Turn Coordinator

Display measurements on turn coordinator and inclinometer


Flight Instruments


The Turn Coordinator block displays measurements on a turn coordinator and inclinometer. These measurements help determine if the turn is coordinated, slipped, or skidded. The turn is a coordinated turn that combines the rolling and yawing of a turn. The turn indicator signal turns the airplane in the gauge, in degrees. The inclinometer turns the ball in the gauge, in degrees. Together, these signals show the slip and skid of an airplane as it turns. Both turns cannot exceed +/–15 degrees. If values exceed 15 degrees, the gauge stays fixed at the minimum or maximum value.

Combine the turn indicator and inclinometer signals in a Mux block in the order:

  1. Turn indicator

  2. Inclinometer



Select a 2-element signal, consisting of turn indicator and inclinometer signals combined together in a Mux block, in degrees. You connect and display this combined signal. 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.


Name of connected signal.

  • Top

    Show label at the top of the block.

  • Bottom

    Show label at the bottom of the block.

  • Hide

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