I've been searching "Google" to find information on jet takeoff and landing
performance. I've searched AOPA and NBA, but can't find what I want. I'm
looking for a good dissertation on V1, V2, VR, BFL, second segment climb,
etc.


V1 is the take off decision speed. If you lose an engine below this
speed, you shutdown and stop on the runway. If you lose it after
you attain this speed, you continue on the remaining engine(s). Vr
is the rotate speed, where you normally would lift the nose on
takeoff. V2 is the takeoff safetly speed, the (initial) climbout
speed if you've lost an engine. It varies from there depending on
the aicraft, after reaching a given speed (usually something like
V2+10 knots or something), there are procedures for raising flaps,
etc... and new speeds to go with them.

And at least for the 'heavies' I understand these values depend on the
actual loading and density altitude conditions, rather than being
fixed constants.
