Artificial Horizon

Represent aircraft attitude relative to horizon


Flight Instruments


The Artificial Horizon block represents aircraft attitude relative to horizon and displays roll and pitch in degrees:

  • Values for roll cannot exceed +/– 90 degrees.

  • Values for pitch cannot exceed +/– 30 degrees.

If the values exceed the maximum values, the gauge maximum and minimum values do not change.

Changes in roll value affect the gauge semicircles and the ticks located on the black arc turn accordingly. Changes in pitch value affect the scales and the distribution of the semicircles.

Combine the roll and pitch signals in a Mux block in the order:

  1. Roll

  2. Pitch



Select a 2-element signal, consisting of signals for roll and pitch in degrees, to connect and display. This input cannot be a bus signal.

To view the data from a signal, select a signal in the model. The signal appears in the Connection table. Select the option button next to the signal you want to display. Click Apply to connect the signal.

The table has a row for the signal connected to the block. If there are no signals selected in the model, or the block is not connected to any signals, the table is empty.

    Do not show the label or instructional text when the block is not connected.
