Goeff, I will bug the Chief Pilot again. I suspect it is French for something the Taunting Knight said to Arthur, "You are brave little people who wipe other people's asses..." (Python fans out there, anyone?)
R. Cal, you are right, when we adapted the original Turbomeca to the A+, we test pilots were aghast that someone would actually allow the OEI limit to vary by each degree of OAT and foot of altitude, and expect that the pilot would use a look-up table while wrestling with a failed engine! The folks who make the gages were able to work with us to produce a small computation that always showed "corrected" N1 so that the limit number shown was always a constant, thus you had to memorize one number and it was valid for any ambient.
I am always struck that those who like the single limit calculator for the latest Super Puma don't mention this vast shortfall on another EC product!
