Great stuff. What are you using for your altitude information though ?

[322Sqn_Dusty]

Something like this I guess?

http://www.raf.mod.uk/raflyneham/raf...55130C1227.pdf (opened on 18 May 1940 as Number 33 MU).

They speak of pression regions. This refers to Altimeter Setting Regions (ASRs). The QFE (Field Elevation) is for the field reading only. So indeed VBF-12_Gosling's, Enroute Supplement - Channel, is handy for the fields on approach and operating (thank you for those!). Most of the time (nowadays) the standard pressure setting 1,013.25 [hPa] is used for transits on flightlevel. Imho when running a dedicated server (and for the die-hards) it could be the case that the settings are given in a briefing. On deciding the field the pressures are given and the pilot takes note.

And for those that can't be bothered with setting up the gyro's compasses and altimeters.. ..

You could also have a read on the NATS website... checkout http://www.nats-uk.ead-it.com/public...Itemid=11.html and scroll down the page until you find "Altimeter Setting Procedures". This explains how it should be done today.

Also look at the links on the left hand side. You can select "Aerodrome Index - Specific" and for those airfields still active, i.e. Biggen Hill, pull up the aerodrome chart. Biggen for example, has an elevation of 599ft amsl.

Indeed a good read. I don't know how much the methods differ from the RAF during WW2. Multiple sources give opposite answers (crews pilots). I'm aware that we don't fly software as FSX etc and most won't bother and just spend some ammo on targets, i find it interesting to 'fly' the Cliffs as the original crews and pilots did as far as ingame realism lets me.

How 1C imagined this is one of my questions.

[Varrattu]

For every flight / take off the REICHSWETTERDIENST prepared a weather forecast for start location and destination. Also included was the QFE for departure aerodrome and destination aerodrome. For this they used the form --Vordruck RWD F2--.

I haven't got CLOD yet (waiting for a PC that will run it) but one thing that won't have changed in the last 71 years is terrain elevation so I guess I'll check out airfield elevations via any modern map - perhaps Google Maps or something similar will give elevation info for those not resident in the UK? It doesn't need to be exact since baro pressure is constantly changing anyway. I've also got old aviation charts lying around.

[322Sqn_Dusty]

Interesting test.

[IvanK]

You can determine the exact elevation in metres using FMB. Place an object on the ground then read the Z co ordinate in the bottom left corner. Using this you can determine each airfields elevation. If you park your aircraft on the ground and set your altimeter to the exact known altitude you then automatically have the correct atmospheric pressure (QNH) for the map.

Here are all the UK airfield elevations obtained from QMB and verified in game. I will compile the whole lot into a single PDF once all the data is in. Apologies to the French if the spelling is a bit off

I can get radio messages telling me to join the pattern if I put airport towers up, so its not that there are no messages, just cannot figure out how to make radar ones work.

On the other hand, even removing all radar objects (except the map default ones), I can receive reports when 2 flights of aircraft get within visual range of each other. Even testing from the German side, where there are no map default radars, I can get contact reports as long as German aircraft (AI or Player) get within range of enemy a/c.

I've tried at least 20 times, adding up to 50 radar stations of all types onto the map, and consistently these are the results I get. However, I could still be doing something wrong, (maybe a script or trigger set?), so it might be possible in game to get radar, but neither I nor anyone else I've asked can figure out the method.

Guys (Cheesehawk and IvanK), thanks for the explanation and effort that you've put into this.

When the dynamic weather is fully integrated I'm looking forward to seeing where it takes us. I like to fly full real and am hoping that we'll have to take account of pressure settings for navigation and finding the enemy. I also imagine that knowing the height of an aerodrome above sea level might be useful for high level bombing - but currently that's a whole part of the game I've yet to look into.

[Osprey]

No Gravesend in the list?

Still, I understand it's too risky to bomb, what with No.501 County of Gloucester being stationed there
