Motoring After Deicing
A few days ago our ground engineer suggested on the intercom to do a motoring (let the engine run for a while) before placing the start levers to idle (i.e. before ignition), after deicing was complete.
I must admit I had never thought of that.
Bleed valves were already off, and I would have waited one minute after eng start to turn them on, but motoring the engine before opening the fuel was new to me...
Does it make sense to you?
Any residual glycol would be cleared anyway before opening the bleeds, but maybe it's a good idea to avoid burning the glycol inside the combustion chamber?
