hican anyone tell me where i can get some information regarding V1 Vr N1 and N2 etc etcso i know what all these meanthanks

Hi CheckpointCharlie,On take-offs, you don't abort your take-off beyond V1 speed, of course unless it's really critical, and that the problem cannot be looked at in the air, or the captain is certain it's too dangerous to lift off or have doubts that the aircraft's ability to lift off.At Vr speed, start rotation! (Vr is for Vrotate).N1 and N2 are engine indications.

Hi Clayton,Try this site for V speed definitions.http://www.aviationboom.com/terms/vspeeds.shtml
