Hello RP:
This is from an Airbus manual, but since NADPs characteristics do not depend on aircraft type, I guess this might help:
I suppose your query is about a NADP 2 profile. Most airports I'm familiar with use NADP 1, but I've been to some (Vancouver, Canada, for example) that use NADP 2. At these NADP 2 airports, my last operator also wanted us keep TO thrust above thrust reduction altitude and, at about 3000ft, accelerate and clean up, setting climb thrust (and the packs!) after the first flap retraction. I take it that 3000ft is the "upper limit" as far as NADP profiles go, hence the 3000ft figure you lot are being handed by your company?
