I have a question in regards to N1 speed and reverse thrust. During reverse thrust does the N1 speed actually increase? Or does it just move at idle and the thrust is simply redirected forwards? I just recieved an Air Tahiti A-340 DVD and during full reverse thrust, the thrust reversers are actuated, and then I saw the N1 speed increase to what seemed to be a much higher N1 than idle.
Thanx in advance,
