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

So you count to 30 while you take off, at the right speed? Watch the
second hand?

I think there has to be one of the other rules to follow that are a

than that!

Or was that an attempt at humor? If so, I couldn't tell.

Well, it works for carrier based aircraft.
