Troubleshooting / 3 MIN READ

A track has disappeared. What should I check?

Check whether the track symbol is missing, only its numbers are hidden, or the view has moved. Then check fresh radar reports and whether the aircraft has landed.

What exactly disappeared?

What you can seeStart here
The symbol remains, but its text is missingCheck datablock visibility and solo display. A datablock is the text beside the symbol: its identity and flight information. Hiding it is not losing the aircraft.
Several contacts vanish after a filter changeCheck the identity include filters before changing sensor settings. A filter decides which identities the scope shows.
The map moves or the area leaves the screenCheck pan, zoom and follow. An aircraft outside the view has not necessarily left radar coverage.
The track flashes before it disappearsUse the faded-track checks. Flashing alone has other meanings too; read any emergency message or IDENT cue.
Your aircraft disappears after approaching a baseCheck ACTIVE OPS, ASMA and ASSETS at the actual landing base. Landed aircraft are no longer airborne tracks.

Restore the intended display

  1. In ASMA, click A/C once before using Delete. This clears any single-sortie restriction and lets the solo-mode confirmation appear. If ATC is selected, leaving it ends the current controller conversation. Press the default Delete and read the new ASMA message from that press. If it says TRACK DATA SOLO ON, press Delete again and confirm a new TRACK DATA SOLO OFF message. An old message is history, not the current setting. Turning solo off does not create new sensor reports. With no selected or hooked contact, the game refuses to turn solo on and sounds a warning instead of posting a confirmation. Continue with the other display checks.
  2. Check the identity bar. Right-click each active include filter to remove it. With none active, all identities are included. Do not left-click to change a track’s identity just to make it visible; see the filter instructions.
  3. If symbols remain but global datablocks were switched off, press the default X once and check the result. It toggles visibility; repeated presses hide and show them again. The default C changes Minimal/Full detail, which is a separate setting.
  4. If the camera is following a hooked contact, use the default Z to release follow and pan back to the intended area. The controls guide explains navigation.
  5. If a shortcut behaves differently, check Escape → SETTINGS → KEYBOARD and HELP → Controls. Your saved bindings can differ from these defaults.

If fresh reports stopped

A faded track lacks fresh reports. Check the ground sensor state, the covered area and nearby contacts. If the picture relies on AWACS, use the L11 and coverage checks. One contact losing updates and a whole region losing updates are different clues; neither alone proves a sensor was destroyed.

If the aircraft has landed

For your aircraft, follow fighter landing checks or support-aircraft landing checks. Look at the actual arrival base after DIVERT or RDP. An empty airborne list is not a complete count of aircraft stored at bases.

If you still cannot account for it

Retain the save and note time, track identity/serial, last position, sensor state, game version and last display command. Say whether only text disappeared or the symbol itself vanished. Include any ASMA message and whether nearby tracks were affected in the problem report. Disappearance alone does not prove destruction.

For a station awaiting repair or returning after an incident, use the offline and recovery checks. A cleared history trail, an off radar and a loss of fresh track reports are different observations.

A quiet screen does not answer every question

If you are waiting for something to happen, use the quiet-radar checks. They separate advancing game time, hidden tracks, normal event spacing, training and a loaded save before you restart.

AWACS

Airborne Warning and Control System: an aircraft carrying radar and control equipment. In this game, the E-3D Sentry provides the airborne radar picture.

Related guide: awacs coverage
Track serial

The reference number the game assigns to a track, such as 007. It is different from the aircraft’s four-digit squawk code.

Recovery

Bringing an aircraft back to a suitable airfield to land. It may return to its home base or land at another suitable airfield. Here, recovery does not mean repairing an aircraft or restoring a saved game.
