Look under METAR and be advised it changes with conditions. It will vary from 597-600 depending on which site you check.

Here it is 600 today:

Sorry Crumpp but this is nonsense and if you are a commercial pilot you'd know it, an airfields official elevation is fixed and defined according to an average sea level in 'official' aeronautical publications not some obscure hobby website, MDA's and DA's are based on threshold elevation and are defined to individual feet, you 'do not' have variable MDA's or DA's according to Wx changes, next time a real pilot lets you look at a Jeppessen approach plate you will see what I mean, having flown a Learjet45 in and out of Biggin Hill on countless occasions due to the company I worked for being based there I believe I can make comment.

BTW EGKB's official elevation is 599 feet as defined in the UK AIP and official charts
