This artificial horizon consists of a graphical object representing the attitude and heading of an aircraft, with the following elements:
- Virtual horizon line between sky and ground symbols
- Reticle symbolising aircraft longitudinal axis
- Flight path marker
- Attitude indicators :
. Pitch indicator, range : ]-180°,+180°], field of view : 40°
. Roll indicator, range : ]-180°,+180°], field of view : 60°
. Heading indicator, range : [-90°,+90°], field of view : 60°
All attitude gauges have the following characteristics:
- Reference markings : cardinal points, null pitch and null roll
- Resolution of 2.5° for graduating
- Specific graduatings for modulo 2.5°, 5° and 10° angles
Attitude can be updated by an object method through the three Euler angles [rad], respecting this aeronautical convention: from an initial attitude (North, horizontal flight), heading, pitch and roll angles respectively increase when:
- Aircraft turns to the East
- Aircraft climbs
- Right wing goes down
