Re: Concorde - Take-Off and Landing

Thank you for completing my puzzle.

I don't pretend to understand all of it but I enjoy the physics and explanations.

Concorde - Take-Off and Landing

As a layman, I figured out how aircraft "rotate" from watching aircraft carrier ops - via the deflection of the horizontal stabilizer upward. I also understand that aircraft, when they land, - in the "flare", dump lift through the use of spoilers on touchdown. -- I don't see that...

Re: GE9X Engine For Boeing 777X Earns FAA Certification

QQ:

For a new engine:

1. Are they required to have 5000 flight hours - dual engine ops?
2. Do they insist on single engine 5000 flight hours for ETOPS?
3. Does this mean that MTOW is indicated on a single engine?

Ta.

F22 Raptor - Israel

I have read that a part of the reason why this aircraft was never exported to allies was because of concerns that Israel would sell the technology on to Russia.

How true is that?

Re: How do I include pictures in a post

"Unfortunately our forum platform doesn't allow users to upload images."

So the question then becomes, how do we upload to the airliners database?

That's a shame as I have some very nice flight jackets - some WW2 US/ German made to exact spec.

Military Flight Jackets

I've been wearing them since 1987. I've crashed an FZR 600 in them, got drunk in one and tore it badly - and gave one to an old girlfriend who loved it. One of my friends from school borrowed my Eric Hartmann hand-made replica and doesn't seem to want to give it back (he's had it for over 10 years)....

Plenty of people hide behind emails and some will use it against you without taking responsibility for their short-comings.

DP is sold to us as a deterrent. For most, that works. For the rest - the ones that it is really applicable to - don't believe that they will be caught. And then they often do get caught. With good evidence, why not exact revenge? That is also a part of a punitive sentence. But criminal prosecution ...

It is very interesting that aircraft navigate magnetically. I assumed that it was electronic fix/ bearing with GNSS - TRUE bearings.

Thank you GF - it leads me to a few other questions:

True is primary and Magnetic is backup? Or the other way around?
