It was a normal preflight with everything running smoothly. Nothing on the failures page, good hydraulic quantity, all systems tests pass etc. After engine start I try to taxi to the right and I'm applying 50% N1 just to get the wheels rolling, so I figure something's wrong. At first I deduce it must be a nose tyre imbalance or something, so I double-check the failures page and everything's clean. I then notice that, while both engines are running, I'm only getting a thrust increase from the number 2 engine. I am also getting "LEFT OVERWING" and "RIGHT OVERWING" annunciations on the overhead panel, however this warning, along with the "DOORS" annunciation extinguish after bringing thrust to 40% N1 and back again. I try re-starting the engine but I'm still not getting any thrust from it. The fuel flow is 0.29 compared to 0.47 on the other side. N1, EGT and N2 are also a few units below.Any ideas???Cheers.

The doors warning is a real life nuisance warning that is prevalent with this aircraft type. It is sorta attributed to some specific frequency of vibrations that typically occur during engine accelerations. These in turn fiddle with the door sensors a bit.Continue the takeoff as normal then give the lights a check later.

re-load default panel state. Start again.

Ahh I always thought it was wonky sensors, not slow locks...He he totally wrong on that one
