YearoftheTiger ,
Good sources of detailed drawings are the 'IPC' (illustrated Parts Catalogue) and the 'SRM' (Structural Repair Manual).
Originals (paper) are rarer than the proverbial rocking horse poo.... but they also exist on CDs. Those occasionally pop up on the well-known auction site, but maybe some of the readers here have them and would be willing to make you a copy.

Also see my PM.

MIA-IAD is less than a 1000 nm hop, so the question is really "was the fuel cheaper in Miami, so they tanked up there and only topped up in Washington?" (unlikely, flying fuel around is a waste of money in most cases).

Otherwise, the max fuel on Concorde is listed as 26,400 gallons (Imp), so if you feel like it, you can do the sums with the figures quoted on the Heritage Concorde site.

There are people on here far more qualified, but i believe using the much higher frequency all but ruled out interference from any other aircraft system for the control signalling to the flight control surfaces
Gordon is right: the flight control inverters converted the 28V DC aircraft supply to the 26V AC 1800Hz that supplied the flying controls.
And the 1800Hz was chosen because it's halfway between the 4th and 5th harmonic of 400Hz, so yes, it minimised interference of the 400Hz main AC supply in the flying control system.

consub,
Slightly amazed about your note re the 5400 series TTL being embargoed.
I pulled a random board from "my" AICU, and all of it is 5400 series, datecodes 71 and 72.
I hope you can tell us some more...
I've been sniffing round the boards, but I haven't found the CPU or the clock... and yes, I know the AICU dates from before the arrival of the microprocessor!

leb001,
I'm afraid 1-GEE is a nonsense registration. A British Concorde registration would be "G-" followed by four letters.
But, if you can post a photo of the painting, it may be possible to determine which aircraft it is.

leb001 ,
While it's a nice pic, the artist has been taking a fair amount of artistic liberties....
For instance, the door located at the forward end of the wing, just forward of the emergency exit, is pure fiction.
The tail is something between proto and production.
As said, the registration is a few paint smears, and does not correspond to anything real.
AFAIK , G-AXDN (01) never had a British Airways livery.
I'd suggest the picture could have been inspired by DG, or SA (but in that case the BA livery is on the wrong side), or one of the production aircraft delivered to BA in the period that livery was used (such as G-BOAC).

I would consider it as a generic British Airways Concorde from the early days. I don't think there was an attempt to carefully depict one particular aircraft.

Hope this helps!
