# Why do planes accelerate when they touch down on a aircraft carrier [duplicate]

I was watching a plane documentary, and when the part about aircraft carriers came on, I noticed that as soon as the plane hits the aircraft carrier runways, the plane speeds up. Why is this happening?

The question has not been answered in What is the procedure for landing on an aircraft carrier. This question explains the procedure to throttle up to full military power just after touchdown, however does not address the reason for doing so.

• @Federico: That answer does not. It does not even mention it! This one does, though. Jun 5 '15 at 11:53
• how can you say that it does not? Additionally the higher thrust setting minimizes any spool up time because you are already near max thrust. what is this?

• anyway, more than one answers mentions the why, hence this is a duplicate.

• @JanHudec the sentence before: Upon landing this thrust becomes excess thrust enabling the aircraft to more quickly accelerate and get safely airborne in the event of a bolter.
