We see so many engine runs in the Engine test area and RTOs after some flights within the last weeks.
All Qatar frames do get new engines before delivery, test flights before CAF done with other engines.
I find this kind of a thing a bit strange. Firstly, they are surely going to get billed for the use of, shall we say, surrogate engines. Second, isn't it a good thing to test your own engines well, before accepting them?
I assume that the engines are anyway owned by RR, also the new ones for Qatar being power by the hour. There will be quite a while Qatar frames being test flown at TLS. How many are up are any time, two with four engines?
Is this really true? Currently we have four Qatar-Planes outside. Two A350-1000 and two A350-900.
This means Airbus have eight ore more Spare-Engines only for Qatar Airways.
The ones at the delivery center should have the engines that they will be delivered with.
Sure, but with the information from the history we must expect that Airbus has eight Spare-Engines only for test flight and that is a lot.
Airbus can be lucky that other Airlines have not the same requirement
