FS Altimeter Problem

I'm using FS2004 and I'm having a bit of a problem.

For example last night I was flying into St John's Newfoundland whose runway is at 460ft. Naturally when I land the altimeter says 460ft. Obviously I don't know my correct height above the ground.

The question is how can I change the altimeter to read 460ft as 0ft so i know the correct height to flare? When in the flight would be the correct time to make that adjustment?

Thanks for your help.

and with that..cabin crew, seats for landing please.

That's not how its suppose to work. The pilot is expected to know the altitude of the airport and be able to figure out the right altitude etc. You could try to figure out by changing the barometric pressure of the altimeter. Standard is 29.92inches but this all depends on the weather etc.. Some airplanes had radio altimeters and those altimeters separate from the normal one will turn on around 2500ft and tell you how far above the ground you are in feet. And will give the correct read out your looking for. But for the normal altimeter, what your asking just does not happen in real life, and would be difficult to figure out.

It does happen - it's called QFE, and it is very rare (for the reasons you described).

I've never done it that way - I just take whatever the field elevation is, add 30-50 feet to it (for a larger airplane), and that's when I begin my flare.

Thanks for the info, never knew that. But again I would imagine it is very difficult to do, as you stated its rare.

In FS I fly the airliners, so I always have a radio altimeter handy to take care of any guess work.
