I believe people here are getting airfield elevation mixed up with QNH.

How in hell would any pilot get that confused??????????????

Right so you just posted a load of info explaining how airfield elevations are not changed daily but are calculated using sophisticated surveying techniques which is what I explained, why do they bother when they could just go to your hobby website and get the latest one hourly eh?

That's exactly what I'm saying, it seems to confuse you.

I was taught to set it to the destination from the chart value, while en route and close. I realize it could be advised differently, elsewhere in the world.

Explain to me Slipball how you are going to get an accurate enroute altimeter setting from the chart elevation values???

The only thing you can do if you don't have a radio is set to the field elevation of the departure airfield.

Once you are airborne, you cannot look at an arrival airfield elevation to glean any useful current altimeter information.

That's true without a radio, and I did set to listed value of chart.

How? are you saying you set an arbitrary QNH based on the known field level at destination before you took off? which basically means you were flying on the wrong pressure setting at your departure.

Read what I wrote and not what you think or wish it says:

NO, I said the current settings do not agree with the elevation and not all charts are the same.

Look under METAR and be advised it changes with conditions. the current settings do not agree with the elevation and not all charts are the same.

It will vary from 597-600 depending on which site you check. I checked several sites and plates before I posted.

Here it is 600 today:

Here it is 597 today:

Elevation 182m (597ft)

In otherwords, for you games testing an approximate is good enough. If you set your games altimeter to field elevation, you will get the pressure at sea level.

If you spawn at several airfields around the map, you can see if it changes and confirm the values.

The analog altimeter can be set by either setting the altimeter hands to the correct altitude, or the sea level barometric pressure.

I dare you....

I assure you that Jeppesen, Aerad and other established providers of official aeronautical data will comply with the same values set out in the official AIP of any state, any variations you find on erroneous websites are your problem, us professionals stick to the propper sources.

The barometric altimeter can be set to anything you like within its scale range, if you set another airfields 'guessed' QNH based on it's elevation at the field of departure then 1. you are on the wrong pressure setting for departure 2. the wrong setting for en route 3. the wrong setting for arrival because the pressure could have changed by then.
