Steep or shallow ?
Paco
I would only do steep approaches if I was shure to stay in the laminar part, that means the approach is not too steep, to LS is not too far behind the ridge, basic wind is not too gusty...., because I do not want to end up at the wrong side of the demarcation line with a very steep descent, just before landing.
In the Mistral zone, the winds tends to be very gusty (typical 35 gusting 50), so for lesser ridges a shallow approach is the best in that case, provide you know a good path in depending on the other mountains around. That is at least what I do at my own LS.
Allow me to say that for anyone with not enough experience, be it flight technique or lack of local knowledge of the particular mountains and the local winds caution should be taken because unless it is a clean, isolated nice ridge, wind may not really be so predictable. Just saw a fire bomber (205) pilot come in at LFMQ (Le Castellet France) a few weeks ago with a very white face ... I am inclined to state that this was not because of lack of experience...
