Display measurements for aircraft altitude
Aerospace Blockset / Flight Instruments
The Altimeter Indicator block displays the altitude above sea level in feet, also known as the pressure altitude. The block displays the altitude value with needles on a gauge and a numeric indicator.
The gauge has 10 major ticks. Within each major tick are five minor ticks. This gauge has three needles. Using the needles, the altimeter can display accurately only altitudes between 0 and 100,000 feet.
For the longest needle, an increment of a small tick represents 20 feet and a major tick represents 100 feet.
For the second longest needle, a minor tick represents 200 feet and a major tick represents 1,000 feet.
For the shortest needle a minor tick represents 2,000 feet and a major tick represents 10,000 feet.
For the numeric display, the block shows values as numeric characters between
0 and 9,999 feet. When the numeric display value reaches 10,000 feet, the gauge
displays the value as the remaining values below 10,000 feet. For example,
12,345 feet displays as 2,345 feet. When a value is less than 0 (below sea
level), the block displays
0. The needles show the
appropriate value except for when the value is below sea level or over 99999
feet. Below sea level, the needles set to
0, over 99,999, the
needles stay set at 99,999.
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.
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.
