With X-Plane 11.50, plugins that display traffic in X-Plane, whether auto-generated or from an online multiplayer network, have to use the XPLMInstance API to draw these aircraft in X-Plane’s world. Drawing with XPLMInstance places the 3D object in the world, but does not actually tell X-Plane or other interested third parties, such as EFBs, about the existence of another aircraft in the airspace around the user. Various techniques have been used by authors, which are commonly known as “TCAS hack” that involve taking control of X-Plane AI aircraft, but not drawing them, by inhibiting drawing from a 3D callback. Some plugins also get around this by providing “invisible” aircraft to be moved by X-Plane. With Vulkan and Metal, the 3D callback that was previously used to change the AI plane count for the “TCAS hack” no longer works. It is therefore necessary to adopt the new TCAS override, which provides an official and compatible way to notify both X-Plane and third-party plugins of traffic.

override_TCAS: Existing datarefs made useful

The new supported and recommended variant of the “TCAS hack”, now called “TCAS override”, relies entirely on datarefs and existing XPLM functions, so it requires no SDK update. It uses the following, well known datarefs, simply expanded in array size:

sim/operation/override/override_TCAS int
sim/cockpit2/tcas/indicators/relative_bearing_degs float[64]
sim/cockpit2/tcas/indicators/relative_distance_mtrs float[64]
sim/cockpit2/tcas/indicators/relative_altitude_mtrs float[64]

Using the new TCAS override requires that the plugin does the following:

    1. Acquire the AI planes with XPLMAcquirePlanes – This should be done with a null pointer for the desired model paths, so it is fast. You should only call this when you are ready to supply planes right now. That is, an online network plugin should not acquire planes before it is actually connected to the network! Since acquiring planes with no model load is fast, this should be deferred until the user is actually connected to a server.
    2. Activate TCAS override by setting the sim/operation/override/override_TCAS dataref to 1. Only the plugin that has successfully acquired the AI planes can set this dataref!
    3. Tell X-Plane how many planes you want to fill in with TCAS override (up to 63) by calling XPLMSetActiveAircraftCount.
      Note that you will get to update all 19 multiplayer planes then, even if the user has a lower AI aircraft count setting. It is not necessary for the user to increase AI aircraft count or provide special models to be loaded as AI. In fact, TCAS override works even if the user has 0 AI planes configured.
    4. Assign each target a unique 24bit number between 1 and 16777215 and set it to sim/cockpit2/tcas/targets/modeS_id[N]. This will be the mode S ID of the target and is used to track your target even if you move it between slots.
    5. Tell X-Plane about the traffic targets by writing to the existing relative_bearing_degs, relative_distance_mtrs and relative_altitude_mtrs datarefs or to the new sim/cockpit2/tcas/targets/position/double/ datarefs. Only the plugin who has acquired the AI planes can write these datarefs!
    6. Optional: Fill in more information than just the position into the new sim/cockpit2/tcas/targets/position/ datarefs. This way, you can keep X-Plane and other plugins updated about the state of up to 63 other planes.
    7. Optional: Provide a map layer to the X-Plane map with icons for the planes you are providing. If you are doing that, set sim/operation/override/override_multiplayer_map_layer to 1 to stop X-Plane from drawing its own icons.
    8. If you have fewer targets than anticipated, you can simply stop writing the positional data to a target slot. X-Plane will forget the target (and forget its unique ID). There is no need to set a lower XPLMSetActiveAircraftCount because X-Plane will drop TCAS targets that haven’t been updated in 10 frames.
    9. When you are done providing traffic (the user has disconnected from the online network) set the override_TCAS dataref to 0 and call XPLMReleasePlanes. This will re-enable X-Plane traffic or allow other plugins, like a real world traffic provider, to then take over traffic from you. This will also re-enable the X-Plane default map behavior, so you will want to tear down your custom map layer as well!

This will allow X-Plane to display your traffic on X-Plane’s default navdisplays, the G1000, the map and IOS console and also disseminate the information via ADS-B output to external EFB apps like FlyQ and ForeFlight.

Plugins and cockpit displays using existing datarefs

Existing aircraft most likely require no changes to pick up 19 traffic targets injected by TCAS override, since they are synced to the multiplayer datarefs.

Many third party aircraft use the absolute position datarefs to find out about traffic around them and show it on their navdisplay. These datarefs

sim/multiplayer/position/planeN_x double N = 1..20
sim/multiplayer/position/planeN_y double N = 1..20
sim/multiplayer/position/planeN_z double N = 1..20

will be updated by X-Plane, when a traffic plugin is using TCAS override, along with the derived velocity vector for ADS-B out.
XPLMCountAircraft will return the number of TCAS targets actively updated in the last 10 frames by the plugin owning the override, regardless of the user setting for AI aircraft. Therefore, all instruments can display all aircraft that are being written to, without requiring the user to change any settings.

The same number is also available from the new dataref

sim/cockpit2/tcas/indicators/tcas_num_acf int

Third-party aircraft are also free to adopt the relative position datarefs to display traffic around them, since they now will be filled in with useful information by the traffic provider.

New datarefs

New plugins can use the new set of datarefs that is not limited to 19 planes, but instead supports 63 aircraft currently. It is advisable to query the array size of sim/cockpit2/tcas/targets/modeS_id to find out how many targets the current version of X-Plane supports. Note that index 0 is reserved for the user plane.

X-Plane does not infer any information from the mode-S ID, nor does it make any guarantees about the user plane’s mode-S ID, other than that it is unique in the session, and that it fits in 24bits. Traffic providers can set the MSB of the 32bit integer (i.e. the_modeS_id | 0x80000000) to indicate their 24bit ID is a “real” ID that corresponds to the actual airframe they are providing. You would do this if you are replaying real-life ADS-B data. By default, the MSB should not be set: in that case you must not use the mode-S ID to look up aircraft type, airline, livery or other such information. The user airplane is simply assigned a unique ID at random, so it might well be that the user is flying a 172 with a mode-S code that in the real world belongs to a 747. Only if your plugin has reliable information about the mode-S code of its traffic (replaying real world ADS-B data), you can assign real IDs rather than randomized ones and set the MSB. You must not assume other plugins or X-Plane assign IDs matching real world aircraft databases when they don’t set the MSB.

You can optionally also provide a 7-byte flight ID (tailnumber or flightnumber) for each target which is used to identify the target on the X-Plane map.

Which of the positional datarefs are writable depends on how you update your targets:

  • In relative mode (writing the relative bearing, distance and altitude) X-Plane will calculate the world position, derive the velocity, and estimate the body angles for you. This is useful if all you care for is a blip on the display with roughly accurate data. Do not write to the xyz positions in that case!
  • In absolute mode (writing the x/y/z coordinates) your plugin should also write the vx, vz, vy velocities and roll/pitch/yaw body angles, as X-Plane will not estimate them. X-Plane will then fill in the relative bearing and distance information for you, and derive hpath and vpath from your cartesian velocities. X-Plane will also fill in the lat/lon/elevation global coordinates. This is useful for applications that know a lot about the state of the other plane, such as when it comes from an online network. Do not write to the bearing/distance/relativealtitude datarefs in this case!

Relative vs absolute updating is a per-target property, so your plugin can update different targets in different modes if required. The last dataref you write wins.

Coordinate transformation

X-Plane will do the conversion from Cartesian coordinates to latitude, longitude and elevation for you.

To convert from Cartesian x/y/z to relative bearings, use a polar coordinate transformation, with

sim/flightmodel/position/local_x and local_z

as the origin and

sim/flightmodel/position/true_psi

as the polar axis, with the relative bearing counting clockwise as is usual in all cockpit indicators. Note that we use elevation (sim/flightmodel/position/elevation and sim/multiplayer/position/planeN_el) and not local_y to calculate the altitude difference! This is important for targets that are far away from the coordinate origin, as the earth curves away under the local tangent plane and elevation will be higher than y.

Map icons

X-Plane will update the map showing other planes. However, it cannot know what the appropriate icon for the plane type you are supplying would be. If you want to make meaningful icons, you can supply your own map layer and tell X-Plane to stop drawing generic icons by setting sim/operation/override/override_multiplayer_map_layer to 1. This override is automatically cancelled when you give up TCAS_override, so don’t forget to remove your map layer when you’re done providing traffic!

Plugin coordination

Since only one plugin can be providing the other planes at a time, it is important that plugins play nice with each other when it comes to deciding who gets to control the aircraft in the world. This is facilitated by the new plugin message XPLM_MSG_RELEASE_PLANES that is sent to a plugin owning the planes when another plugin requests them.

Playing nice starts with choosing the right time to call XPLMAcquirePlanes:
Do not call XPLMAcquirePlanes because you might at some point in the future maybe connect to some network. Do call XPLMAcquirePlanes only when the user actually decided to connect to the network.

Do register a callback with XPLMAcquirePlanes so that X-Plane can call you when another plugin gives up control over the planes.

Playing nicely requires receiving the XPLM_MSG_RELEASE_PLANES message and acting accordingly:
Do give up the planes if you are providing synthetic traffic and an online network now wants the planes. Traffic flown by humans should always take precedence over generated traffic. Do call XPLMReleasePlanes when appropriate.
Do not give up the planes to a synthetic traffic provider if you are currently connected to online flying, obviously.

Finally, give up the planes as soon as you no longer have a source. That is, if the user disconnects from their online flying network, do call XPLMReleasePlanes to give synthetic traffic providers a chance to provide AI traffic again.

For a full example, refer to the example plugin.
