30-second Rule.
If you are not airborne in 30-seconds, abort, something is wrong.
Sort it our on the ramp.

On the Falcon 50EX there is a "G" meter. If the airplane won't make the
proper horizontal "G" on takeoff it means abort. The nice thing about this
is that max "G" is right at the start of the TO roll.
