Absolute Altitude Meaning, Synonyms, Antonyms, Translation, Use Cases  

Absolute altitude

Have you ever heard of the word absolute altitude, if not, in today’s word for the day, we will give you a highlight on the meaning of absolute altitude, its synonyms, antonyms, translation, and how to comfortably use it in a sentence.


Absolute Altitude is defined as the vertical distance between an aircraft and the surface over which it is flying. 

(Noun) (countable and uncountable, plural absolute altitudes) (Aviation) The vertical distance between the airplane and the surface below.

The height covered by a plane, aircraft, or rocket above sea level is seen as absolute altitude.

This height is measured vertically from the ground level with the use of an electronic altimeter or it can be called an absolute altimeter.

An altitude can actually be term negative, considering when the object is below sea level. 

Take, for example, a bird flying into a canyon that is below the mean sea level. We say the altitude of that bird to be negative.

First Known Use 1916, translations: Latin altitudinemOther terms that came into use in English about the same period include saddle stitch, logical positivism, preset, and acoustic phonetics.


Use cases

  • The assistant pilot could not get the correct absolute altitude to land the plane at the California airport.
  • The airport radar altimeter wasn’t functioning for the pilot to calculate the absolute altitude which ended up causing a delay in his first training.
  • The radar altimeter measured 20000km between the ground level and the plane for the airport to know the absolute altitude of the landing plane.
  • There was a negative altitude of the plane which affected the absolute altitude calculation of the plane.
  • The pilot was not disturbed as sea level has nothing to do with absolute altitude when passing through the Atlantic ocean. 


Video Explanation on Absolute Altitude

We define absolute altitude as the vertical distance of an aircraft to the ground. We take the measurement of an aircraft in Feet AGL (above ground level). 

The only similarity is absolute elevation and true altitude. But true altitude differs, as true altitude is the measure of the vertical height above mean sea level and not above ground level. 


Frequently Asked Questions

How to find the Absolute elevation?

we make use of a radar altimeter, which produces a wave and is calculated on the reflection of the wave from the ground back to the plane, which is limited to 25000km.

What are the five types of altitude?

Indicated altitude: this is the altitude that is read directly from the altimeter.

Pressure altitude: This is the height of the aircraft above the standard datum plane at which the altimeter setting will theoretically equal 29.92 inches of mercury at 15 degrees Celsius.

Density altitude: can be gotten when pressure altitude is adjusted for the non-standard temperature.

True altitude: True altitude is the vertical distance of an aircraft above sea level.

Absolute altitude is the measurement of the vertical distance of an aircraft above ground level. 

How is altitude measured in aviation?

Altitude is majorly the measure of the vertical distance or height between a reference point and an aircraft. In aviation, measuring the altitude is complicated as before the altitude is measured the type of altitude to be measured needs to be identity before taking the measurement.

Does elevation affect temperature?

Yes, elevation affects temperature, the temperature of a particular area changes and varies and could be based on tall buildings, shades, and sun.
