V1?
No V1 with the 411, Huck, it's a CAR 3 certificated aeroplane.
Now, as to rudder force to keep it straight in the air, with one engine unserviceable/propeller feathered, at the published Vmca speed/max weight, it would be 140 pounds...which, oddly enough, is about the same as an old straight pipe powered B707-300 with an outboard engine failed at rotation.
Yeah, I've flown these too, extensively.
Now, to look at the reasons why the Comair accident occured, a rather long investigation by the NTSB will certainly be necessary.
But, when was the last time a professional jet transport crew attempted departure on an unlit runway, during the hours of darkness, and at the same time failed to note that the runway magnetic track was positively NOT what it was supposed to be?
To NOT notice these very basic errors, leads me to believe that the crew was not properly trained, and further, that the specific airline has poor standard procedures.
Crew 'fatigue?'
Phooey.
They had the mandated rest, and that should be sufficient.
Sorry, so-called fatigue, as well as poor pay are red herrings with this accident.
