.... and even at sea level out of St. Thomas with the down wind take off.

The 2037's have plenty of temp margin. Most of the 2037 s are good for 43,750 lbs with the mods on the engine, but they don't choose to operate it that way. Seems like overkill to flip the packs off, but hey, the jet belongs to someone else. so I'll fly it the way they want it flown. If they've built a better hot and high airplane than the 757-200, I've yet to fly it.

The NTSB's recommendation to pull the engines for inspection for inspection with less than 10,000 hours on the wing probably has something to do with the conservative operation. The CF-34 on a 737 can stay on the jet for 30,000 hours (for comparison).

The early CF6's on the 767 are very tight on temperature margins on take off.

And the MD88's JT8D's just seem to suck under most conditions. It must have been a great engine in the 1950's.
