# uiaerohorizon

Create artificial horizon component

## Description

example

horizon = uiaerohorizon creates an artificial horizon in a new figure. MATLAB® calls the uifigure function to create the figure.

The artificial horizon represents aircraft attitude relative to horizon and displays roll and pitch in degrees:

• Values for roll cannot exceed +/– 90 degrees.

• Values for pitch cannot exceed +/– 30 degrees.

If the values exceed the maximum values, the gauge maximum and minimum values do not change.

Changes in roll value affect the gauge semicircles and the ticks located on the black arc turn accordingly. Changes in pitch value affect the scales and the distribution of the semicircles.

Note

Use this function only with figures created using the uifigure function. Apps created using GUIDE or the figure function do not support flight instrument components.

example

horizon = uiaerohorizon(parent) specifies the object in which to create the artificial horizon.

horizon = uiaerohorizon( ___ ,Name,Value) specifies artificial horizon properties using one or more Name,Value pair arguments. Use this option with any of the input argument combinations in the previous syntaxes.

## Examples

collapse all

Create an artificial horizon component named horizon. By default, the function creates a uifigure object for the indicator object.

horizon = uiaerohorizon
horizon =

ArtificialHorizon ([0  0]) with properties:

Pitch: 0
Roll: 0
Position: [100 100 120 120]

Show all properties

Create a figure window to contain the artificial horizon component, then create an artificial horizon component named horizon.

f = uifigure;
egt = uiaeroegt(f)
horizon =

ArtificialHorizon ([0  0]) with properties:

Pitch: 0
Roll: 0
Position: [100 100 120 120]

## Input Arguments

collapse all

Parent container, specified as a Figure object created using the uifigure function or one of its child containers: Tab, Panel, ButtonGroup, or GridLayout. If you do not specify a parent container, MATLAB calls the uifigure function to create a new Figure object that serves as the parent container.

### Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

## Output Arguments

collapse all

Artificial horizon component, returned as an object.
