Putting out all the pax o2 masks is a good index(once on the 727 at LGA)..Be wise to talk to MTC,they can at least check for leaks etc. 'Heavy' a different Situ',one has to explain via the tech log if one exceeded the above stated criteria.If one touched down smoothly used full reverse-judicious brakes,and all the runway,this might relieve MTC from a 'full' oweight landing check(in some cases 25manhours).
