Not sure which thread this should be in..and apologies if its already been done..
Was any mention made of that spotter video doing the rounds which shows his extremely long takeoff run on the day in question?
Yes , the departure is covered and it notes a few points: the t/o was downhill with some tailwind component, the engine parameters are not specified but, described as "normal"(or words to that effect), the rotation was non-standard.
You have to read all the report to get the detail. Overall, I am not impressed with the analysis of engine performance in the whole report. There seems little attempt to accurately assess the performance of the engine in that t/o where known details exist. The whole report notes deviations in engine performance and instrumentation that include multiple gross overspeeds on test flight, gross undereading JPT indications and fuel system degredation. I don't really understand why the performance on that t/o is not fully tested, after all, it must have been a full throttle event.
Maybe there was a problem with using this engine at full throttle-how can we know?
