I have also raised the issue of Airfield height/Circuit heights a couple of times to no avail!
Showing circuit height as a combined AGL circuit height ( QNH) causes confusion to anyone who uses QFE as is mainly used in the UK by ATC.
Can we please have Airfield Height shown in AGL and circuit height shown separately as per all UK guides Pooleys/AFE or even Skydemon.
Alan, we added the AGL specially on your request. IMHO AGL is hardly used. I really don’t see how airfield height can be done in AGL, its always zero?!
We talked about the AMSL/AGL combined display and as suggested by another user we did not add AMSL/AGL to the numbers to avoid cluttering.
Density altitude is currently calculated indeed from current METARS and TAFS, but in the future we plan to use the DWD icon model data also to be able to forecast density altitude further in the future and further away from a metar/taf station.
Yes I meant to say amsl however however it is still not shown correctly. I can only suggest you look at all the airfields in Pooleys or look how Skydemon do it and show circuit height.
Currently Ev4 shows my home airfield, Calton Moor 990ft ( no clarification of what 990ft is?) it then shows Circuit Altitude as 1790ft amsl.
What it needs to show is Airfield height at amsl, in this case Calton Moor 990ft amsl. Circuit Height 800ft agl (QFE)Then there is no confusion betweeen QNH and QFE. If someone does want to fly QNH then so be it, but the majority of pilots in the UK when landing at an airfield use QFE as a base point altimeter setting (height above airfield threshold) which is what ATC will give them when joining the circuit. QNH for landing is not usually given or only on request.
The norm in training in the UK is still to use QFE.
Traffic pattern in most european countries is given in AMSL which generally is about 1000 ft above airfield alt also in AMSL and sometimes m !
sorry to intervene. We will not implement the UK system in Europe.
altitudes shown in Numbers - be it a TP or an airspace- is always MSL
(altitudes) in brackets are generally heights. This is ICAO standard.
I feel a Brexit moment coming on!
