Wind effect corrections at high altitude

[Capt Groper]

Should an allowance be added to MORAs for strong winds in regions of high mountainous terrain?
For example Himalayas, where a MORA is 25,000' and 100kt wind = 25,000' + 1000' = corrected 26,000'.
Or do wind corrections only apply in approach terminal areas?

[Amadis of Gaul]

Don't be cheap, add 2,000'.

[Dave Clarke Fife]

I concur with Amadis of Gaul. This is my mobs suggestion.....


When the wind speed at the relevant MSA or SSA exceeds 50 kts, the MOA must be increased by at least 2,000 ft. When flying over mountainous terrain in mountain wave conditions a vertical clearance over the highest ridge at least equal to the height of the ridge above the surrounding terrain should be selected.
