Re: Runway Incursion at JFK 1/13/23

Related to the CVR issue, and not judging the crew in any way - does the 'sterile cockpit below 10K' rule apply whilst on the ground taxiing?
I would have thought so - especially at one of the World's busiest airports.

I don't follow the dynamics of how the damage from inside to outside implies the gear was down. Even with the trunion door in the open (vertical) position, it's still outside the arc of the engine so I don't see how turbine blades could get 'behind' it so as to penetrate from the inside out.

Since Flap 1 extends the LE devices I'd say that there'd be considerably more than just 'a small amount of extra lift generated'. The leading edge devices don't so much increase lift as increase the AoA margin, though of course as you "use" the higher AoA, you do get more lift. Either way...
