DEFINITION OF DISPATCH
It all depends upon the definition of dispatch.In some places its WHEN YOU APPLY THRUST FOR TAKE OFF, at others its WHEN YOU START TO TAXI UNDER YOUR OWN POWER for the intention of taking off.Once dispatched you can consider just applying the QRH.However the final authority is with the PIC as always.If its something you can live with well........otherwise if its a safety concern or might ground you at the next place in the middle of nowhere better to RTG (return to the gate).When conducting command training I notice many many trainees getting too hung up on this area from a legalistic viewpoint instead of applying common sense.Like SOPs.Theyre only a guide not intended to be black and white court rulings.Chill.
