Thanks for your replies...
What I meant by adjusting FPA is that if the chart says -3.0 FPA, then that's what we must set...if you are late setting the FPA, you are stuck with -3.0
Other fleet types can adjust the -3.0 FPA up to a maximum of -3.5 FPA to account for a late setting of the FPA etc..
I can't see why you couldn't adjust the FPA, since you descend to MDA and no lower, it's not like you violate any IFR altitude(s).
Anyone care to comment on whether their company SOPs have them adjust the non-precision approach FPA to account for cold weather? We have a table to make an adjustment...
IMO, it just complicates an already busy procedure and you gain very little in making this adjustment. It's a non-precision approach , for goodness sake, and we treat it like a CATIII approach it trying to make it so precise....
Measure with a micometer and cut with an axe!
