What a load of ridiculous speculation!
1. 20 min turnrounds are possible PROVIDING everything fits into place. Often achieved by EZ aat EDI,GLA,BFS with NO reduction in the safety of the operation.
2. Absolutely impossible at LTN as the airport can't cope.
3. The PF for the next sector normally stays on the Flt Deck to prepare things whilst the PNF goes walkies.
4. EZ 737s are operated STRICTLY within the MEL/CDG. I have never even heard a hint of anything different.
5. Saving money by using a lower autobrake setting???????? Not a chance!
