Could you tell us what the APU does....is it what initially provides power to the plane The Auxillary Power Unit APU provides electrical power and compressed air on other models to the aircraft when the engines arent running.Have these engines been fully tested already and now they are being tested to see if they work with the rest of the plane Yes theyve been fully tested elsewhere and even flown on other aircraft. Its just a matter of confirming the 787s systems and airframe interaction with the engines is as designed.That is, will there be special testing when the GE engines are on the planeThe GE engines are likely to require another set of tests to validate their interaction with the airframe.Do they have to refuel this plane when these tests are completed Most likely yes at some stage, though it would depend on the fuel load Boeing would like the 787 to carry for first flight.
