Hey guys,

was looking at this shot a friend of mine posted. It seems weird that the APU has a plug in it, does the aircraft even have an APU that it uses or is it just sealed?

Was just taking about that at work, and some inspectors went to do some contract work on the Dreamlifter. They said it didn't have a APU, the picture seals it to me. HTH

No APU, according to comments on this thread:

Nope. If it did, they'd have had to run the fuel lines and pneumatic ducts through the tail hinges...given that it only ever visits a very few airports, it was simpler just to remove the APU and use GSE carts.

Like Tom said, there's no APU. Since the airplane only has to operate at very few airports, they don't need an APU since they can use ground equipment. Routing fuel and pneumatic ducts through the hinge would have been quite difficult. The hinge with its hydraulic tubes and flight controls cables is already complicated enough.

If you have never designed an airplane part before, let the real designers do the work!

In the Aft section open position there are no ducts heading aft........No APU.
Ground cart would service the purpose.
