Glossary A

Aviation refers to the operation and design of aircraft and the infrastructure that supports it, including airports, air traffic control systems, and aviation regulations. The aviation industry includes a wide range of activities, including the design, manufacture, and maintenance of aircraft, as well as the operation of commercial and military flights.

Deutsch: Avtur (Flugturbinenkraftstoff) / Español: Avtur (combustible para turbinas de aviación) / Português: Avtur (querosene de aviação) / Français: Avtur (carburéacteur) / Italiano: Avtur (cherosene per aviazione)

Avtur, short for "aviation turbine fuel," is a highly refined kerosene-based fuel designed for use in gas turbine engines, particularly in aviation and aerospace applications. While primarily associated with commercial and military aircraft, its properties and specifications also make it relevant in the space industry, where reliability and performance under extreme conditions are critical. This fuel is distinguished by its stringent production standards, thermal stability, and low-temperature operability, which are essential for both atmospheric and spaceflight environments.

Deutsch: Achse / Español: Eje / Português: Eixo / Français: Axe / Italiano: Asse /

Axis is the line which an object rotates. A straight line about which a body or geometric object rotates or may be conceived to rotate.

In the aerospace context, "azimut" refers to the angular distance of an object or direction from a reference direction, typically measured clockwise around the horizon. Azimut is often used to describe the direction of an object or feature with respect to a reference direction, such as north or south.

English: Azimuth / Deutsch: Azimut / Español: Azimut / Português: Azimute / Français: Azimut / Italiano: Azimut /

The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith.
