737 Landing climb
Right. This one's quite dull, so brace yourself:
What is the JAR OPS Landing Climb requirement for a perf A aeroplane?
JAR 1.510 has 2 Approach climb requirements - (That the a/c must be able to meet the missed approach climb gradient if it is larger than 2.5%, and a minimum MACG of 2.5% for approaches with a DH of >200'). These are for one engine inoperative.
The 'Appendix to 1.525' specifies a 3.2% Landing climb gradient (all engines, gear and flap in landing config). But I think this only applies to Perf B aeroplanes.
I can't find anything about the landing climb for Perf A, probably because I'm looking in the wrong place.
What am I getting at? Our performance dispatch for 737 classics (not certified under JAR) has a landing climb graph, with a fairly onerous penalty for a DH less than 200'. The 737NG landing climb graph (JAR certified) has no correction for low DHs, and I'm trying to get to the bottom of why. These are both Boeing graphs, by the way, and probably fairly standard for all operators.
Can anyone help?
