Display measurements for aircraft airspeed
Aerospace Blockset / Flight Instruments
The Airspeed Indicator block displays measurements for aircraft airspeed in knots.
By default, minor ticks represent 10-knot increments and major ticks represent 40-knot increments. The parameters Minimum and Maximum determine the minimum and maximum values on the gauge. The number and distribution of ticks is fixed, which means that the first and last tick display the minimum and maximum values. The ticks in between distribute evenly between the minimum and maximum values. For major ticks, the distribution of ticks is (Maximum-Minimum)/9. For minor ticks, the distribution of ticks is (Maximum-Minimum)/36.
The airspeed indicator has scale color bars that allow for overlapping for the first bar, displayed at a different radius. This different radius lets the block represent maximum speed with flap extended (VFE) and stall speed with flap extended (VSO) accurately for aircraft airspeed and stall speed.
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 signal for display, selected from list of signal names.
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.
Minimum— Minimum tick mark value
Minimum tick mark value, specified as a finite double scalar value, in knots.
The Minimum tick value must be less than the Maximum tick value.
Maximum— Maximum tick mark value
Specify the maximum tick mark value, specified as a finite double scalar value, in knots.
The Maximum tick value must be greater than the Minimum tick value.
Scale Colors— Ranges of color bands
Ranges of color bands outside the scale, specified as a finite double scalar value. Specify the minimum and maximum color range to display on the gauge.
