Guarding the thrust levers, against what? No use for rollbacks, flameouts,
bird injestions etc. Do these levers ever creep back, or forward on their own? That TOGA indent. Doesn't the "indent" hold?
Also wondering on the Airbus where the levers don't necessarly move with changed power settings, if this effects T.O. , but I suppose A.T, normal law, etc doesn't apply during T.O. ?
And if the captain is sometimes the only one able to abort, would he want a young F.O. blocking the levers?
None of mine moved on their own except when a certain part broke and a spring took it to full throttle. By the third time, I was an old hand at it.
