Display measurements on turn coordinator and inclinometer
Aerospace Blockset / Flight Instruments
The Turn Coordinator block displays measurements on a gyroscopic turn rate instrument and on an inclinometer.
The gyroscopic turn rate instrument shows the rate of heading change of the aircraft as a tilting of the aircraft symbol in the gauge.
The inclinometer shows whether the turn is coordinated, slipping, or skidding by the position of the ball.
When the ball is centered, the turn is coordinated. When the ball is off center, the turn is slipping or skidding. The turn rate instrument has marks for wings level and for a standard rate turn. A standard rate turn is a heading change of 3 degrees per second, also known as a two minute turn.
The input for gyroscopic turn rate instruments and inclinometers is in degrees. The turn rate value is input as the degrees of tilt of the aircraft symbol in the gauge. The standard rate turn marks are at angles of ±15 degrees. Tilt angle values are limited to ±20 degrees, whereas inclinometer angles are limited to ±15 degrees.
Combine the turn indicator and inclinometer signals in a Mux block in order:
For example, turn indicator and inclinometer values of
indicate a coordinated, standard rate turn.
To facilitate understanding and debugging your model, you can modify instrument block connections in your model during normal and accelerator mode simulations.
Connection— Connect to signal
Connect to 2-element signal for display, selected from a list of signal names. The 2-element signal consists of turn indicator and inclinometer signals combined 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.
Label— Block label location
Block label, displayed at the top or bottom of the block, or hidden.
Show label at the top of the block.
Show label at the bottom of the block.
Do not show the label or instructional text when the block is not connected.
