Re: Rumour: Spirit FA removed from WN flight - any info?

According to my coworker, the Spirit FA was in unifom, so it wasn't a passenger. I have worked with this FO before and she is very nice, honest and professional; one of my favorite coworkers - I have no reason to believe she would be making this up. Though still hearsay/rumor/circumstantial, it come...

Rumour: Spirit FA removed from WN flight - any info?

Thursday morning flight TPA-FLL. The FO I worked with that afternoon said an NK FA refused to wear her mask once on the plane and was removed from the flight before push. The FO was one of the last ones on and witnessed the altercation in the jetway, with the FA getting very combative, complete with...

Crashes of commercial flights due to pitot covers left on

Not due to ice blockage, not due heat failing, not due to anything else except the covers being left on - maintenance or otherwise. If a GA crash is near and dear to you, then please feel free

Re: CF6-80C2B fuel flow

To start, I would take it's takeoff thrust and multiply by approximately .34, it's (also approximate SL, 0 KIAS, std day) SFC. That will get you close, others here I'm sure

Except of course if a fuselage weighs 500lb/ft, that is 10,000lb of payload advantage for the -700 for the same fuel burn. About 180...

Re: A350-1000 fuel burn

LRC is a reference standard, being 99% best range speed, as it applies evenly across all aircraft, so it doesn't matter if no carrier uses it or all carriers use it, it eliminates variables associated with cost index numbers. So the question stands, is your implication that the A350's LRC is .86+? A...

Re: How much less thrust does a modern high bypass turbofan engine generates at cruise altitude as opposed to sea level?

Our engines make a total of 54,400 pounds of thrust at sea level and approximately 11,800 pounds at top of climb. That is 21.7% of sea level thrust, assuming the cruise flat is just that - flat.

Going by hard numbers, in the 737NG, which at FL400 on our flight an hour ago, was burning 3,550 pounds an hour per engine at top of climb and settled at 2150 pounds per hour per engine at cruise, would have approximately 4666 total pounds of excess thrust available from both engines.
