Depressurization Escape Routes

[michael707767]

With 12,000' terrain in a grid the Grid Mora alt would be 14,000. 2,000 above in mountainous terrain, 1,000' in all others is the way I believe it's set up. Of course I know you knew that anyway.

yep, thats what I worded it "Look at it this way, within a certain area on a chart there could be a 12,000 foot mountain. So the Grid MORA in that area would have to account for that." Never said what the Grid MORA would be....its irrelevant to the example. The point was there can be MEAs below the Grid MORA.

What does Continental use on their South American routes over the Andes?

Going to Lima from EWR the escape route from the spine of the Andes was an immediate turn to the west, toward the water and start down. Since the Andes are relatively narrow, it didn't take long to get away from them. We have (possibly had, I don't do it anymore) another one from BOG to UIO that has a decision point 95 miles from Girardot VOR. An engine loss/depressurization prior to or after that point had different procedures.

Going to/from DEL or BOM there is a similar decision point on A466 going through Afghanistan which is almost right on top of Kabul. Theoretically you can get down to 10,000 feet within 22 minutes. It works fine in the sim but if it happens in real life, you are having a bad day.

They are in the process of making custom enroute charts, which we already have for Alaska, that have a brown terrain Clearance (TC) MEA on them that allows you to go lower than the grid MORA as long as you are on the airway.
