(Artificial) Horizon / Attitude Indicator

The (Artificial) Horizon, also called Gyro Horizon, or Attitude Indicator, helps the pilot, especially with poor visibility, to determine the attitude of the plane. Also in mountain area an arteficial horizon is very helpful.

By using gyros, air driven by vacuum pump or an electromotor the (real) instrument keeps a stable position and indicates the 'movement of the aeroplane around the instrument'.

Our instrument uses 2 (strong) stepper motors to show pitch and bank information.

The range of the Pitch is -/+ 20 degrees, the Bank -/+ 115 degrees.

The Horizon is available as slave instrument. A master instrument (such as an ASI) is needed to cater for a USB/CANAero connection (see General concept).

The instrument is illuminated by 2 LEDs.

The new (Artificial) Horizon furthermore has: a Slipball, a Fail-flag and a Pull-to-Cage knob.

Pulling (and then releasing) the Pull-to-Cage knob will make the instrument 'cage', ie. take it's current Pitch and Bank as 'the new' zero-reference positions. The Slipball remains unaffected.

When the instrument 'fails', the Fail-flag becomes visible and Pitch & Bank 'freeze', but the Slipball remains operating (since in real it is moved by centrifugal forces).

The instrument is illuminated by 2 LEDs.
