Absolute altitude Solution

Follow our step by step solution on how to calculate Absolute altitude?

FIRST Step Consider the formula

h a = h G + [Earth-R]

Next Step Substitute values of Variables

∴

h a = 28991m + [Earth-R]

Next Step Substitute values of Constants

∴

h a = 28991m + 6371.0088km

Next Step Prepare to Evaluate

∴

h a = 28991 + 6371.0088

Next Step Evaluate

∴

h a = 6399999.8m

LAST Step Rounding Answer

∴

h a = 6.4E+6m

How to Evaluate Absolute altitude?

Absolute altitude evaluator uses Absolute Altitude = Geometric Altitude+[Earth-R] to evaluate the Absolute Altitude, Absolute Altitude is a measure of the height of an aircraft above the Earth's surface, calculated by adding the geometric altitude to the Earth's radius, providing a more accurate representation of the aircraft's true vertical distance from the center of the Earth. Absolute Altitude is denoted by h_a symbol.

How to evaluate Absolute altitude using this online evaluator? To use this online evaluator for Absolute altitude, enter Geometric Altitude (h_G) and hit the calculate button.

FAQs on Absolute altitude

What is the formula to find Absolute altitude?

The formula of Absolute altitude is expressed as Absolute Altitude = Geometric Altitude+[Earth-R]. Here is an example- 6.4E+6 = 28991+[Earth-R].

How to calculate Absolute altitude?

With Geometric Altitude (h_G) we can find Absolute altitude using the formula - Absolute Altitude = Geometric Altitude+[Earth-R]. This formula also uses Earth mean radius constant(s).

Can the Absolute altitude be negative?

No, the Absolute altitude, measured in Length cannot be negative.

Which unit is used to measure Absolute altitude?

Absolute altitude is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Absolute altitude can be measured.
