Hmm.....not sure about that one. Firstly, are you sure of the exact type. I know that some airbus family use the IAE V2500 series of engne. This type normally dry cranks for about 30 seconds prior to ingnition, in order to enable the fan blades to settle into the keyways, and to blow unburnt fuel from inside the cowling. The CFM series does not do this, and start is initiated from cold so to speak. I think perhaps a Powerplant mechanic may have a better idea.....
