<Autopilot>

Defines options for the autopilot.

Properties

Scope	Inherits	Singleton	Optional
Global	No	Yes	Yes

Attributes

Name	Value	Optional (Default)	Description
alt‑sel‑compat	Boolean	Yes (true)	Whether the system should treat AP_ALT_VAR_SET key events as proxies for the INC/DEC events instead. This is required to obtain correct altitude select knob behavior when using ModelBehaviors that trigger SET events instead of INC/DEC events when the altitude select knob is turned. If your airplane uses ModelBehaviors that trigger the correct INC/DEC events, it is highly recommended to set this option to false.

<Group> (<VSpeeds>)

Defines a reference V-speed group. Each group can contain an arbitrary number of reference V-speeds.

V-speeds in all groups are user-configurable and appear in the PFD Timer/Ref menu, with each group having its own section. Each group has a unique name. The default group has a name equal to "" (the empty string). The ordering of the group tags in panel.xml determines the ordering of the groups in the Timer/Ref menu. The only exception to this rule is the default group, which always appears first.

The following image shows an example of the Timer/Ref menu when the aircraft is configured to include three default group V-speeds (left) and one "Takeoff" group V-speed (right):

If more than one <Group> tag with a given name is present, only the first tag in tree order will be used.

Content

A <Speed> tag or a numeric operator on <Speed> tags.

Default Value

None.

<Speed>

Defines an airspeed value. Can be used as the operand of a numeric operator.

The speed can be defined as one of several types, which determine now the numeric value of the speed is interpreted:

• Ias
  • Speed is equal to the numeric value as an indicated airspeed (knots).
• Mach
  • Speed is equal to the numeric value as a mach number.
• Tas
  • Speed is equal to the numeric value as a true airspeed (knots).
• Reference
  • Speed is equal to the sim reference speed as an indicated airspeed (knots).
• Aoa
  • Speed is equal to that which produces a normalized angle of attack (where zero-lift AoA = 0 and critical AoA = 1) equal to the numeric value. If AoA cannot be accurately related to airspeed (e.g. when the airplane is on the ground or when AoA data is not available), the speed will be undefined. It is up to individual consumers of the speed value to determine how to handle an undefined airspeed.

tip

Use numeric operators to define speeds with complex values. For example, we can define a speed equal to the maximum operating speed of an aircraft with Vmo = 175 knots and Mmo = 0.5 as:

<Min>
  <Speed type="Ias">175</Speed>
  <Speed type="Mach">0.5</Speed>
</Min>
