Find the barometric pressuse where i live.

[Groupie]

I need to set my barometer, how do i contact to find the pressure where i live, or do i take the number from the weather forecast. I thought it changed with height above sea level My house is 610 feet above.

Probably the simplest way is to take the barometer to your nearest active airport and ask them to give you the pressure there and then. You then simply adjust your instrument on the spot to give that reading - it is now calibrated to read correctly at any location, including your home.

Use one of the online weather forecasting sites, they usually have the ability to input your postcode giving you the readings from the nearest weather monitoring station to your locality. Then select present conditions and set your barometer accordingly. There are thousands of monitoring sites around the UK so you should get a fairly accurate reading for your area

Karl, i'd feel silly doing that, and who would you ask there?

mollykins, this will likely come as little surprise to the staff at the tower. You don't have to be face-to-face with anyone (although at smaller airports you can go to any of the ground staff who will facilitate a direct contact with the tower or else relay the information to you) because once you are there you can telephone them and explain the request, via an operator if necessary or if it is a bigger airport then even any of the airline operations offices should be able to get the information for you. There is in fact another way - if you have an airband receiver you can listen in to communications between the tower and aircraft preparing to leave (this may be a separate wavelength from the general air traffic frequency). It is a rule that at the start of communications the tower announces the barometric pressure to the cockpit contact. No need to feel silly - that does not get you anywhere in this or anything else. Getting an official pressure reading at a proper point of measurement is always going to be much more accurate than if you interpolate from a remote reading (or have someone do it for you). But perhaps inaccuracy does not matter if the barometer to be set is itself not accurate.

Occasionally that lovely Carol Kirkwood announces (on BBC breakfast TV) that there is a very uniform barometric pressure across the whole of the UK – giving an opportunity to check/set barometers against the reported value.

He wants an accurate setting for his altitude, not a mean pressure though.
