How can you measure attitude?

Answer 1

I guess you meant altitude.

The most often used units are feet and meters.

Russia and its surroundings are the only countries to use meters for altitude as far as aviation is concerned.

Altitude is then measured with a barometer. International Standard Atmosphere has a decrease of 1hPa per 27 feet. Standard Atmospheric pressure at sea level is 1013,2 hPa, or 992 InHG. Aircrafts use this altitude although it's a false one since, anyway, everyone up there as the same error. As far as terrain clearance is concerned, they use Ground Radars below 2,500 feet.

The pressure altitude is then corrected for real atmospheric conditions if real altitude above Main Sea Level is needed. Pressure at sea level and temperature are then needed.

Another and easier way to get real altitude is to use GPS with a cover of at least 4 satellites.

Answer 2

Attitudes can be measured using self-report measures like surveys or questionnaires, behavioral measures like observations of actions or reactions, and physiological measures like measuring heart rate or brain activity. Combining different methods can provide a more holistic view of an individual's attitudes.
