What aerodrome is this?
 

At 51.8484110 N , 0.0074609 W, just off the A10 motorway , roughly halfway between Panshanger and Stansted. Another low-profiler, perhaps, for reasons of their own?

Your co-ordinates don't compute; could you quote standard WGS 84 please?
NB There is a roughly north/south strip just east of the village of High Cross which is near the A10; the village is west of the motorway and the strip is east of it and another to the north east of Puckeridge also close to the A10.

I think it is High Cross

51.8484110N 0.007460W

Apologies, I have no idea of how to adhere to WGS84 standard. An example is welcome! Anyway, it seems the first strip you mention is the one I was referring to. If it is any help, it can be found on a map by surfing to (for just one example) www.openstreetmap.org/#map=16/51.84841111/-0.007460

I could not manage to find the strip N/E of Puckeridge, would you have coordinates (in whatever notation)? Any info on either aerodrome most welcome.

@CGB: yes, that is it indeed. Thanks. I found it at ukga.com, too, though with precious little information. Of the other one, N/E of Puckeridge, not a trace to be found.

I used to fly at High Cross. About 8 aircraft based in the hangar. There was once a small training operation there with 2/3 Tomahawks called Panshanger School of Flying (I did an IMC rating with them). The CFI was the ex Panshanger CFI and owned the name hence the later school at Panshanger was the North London Flying Club!

Very much a private strip for use of based aircraft only.

They compute perfectly well, you have just used decimal instead of minutes. Virtually all aviation maps will use the WGS84 datum. OS maps are not WGS 84 but the aeronautical overprint uses the WGS84 datum. How you express the coordinates largely depends on what equipment you are using.

Jan,

For clarification, "OS maps" means British topographical maps. These maps use a different geodetic datum than the WGS84 datum used by GPS and aeronautical maps. They have a grid of Eastings and Northings in metres but also have a latitude and longitude grid (marked with small crosses).

The aeronautical overprint is adjusted so that a point specified by a WGS84 lat/long is over the correct ground position on the map, but if you were to find its lat/long on the OS map, the value would be different, because the OS map has a different datum.

Clear as mud? ;)

Google Earth claims to use WGS84.
