Display measurements for aircraft airspeed

Description

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 VFE (maximum speed with flap extended) and VSO (stall speed with flap extended) accurately for aircraft airspeed and stall speed.

Parameters

Connection

Select a 1-element signal to connect to the block.

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

Specify the minimum tick mark value.

Default value is 40.

Specify this number as a finite, real, double, scalar value.

The Minimum tick value must be less than the Maximum tick value.

Maximum

Specify the maximum tick mark value.

Default value is 400.

Specify this number as a finite, real, double, scalar value.

The Minimum tick value must be greater than the  Maximum tick value.

Scale Colors

Specify ranges of color bands on the outside of the scale. Specify the minimum and maximum color range to display on the gauge.

Label

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.

Introduced in R2016a
