James Pimenta Posted February 14, 2021 at 09:12 AM Posted February 14, 2021 at 09:12 AM I noticed that when flying in the UK I am only told the setting in hectopascal (hPa) and never Inches of mercury (inHg) by ATC. This includes when listening to the ATIS. I don't have a problem with this, I was just wondering is this the standard unit for Europe? Link to comment Share on other sites More sharing options...
Trevor Hannant Posted February 14, 2021 at 09:45 AM Posted February 14, 2021 at 09:45 AM Yes, and many other regions around the world. 1 Trevor Hannant Link to comment Share on other sites More sharing options...
Christoph Reule Posted February 14, 2021 at 10:00 AM Posted February 14, 2021 at 10:00 AM Hectopascal (hPa) is the standard altimeter setting for Europe, exempt very few U.S. military installations (like Ramstein/ETAR or Spangdahlem/ETAD) which report air pressure in InHg. 1 Link to comment Share on other sites More sharing options...
Andreas Fuchs Posted February 14, 2021 at 10:13 AM Posted February 14, 2021 at 10:13 AM hPa are used in all countries of the world, except for North America and Japan (and some US Air Force bases around the world). In Russia (and some other ex-USSR countries) you can request the altimeter setting in "Millimetres of Mercury", in case that your aircraft needs it, but they are using hPa by default. This makes inHg a rather exotic unit to be used (like degrees Fahrenheit). This is just a fact, not a judgement (in case that someone choses to take offence in calling "his" unit as something exotic! (need to take care with the wording these days). I personally enjoy using inHg when flying in the States, Canada or Japan, it's different from our boring standard stuff. https://en.wikipedia.org/wiki/Altimeter 2 1 1 Cheers, Andreas Member of VATSIM GermanyMy real flying on InstagramMy Twitch streams of VATSIM flights and ATC Link to comment Share on other sites More sharing options...
