Altitude corrections windy conditions over mountainous terrain

[0074]

In my pervious companies in Scandinavia we used at set of corrections when flying over mountainous terrain in windy conditions:

< 30 kts 0 ft
31 - 40 kts 500 ft
41 - 50 kts 1000 ft
51 - 60 kts 1500 ft
Over 60 kts 2000 ft

I have tried to locate the origin of these corrections but until now without any luck - does any of you know where they are documented ?
I found another set of corrections reading the Doc 8168 but they are lower. Does the above include corrections or marging for mountainwaves or unstable air that the Doc 8168 corrections do not take in account ?

Which one is the correct correction to apply ?

The Doc 8168 corrections are:

Corrections for strong winds in mountanious areas :
20 kts : 53 ft
40 kts : 201 ft
60 kts : 455 ft
80 kts : 812 ft

What aircraft please and what were your usual cruising altitudes, did you apply these corrections to your actual altitude by flying that much higher? Were they corrections to your MSA?

Operate B737

Now operating in mountainous terrain with airport in 6000ft and MSA 160000 - approach starts at 11000ft

The earlier corrections were generel corrections in Europe over mountainous ares ei. Norway or the Italien/Austrian/French Alps. Altitutecorrections addet to MSA and Fix crossing altitudes.

Are they in your Part A?

[0074]

yes they were

Have you tried JAR/EU-OPS 1?

I have not I admit - the corrections have been there since I started flying B737 in 1986, so that is a few years before JAR
