Absolutely fascinating, the fuel burns are way beyond what I expected.

One of my favourite sentences is that TOC=TOD !

It all makes sense though.

Not to beat a dead horse, but, on the choice of location for APU, the 727 had a problem with this but for different reasons. Because of the location of the engines that were all mounted at the rear, the Aircraft was quite tail heavy and adding more weight with an APU in the tail section was not desirable.

The solution found that I have not seen in any other Aircraft was to mount it in the wheel well transversely across the keel beam with the exhaust out and over the right wing. Quite unusual but it worked fine with the restriction that it could only be operated on the ground.

Its all academic now but, just out of curiosity could this have worked on the Concorde ?
