In addition to Old Smokey's excellent reply (as usual), care should be exercised with regards to light twins, either piston or turbopropellor powered), as climb performance in the climb on one engine can be marginal, at best (except on certain types...the CE441 for example).
It is generally recognised that one needs to attain Vyse to get any sort of positive climb performance. and further, the closer you can get to that speed, while still on the runway, so much the better.
With some types this can be rather difficult, as the aeroplane will start to 'wheelbarrow' on the nose wheel, so a slower liftoff speed needs to be used...with very much reduced climb performance should an engine fail at the most inopportune time.
