This is an interesting subject as I am not sure that the ATC's are aware of these engine out procedures. Maybe someone from ATNS can comment. For example our company has a procedure to turn right at 5DME from JSV off 03 onto a heading of 090 and then to go through our clean-up procedure, speaking to ATC when we have time. If the ATC's don't know about it, it is going to come as a surprise, especially if the SID given was for a left hand turn out!
