One or two questions...
At what point did you notice the #1 engine wasn't up to full power?
Which Dornier is this? What engines?
DO28 with G-92 D2 Engines. I noticed as soon as the RH spooled up normally and the swing started, about 3 seconds I guess. By which time I was tail up and ready to fly.
Is normal procedure on your aircraft not to advance power levers to a mid-position, pause to allow to stabilise and then advance fully?
No, mid position, spools the engines up to around 25% torque then as we accelerate the engines continue to spool up and at take off we are about 50% torque and then advance the torque as we climb to 68%. We never advance fully on the ground as it will exceed both torque and ITT limits, not to mention the controllability issues of putting that much torque out. It is quite normal to get a 'split' as we spool these engines and so we get used to leading with the slower engine. Unfortunately no two in the fleet 'split' the same way. It is not helped by the fact that it is very hot out here.
Is this single or two-crew?
Single Crew
Any autofeather facility on the aircraft?
Yes. Auto-feather would not kick in at the torque output.
Any hint from a hangar as to the reason for the lack of spool-up?
Fault with the fuel controller unit by the look of it.
