Overrides building and drawing of clouds as well as white-out-in-cloud effects

Overrides individual control surfaces, e.g. sim/flightmodel/controls/lail1def

Override DME distances

Overrides control of the refueling drogue. Write to sim/flightmodel/drogue to control

Overrides all engine calculations - write to prop LMN and g_nrml/side/axil.

Overrides all engine calculations - write to LMN and g_nrml/side/axil.

Override the autopilot's ESP/USP function.

Override FADEC temperature calculations. Setting this override allows you to write to ENGN_fadec_targets.

Override all parts of the flight system at once

Override flight director needles (both axes)

Override flight director needles (pitch only)

Override flight director needles (roll only)

Override the FMS going to the next waypoint.

Overrides all force calculations - write to LMN and g_nrml/side/axil.

Overrides fuel flow variable sim/flightmodel/engine/ENGN_FF_

Turns off transfer and dump and lets the plugin decide if the engine gets fuel

Override gear and brake status

Overrides all gear calculations - write to gear LMN and g_nrml/side/axil.

Override GPS computer

Override GPU voltage, for specifying custom GPU cart behavior

Override ground interactions (see sim/flightmodel/ground) - in v11 this was gone until 11.30.

Disable Austin's trucks.

Overrides groundspeed indication on GPS - groundspeed by default is a 2D speed, the pythag of movement in East and South axis. If you want something else, turn on this override and write to the indicator.

Overrides indicated airspeed dataref, so it is no longer update 1:1 from calibrated airspeed. Plugin can introduce installation error to indicated airspeed

Overrides engine temp vars sim/flightmodel/engine/ENGN_EGT_c and ENGN_ITT_c

Override control of the joystick deflections (overrides stick, yoke, pedals, keys, mouse, and auto-coordination)

Override just heading (yaw) control (disables auto-coordination). Use yoke_heading_ratio.

Override just heading (yaw) control for copilot input (disables auto-coordination). Use yoke_heading_ratio_copilot.

Override just pitch control. Use yoke_pitch_ratio.

Override just pitch control for copilot input. Use yoke_pitch_ratio_copilot.

Override just roll control. Use yoke_roll_ratio.

Override just roll control for copilot input. Use yoke_roll_ratio_copilot.

Override the mixture controls. Use ENGN_mixt to edit.

Lets third party add-ons turn off X-Plane's map layer that shows icons for other planes. This allows the plugin to supply their own custom map layer and not conflict with X-Plane. Only writeable by the plugin that has also set override_TCAS.

Override nav1 receiver

Override nav2 receiver

Override raw heading flown by nav (for GPS that fly by roll commands)

Override navcom radios

Override the sims crew and passenger oxygen system, so a plugin can control the oxygen system itself

Override partial control of a PFC jet cockpit (not for the faint at heart!)

Override the AI's control of the plane via the autopilot

Override position updates of this plane

Override the sims pressurization control, so a plugin can control cabin pressurization itself.

Override the prop mode. Use ENGN_propmode to edit.

Override the prop pitch. Use POINT_pitch_deg_use to edit.

Override slung load size calculation - makes sim/flightmodel/misc/jett_size writable.

Lets third party add-ons write to the TCAS source data array so you can have plugin controlled instances as TCAS targets. Only writeable by the plugin that has the AI planes acquired.

Override the throttles. Use ENGN_thro_use to control them.

Overrides the sim's time step. When enabled, xtim.prd_sim, sim/operation/misc/frame_rate_period is plugin-writable

Gives plugins control of sim/cockpit2/controls/left_brake_ratio and right_brake_ratio

Overrides all engine calculations but not the prop - write the torque your motor generates while the prop will still be simulated by X-Plane

Overrides and turns off X-plane's simulation of wake turbulence

Overrides the steering of individual gear from tiller/rudder.

Overrides all wing calculations - write to aero LMN and g_nrml/side/axil.

Controls whether the AI controls the user's plane

This used to be an option under equipment settings for auto damping or something.

Automatically coordinate tale rotor for helos

On engage, does the autopilot set itself to the current altitude?

On engage, does the autopilot set itself to the current heading?

On engage, does the autopilot set itself to the current speed?

On engage, does the autopilot set itself to the current vertical speed?

Muffle sound as if a headset is on

Do we have a panel for this angle? - Ben says, this actually indicated whether we had an old v6-style panel. Deprecated for v9, where v6 panels are not supported!

Are we in replay mode?

On crash, do we reset the AC to the nearest airport? - gone in v11, read only dref returns false for compatibility.

Start up on the ramp?

Start up with the plane running?

Show text ATC messages?

True if the user has enabled the experimental flight model. In 12.0 returns 0 because 12.0 does not have an experimental FM - may change in future versions.

Bitchin' Betty (should have been in /sound/)

Show text warning if framerate gets too low

Show text warning for otherwise hard to see things like carb-icing?

Warn if we exceed max g-forces on aircraft

Warn if we exceed max airframe speed

Warn if we exceed max flap extended speed

Warn if we exceed max gear deployed speed
