Concorde cockpit video: take-off and landing

[Ex-jazz]

Pretty cool stuff and a bit more complicated than the P28A

Thank you for this vid.

Very interesting

Not really, but I know what you're thinking.

See the greatest drag on an airframe is when it is transonic, once you pass the transonic stage drag does drop off some.  In other words, you'll have less drag flying at 1.5 mach, then you will flying at .99 mach.  However you will still have quite a bit more drag flying at 1.5 mach, then you would at subsonic cruising like .8 mach.

In other words drag coefficient in order of highest to lowest goes:  transonic>supersonic>subsonic.

You will always be burning a LOT more fuel in supersonic cruise then subsonic.

Yes, but if you're going twice as fast then a 40% decrease in fuel economy won't matter because you're only burning it for half the time.  Granted, I don't know the exact figures and I'm not even sure it's more efficient at those speeds, but how fast the plane is moving is definitely a factor in all of this.

Didn't some governing agency somewhere along the fleet's operating history impliment a sub-mach speed restriction on the concorde's and their transatlantic flights?  I could of sworn that for a long time they only cruised at ~.9 mach because of this restriction, and that it really hurt them a lot.

Wasn't there restriction over land? They had to do subsonic over land but could punch it at the ocean?

I guess that sort of makes sense, I just see as the sound barrier restricting them until they punch through it.

Thank you for posting that. I don't normally check u-boob links, but I enjoyed that one.


Did you watch this one too?  http://www.youtube.com/watch?v=CD2LRROpph0
