Nick,
Fingers crossed here.....what kind of performance can we expect out of the S-92 for a ship pilot hoist op at +45 C day? Maintain Hover and depart OEI with 1.5 hours fuel aboard and 6 pax plus crew after an engine failure??? Is that how far technology has gotten us?
Is not the answer here....to build helicopters with sufficient power margins that allow reasonable performance on one engine to allow for specialized ops that are becoming more prevalent as time goes on....Pilot hoists, SAR hover recscues,high rise fire rescues (WTC type disasters?), mountain rescues?
