Starter engagement during engine relight
Hello all,
(With basic reference to Airbus 320/1)
Basically if you are trying to relight a jet engine that has flamed out using starter assist, it seems to me that there is a strong possibility of the N2 windmilling being above the (usual) max N2% for starter engagement.
Is this a limit that is designed for longevity of the starter coupling and therefore can be ignored? I see no reference to max N2 in starter assisted relight in the QRH, however in the limitations for the engine there is a maximum of 18%N2 with the IAE V2500, and 20% on the CFM56.
Cheers
