still have 500 feet to go?

On my last couple of short flights on the Learjet I have noticied the altitude clock is still showing 500 feet to go as my landing gear touches the runway, Anybody know why this is happening

Most likely your Altimeter isn't set. Press B to set it.

The Altimeter reads feet above sea level, if the elevation of the airport is 500 ft. than that is approximately what your properly set Altimeter will read on the runway.
