Is altitude always measured from sea level?
It depends on which area you take flight from. A 5000-mile radius, from the height of the plane all the way down to ground level, is implied in all areas around the ground level of where the plane is. The landscape surrounding the 5000-mile radius will of course be uneven, but an onboard averaging instrument accurately measures out the altitude of the landscape itself. From there, the instrument evenly averages the altitude. That is how altitude is measured these days. ...

Asked in Latitude and Longitude
What instrument measures altitude of an airplane?
The crew refers to that instrument as the "altimeter". It may indicate your actual, physical distance above the ground. Or it may indicate your altitude above sea-level, which can be somewhat risky ... that type of altimeter may read 5,000 feet, which is fine unless you're flying in fog and there's a 5,010-foot mountain ahead. ...
