52N in answer to your question, yes. I can think of many airports where the terrain would have a major impact on the Emergency Turn Procedure.
The point to remember though is that, atleast in my company there is not a standard procedure used wherever we are. Emergency Turns are in our performance manual and are specific for each airport and runway. So they should take into account any high ground around the airfield.
For example in Manch if were going off the 24s then there is no Emergency Turn, we can either follow the SID or fly straight ahead, (its up to us).
However if were going off the 6s then regardless of which SID we've been given in the clearance, if we have an engine fire/failure then we're going to follow the Emergency Turn, which in our case is the Listo Departure. We'll have that set up in the secondary flight plan so it can be activated quickly shoud we need it, (or atleast i do).
So I could imagine it being quite a shock to you guys when your expecting us to turn left, (on say a Nokin), and we go and hang a right.
Hope that helps
