Revolutions Per Minute (RPM) Indicator

Display measurements for engine revolutions per minute (RPM) in percentage of RPM

  • Revolutions Per Minute (RPM) Indicator block

Aerospace Blockset / Flight Instruments


The RPM Indicator block displays measurements for engine revolutions per minute in percentage of RPM.

The range of values for RPM goes from 0 to 110 %. Minor ticks represent increments of 5 % RPM and major ticks represent increments of 10 % RPM.


To facilitate understanding and debugging your model, you can modify instrument block connections in your model during normal and accelerator mode simulations.

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.

Ranges of color bands on the outside of the scale, specified as a finite double, or scalar value. Specify the minimum and maximum color range to display on the gauge.

To add a new color, click +. To remove a color, click -.
