These parameters define the different sections of the built-in cockpit display element. Not all displays use all these parameters, and each display will list the ones it uses in the descriptions provided.

If the display has any form of numeric display, the value units shown will depend on the display being set up - for example, a fuel gauge may use Gallons, while an Oil Temperature gauge may use degrees centigrade - however, a few displays have value units that are modifiable using the parameters in the [MISC] section.

All these parameters are 64bit floats, but the actual value you set should be appropriate for the display it pertains to.

This tells the simulation the type of cockpit that aircraft has, and will be used to assign an appropriate cubemap to be used for reflections when the glass material has been used. See the modeling page on Translucent Elements for more information.

Enum:

1. 0 - Open Cockpit
2. This is to be used if the rear of the cockpit is open to a cabin with windows visible from the cockpit.
4. 1 - Closed Cockpit
5. This is to be used if the rear of the cockpit is completely closed off.
7. 2 - Dome Cockpit
8. For dome-shaped windshields that go above the pilot, like the f16 or some single-seater propellers. Can also be used for open-air cockpits.
10. 3 - Helicopter cockpit
11. To be used for aircraft that have very windshields that can go down to the feet, covering the entire front of the aircraft.
13. 4 - Hot air balloon cockpit
14. Only for use with open air, hot air balloon cockpits/control areas.
16. 5 - Skyship cockpit
17. Only for use with a closed cabin, lighter than air aircraft (airships).

Integer:

1. 0 = none
2. 1 = Vacuum driven gyro
3. 2 = Electrically driven gyro

This parameter requires two values which define the system on which the turn indicators are dependent. The first value is for turn, the second for bank, and they should be set to one of the following values:

1. 0 = none
2. 1 = Vacuum driven gyro
3. 2 = Electrically driven gyro

For example:

turn_indicator.0 = 1,1

You can define multiple turn indicators where N starts at 0 and going up to number-of-indicators - 1.

List of Floats

Integer, one of:

1. 0 = None
2. 1 = Vacuum gyro
3. 2 = Electric gyro
4. 3 = Electro-mag slaved compass
5. 4 = Slaved to another indicator

or

List of 2 Integers:

1. type, slave_index

Integer:

1. 1 = Electric
2. 2 = Anemometer driven

This is a two value table used to define airspeed indicator N. The first parameter in the table is a scalar on the calibrated airspeed, and the second is an offset in Knots, where the offset is applied first, then the scalar. By default the value for the scalar is 1.0 and the offset is 0.0. This means that by default the indicated airspeed will be equal to calibrated airspeed.

There can be multiple entries for this parameter, one for each indicator, with N starting at 0 going up to number of indicators - 1.

List of Floats

When set to TRUE (1), this will instantiate an altimeter, which will operate independently of other altimeters, and can have failures applied to it. There can be multiple entries for this parameter, one for each altimeter, with N starting at 0 going up to number of altimeters - 1.

IMPORTANT! when referencing any altimeter using the appropriate SimVars (for example KOHLSMAN SETTING HG) the SimVar index starts at 1 not 0. So altimeter.0 is accessed by SimVar:1, altimeter.1 is SimVar:2, etc...

List of Floats

List of Floats

This sets up one or more variometers as part of the cockpit display. The parameter requires the following three values, given as a comma separated list:

• not used in Microsoft Flight Simulator 2024, should be 0
• static pressure derivation, in ft
• time constant that sets how quickly the value will reach it's target

For example:

variometer.0 = 0,0,4

List of Floats

Set the minimum throttle percentage for each detent and the corresponding name. For example, for the A320, level 1 is -100 REV, level 2 is 0 IDLE, etc...

Available names are:

1. "REV" - reverse
2. "IDLE" - idle
3. "A/THR" - auto
4. "CL" - climb
5. "FLX" - flex
6. "TOGA" - toga

Default level is 0.

Default name is "".

slats_level_1

to

slats_level_10

When this is set to 1 (TRUE) and the vcockpit_hud parameter is also set to 1 (TRUE), then a larger altitude HUD display will be used. This is designed for aircraft that can go above 99,999 meters.

This can be set to 1 (TRUE) to have a "vcockpit-style" digital external HUD, or it can be set to 0 (FALSE) to have a "steamgauge-style" analog external HUD. Note that many options will only have an effect on one or the other HUD type (these are flagged in their descriptions).

Default value is (FALSE).

This can be used to enable (1, TRUE) or disable (0, FALSE) using GPS for the altitude indicator instead of the indicated altitude value (based on air pressure).

NOTE: This option is only applicable when the vcockpit_hud is set to 1 (TRUE).Default value is 0 (FALSE).

When defining your aircraft, you can select this option to set custom colours for the airspeed indicator using local variables, meaning that these colours can be changed dynamically using the using the "L:" var identifier in Reverse Polish Notation.

For this to work you need to define specifically named local variables that target the appropriate colour ranges in the indicator:

L:HUD_AIRSPEED_WHITE_START    // corresponds to the "white_start" parameter
L:HUD_AIRSPEED_WHITE_END      // corresponds to the "white_end" parameter
L:HUD_AIRSPEED_GREEN_START    // corresponds to the "green_start" parameter
L:HUD_AIRSPEED_GREEN_END      // corresponds to the "green_end" parameter
L:HUD_AIRSPEED_YELLOW_START   // corresponds to the "yellow_start" parameter
L:HUD_AIRSPEED_YELLOW_END     // corresponds to the "yellow_end" parameter
L:HUD_AIRSPEED_RED_START      // corresponds to the "red_start" parameter
L:HUD_AIRSPEED_RED_END        // corresponds to the "red_end" parameter

NOTE: This option is only applicable when the vcockpit_hud is set to 1 (TRUE).

Default value is 0 (FALSE).

This parameter allows you to assign a custom variable to drive the visual representation of the throttle position in the HUD instead of the default SimVar GENERAL ENG THROTTLE LEVER POSITION. This is only really necessary if there is any visual lag between the HUD throttle marker and the user input, and the variable can be a Local Var (L: or L:1), an InputVar (B:), or some other SimVar. For example:

hud_engine_throttle_var = L:Virtual_Throttle_Lever_Pos

Note that if you do not include the hud_engine_throttle_var_indexed parameter, then the variable will be for all engines.

When this is set to 1 (TRUE) and the vcockpit_hud parameter to be set to 0 (FALSE). the the engine display will be replaced by power and RPM displays. These can be setup using the [HELICOPTER_POWER] and [HELICOPTER_ROTOR_RPM] sections.

Default value is 0 (FALSE).

This can be used to enabled (1, TRUE) or disable (0, FALSE) the navy-style AoA indicator. Requires hud_show_aoa to be set to 1 (TRUE) - otherwise the AoA indicator will not be displayed - as well as the vcockpit_hud parameter to be set to 1 (TRUE).

Default value is 0 (FALSE).

When set to 1 (TRUE) the HUD will display the AoA indicator.

Default value is 1 (TRUE).

When set to 1 (TRUE) the HUD will display the battery power indicator.

For examples and setup information, please see the [MANIFOLD_PRESSURE] and [RPM] sections (when the vcockpit_hud option is true both of these sections will be used, and when false only the [RPM] section is used).

Default value is 1 (TRUE).

When set to 1 (TRUE) the HUD will show the trim display.

Default value is 1 (TRUE).

When set to 1 (TRUE) the HUD will display the variometer, which can be customised using the [VARIOMETERS] section. Note that this is only used by gliders, and will only show 0 for all other aircraft.

NOTE: This option is only applicable when the vcockpit_hud is set to 0 (FALSE).Default value is 0 (FALSE).

When set to 1 (TRUE) a mach speed will always be displayed on the external HUD, and if set to 0 (FALSE), then it won't be displayed.

NOTE: This option is only applicable when the vcockpit_hud is set to 0 (FALSE).

Default value is 0 (FALSE).

Sets the offset (x, y, z) - in ft - relative to the model center for the physics simulation to be placed.

Default values are 0,0,0.

This defines the radius of curvature (bending) of the ball indicator tube. The value is in ft and must be greater than 0.

Default value is 0.8.

This defines the length of the tube arc (ball path). The value is in ft and must be greater than 0, but cannot be greater than \(\pi \times \text{radius}\).

Default value is 0.15.

This defines the tilt (pitch angle) of the ball indicator relative to the aircraft body frame, in degrees (between -180, +180). This value is primarily used to set the angle of the ball when the dashboard surface is not totally vertical. Note too that a value of 180 will give you a ball indicator for inverted flight (which is used in aerobatic aircraft).

Default value is 0.

This value is used to produce drag to slow the ball movement down, where the higher the value, the smoother (and slower) the ball will move.

Default value is 70.

This value is an exponential term used to modify the ball speed which makes the damping nonlinear (if set to a value other than 1).

Default value is 1.5.

This value is the time constant for the 2nd-order filter to smooth the local acceleration acting on the ball along the tube. The value is in seconds and must be greater than 0.

Default value is 0.05.
