Here at X-JET single engine landings require the use of flaps 22. Don’t know if eagle uses flap 22 landings on regular bases to save fuel (a much different picture than 45’s.) Also you have to add 18% to our available landing distance for a wet runway, plus 10% for single engine and times that all by 1.45% for flaps 22 (something like that.) That’s a total of 40% increase. Also flap 22 landings you float for days. Next time I fly Ill do the calculation “guessing their weight”. It will be a couple of days off for 4.
