Altitude compensation option

[rugomol]

I have researched on the topic of this question and found topics like this

Barometric Compensation Algorithm

Yep. Just the MSL. I am not clear on if you are saying there is an option I can click that sill provide this info. Can you elaborate on what you mean by the ellipsoid?

A couple of questions about Barometric vr Geometric altitude measurement

I recently watched a helicopter do a short 20 minute circuit around my site (361 ft elevation according to heywhatsthat.com) and land at the nearby Oaksey Park Airfield (EGTW) about 8.5 miles distant (299 ft) The thing I am curious about was from my SkyAware GUI I watched the reported altitude descend to minus 200 feet Barometric (no reading shown for Geometric) when it touched down. This got me thinking about the reliability of the altitudes reported in the aircraft.json or at least how to in…

Also I found that Fligtfeeder represents two types of altitude

alt_baro - Barometric altitude of the aircraft [Signed Float]
alt_geom - Geometric altitude of the aircraft [Signed Float]

For example
Aircraft: 508424
Altitude_geom: 37125 ft
Altitude baro: 37000 ft
