Aha. Thanks so much! It never hit me that dumping fuel would be
related to a climb requirement.

Can you explain to a layperson how the climb requirement factors into
whether it is necessary to have a fuel dump function? Couldn't quite
understand the rule.


Sure. If the aircraft loses an engine immediately following takeoff, it
still needs to meet minimum climb performance standards so it can clear
whatever obstacles it may encounter near the the airport. It is conceivable
that if an airplane (particularly a twin engine aircraft) loses an engine,
it may need to reduce weight to meet climb standards. Dumping fuel is the
easiest way to quickly reduce weight...
