mountainous vs. non mountainous terrain?

[1lowsst]

How do they classify this.

All continental airspace west of the Rockies.

Look in the front of the jep binders, there is a pull out page

You can find the official FAA map in the AIM.

Look in the AIM. I remember seeing it in there once upon a time.

Look in the AIM. Chapter 5-6-5. Last page.

If I recall, it's those areas that provide a minimum of 2000' terrain clearance along airways.

Rockies and westward, and the Appalachain chain in the east.

It's the shaded areas on the pull-out jepp chart.

I think the question being asked is WHY is it mountainous. The best answer I've seen is an ICAO thing that says more then 3000 feet change in 10 miles (I think). As far as I've seen there is nothing FAA specific for it, although it may be in the TERPS somewhere.

ACK... first flight info post... and I'm actually answering a question

Jepp considers mountainous terrain as terrain that rises X amount of feet above the airport reference point (ARP) within Y miles. This is different from the AIM. Unfortunately I forgot what X and Y were. Sorry.

Except the central valley of California.

Does it matter?

Actually, as far as MEAs, MOCAs, and Grid MORAs are concerned, I think the Jepp Intro defines Mountainous terrain as an area thats elevation is more than 4000' msl.

Mountainous = Big Rock

NON-Mountainous = Little Rock

Both are hard and will kill you just the same. Good question though.

The official definition of mountanous areas is specified in FAR 95.
