What's the highest setting that's usually available on aircraft, in hPa or in. Hg? Only asking because of a news report from New Zealand saying that there could be a high pressure of 1049hPa which is about 31 in Hg.
We can set out altimetet to 1084 hPa which is enough. And I am not 100% sure abuot the lowest, but it should be around 850 or so. And to convert hPa to inHG use 33.865

Quoting WILCO737 (Reply 1): We can set out altimetet to 1084 hPa which is enough.
Thanks for that. I have vague memories of reports from quite a few years ago when the pressure was so high over Alaska at the time, it was almost off the top of the pressure setting range on the altimeter.
I don't know how it is with other aircrafts. I was only talking about the MD11. I think on our 737s the max was 1054.... But I am not sure here either. too long ago
