Jump to postI don't think this is an engine out issue. Those are trained so often in the sim, should not be a problem.

Jump to postThere would probably be engine oil on the runway if the oil lines had been severed and oil was being pumped out. Fuel as well, but that would evaporate rather fast. And hydraulic oil too.

Thanks for the link. Very good video. It`s hard to get information on how the airport is doing.

Jump to postWow, that video clears up some things: - At 2,5°, the pilot has to use all his force to control pitch. And he doesn`t even have the feel system , thinking they are approaching stall, adding a lot of force on top of that. So in the MCAS situation, pitch would not be controllable from 2.5° ND trim for...

Jump to postSeems consistent to me. Apart from the altitude issue, that's with the speed? Close to 400 kts less than 1000 ft AGL seems excessive. That is an interesting point.

I think punishment and huge fines are justified, but would not repell those idiots.

Jump to postSo I looked at the FDR data today and yes, it seems there is a similar offset for airspeed (3-5% offset) and altitude (5-8%), just from the graphs.

Jump to postI disagree. For me a tube is a cylinder. And that`s not wht the Avanti is. It`s body is no tube, it`s basically a wing which approximates an NACA airfoil, creating 20% of total lift.
