I am ATPL student and dispatcher at a London airport. During the scorching hot period we had recently I was lucky enough to be working when the 37 deg record was broken.
I was dispatching a 737-400 with full load of pax (167Y) to Greece. I think weight of baggage was about 2000kg, fuel about 14,000kg. At the time OAT was 34 deg. When I collected flight docs and loadsheet from Flight Deck they were setting up the FMC. Noticed in the FMC the OAT was inserted as 34 deg celcius, assumed temp 38 deg celcius. So I guess they must have been pretty close to being performance limited, despite us having a 10,000ft runway.
Any 737-400 drivers able to comment?
