AIR DEFENDER / REFERENCE

Which aircraft is that callsign?

Find a game callsign, then check the selected aircraft’s details before giving an order.

Game reference · v0.8.16.0Check ASSETS for the aircraft and resources available in your current session.

Four labels, four different jobs

What you readWhat it tells youWhat to do next
CallsignThe name used to follow a flight, sometimes with a number for a particular aircraft. A name is not a friendly identity decision.Select the contact and compare its Flight Info and track data.
Track serialThe system’s reference number for the track on your scope. It is not the number of passengers, the squawk or the aircraft type.Use the serial to keep the same track selected while checking its details.
Squawk / Mode 3 codeA transponder code associated with the aircraft’s reply. It is separate from the callsign and track serial.Read the squawk-code guide; do not infer an aircraft type from the code.
Aircraft type / ICAO type codeThe model or type entry, for example Boeing 737-800 / B738.Open Aircraft Data and match the full type before comparing specifications.

Find the aircraft, then look up its name

  1. Open TRACK LIST. Enter the visible callsign in Filter Callsign; use a distinctive part of the name if the full label includes a base prefix.
  2. Compare the matching rows. Check Track No as well as Callsign so you do not choose another aircraft with a similar name.
  3. Use the row’s > control to move the view to that aircraft. The locating marker helps you find it; this does not by itself confirm which contact an order will use.
  4. Left-click the located contact on the scope. If AC Control opens, choose the Flight Info tab. Compare its callsign and track serial with the row you intended before reading TYPE or giving an order.
  5. To find the callsign family below, search the name without the aircraft number: GAMECOCK finds GAMECOCK11. Looking up a family is separate from selecting a particular contact.

What do LUQ1 and the numbers mean?

A label such as LUQ1 GAMECOCK11 has more than one part. This is a format example, not a promise that this exact aircraft will be in your session.

Part of the exampleMeaning in the game
LUThe Leuchars base prefix. CY means Coningsby, LE means Leeming and LM means Lossiemouth. It does not give the aircraft’s current position.
Q1A Q number allocated to that interceptor. It is separate from the track serial and squawk. Do not treat it as the number of aircraft in a flight.
GAMECOCKThe allocated callsign name. Use this part to search the directory.
11The aircraft suffix within the allocated callsign. Keep the complete callsign when comparing aircraft; the suffix alone does not uniquely identify a track.

The game can show a base prefix without a Q number, for example LU GAMECOCK11. The Q form is used for a paired aircraft away from its base on a mission other than CAP. CAP means an air patrol. The base prefix alone is used in the other states. A Q prefix already allocated to a contact keeps its allocation, so it is not a live location report.

The listed callsign pools apply to game version v0.8.16.0.

Looking for a civilian flight?

BAW436 and SPEEDBIRD 436 can name the same flight. Learn which name to use, then compare its registration and Mode S address.

Check the whole flight

A name can be allocated again in a later session or appear in more than one pool. A number after the name helps distinguish aircraft; do not use it as the track serial. Select the contact, compare the callsign with Flight Info, then use the appropriate aircraft controls. Base-pool membership is a reference clue, not proof of the aircraft’s present location or identity.

Support callsign families

GADGET identifies the game’s Nimrod R1 callsign family. ALBERT is used for Hercules logistics and VORTEX for Chinook logistics. The AWACS allocation pool includes OVERLORD, MOONRAKER, SAURON and MAGIC 11–14. Confirm the aircraft in Flight Info before giving a task; the name does not replace its E or K identity or its type details.

Check the aircraft before choosing a task

These are examples of the game’s support callsigns. You do not need to have every example in your session.

  1. Search this directory for the name without its aircraft number: GADGET finds the family. To find a live aircraft, use its full callsign in TRACK LIST, compare Track No and use the row’s > control to locate it.
  2. Use these checks when the game is not asking you to click a target for an order. Left-click the intended track on the scope, outside the panels. If AC Control opens, choose Flight Info. Check the complete callsign and track serial, then read TYPE.
  3. For more type details, choose Aircraft Data. If TYPE says Unknown, you have not confirmed the model. Match the aircraft to the examples below before following its task guide.
Callsign exampleAircraft to checkWhat it does in the gameNext guide
GADGET01Nimrod R1Listens for radar emissions: signals sent out by other aircraft’s radars. It is a different sensor from AWACS.Launch and task the Nimrod
OVERLORD · MOONRAKER · SAURON · MAGIC 11E-3D Sentry AWACSProvides airborne radar reports through Link-11. Use the AWACS guide to check its reporting setup.Launch and position AWACS
ALBERT67Hercules C-130KMoves supplies such as fuel and weapons to an airfield. Follow the delivery guide to choose the load.Arrange a Hercules delivery
VORTEX01Chinook HC2A helicopter used to move supplies to an airfield. The name does not tell you which load it carries.Arrange a Chinook delivery

The digits distinguish a callsign from another in its family. They are not the track serial, squawk code, cargo quantity or number of aircraft. Keep the whole callsign when checking a live contact.

Does K mean the track is a Nimrod?

No. K is also used for other support aircraft, including tankers and transports. Compare the full callsign and TYPE; the letter alone does not confirm a Nimrod.

Compare Nimrod and AWACS

Can ALBERT or VORTEX refuel a fighter already flying?

Their SUP delivery moves supplies to an airfield. It does not transfer fuel to a fighter in the air. For that, use a tanker and the fighter’s REFUEL order.

Refuel a fighter in the air

Why names change between launches →

Additional fighter callsigns

The game can also use these names from its alternative fighter naming list in v0.8.16.0. The name alone does not tell you the aircraft’s base, position or identity.

  • PIRATE
  • SHADOW11
  • VIPER
  • FLASH
  • SIEGFRIED
  • BEANS
  • TOAST
  • WALLACE
  • GROMMETT
  • TARNISH
  • GUNFIGHTER

Search this directory with the name below. When selecting an aircraft in TRACK LIST, compare its complete displayed callsign and Track No, then check Flight Info before giving an order. Keep any numbers shown as part of that complete callsign.

Helicopter callsigns in the game

Civilian helicopters can use a service name or an offshore flight name. The entries below describe Air Defender v0.8.16.0; compare the complete callsign with the selected aircraft’s Flight Info.

POLICE · HELIMED

The game uses POLICE and HELIMED names for Bo 105 and AS355 Twin Squirrel helicopter traffic. Compare TYPE in Flight Info to find which aircraft you are looking at.

COASTGUARD

COASTGUARD names are used for S-61-type helicopter traffic. The S-61N also flies offshore routes in the game, so not every S-61N has a COASTGUARD callsign.

BHL · BND · BIH · KLH

BHL, BND, BIH and KLH are callsign prefixes for helicopter flights to offshore installations. Keep the following digits and any final letter when comparing the complete name. These are separate from Track No, the squawk and the aircraft type.

The digits are part of the callsign, not the track number or a position report.

Open TRACK LIST and compare the full Callsign and Track No. Use > to locate the aircraft, then left-click that contact on the scope. In AC Control, open Flight Info and compare its callsign and track number before reading TYPE or checking its route.

A service name can differ from the registration

For service-named VFR helicopters, the game can keep POLICE, HELIMED or COASTGUARD as the flight name while giving the aircraft a separate G- registration. A registration used as a callsign and a service-name callsign are different cases. Search the full flight name in TRACK LIST; use a registration or Mode S address for a register check when available. A generated name does not promise a matching entry in the civilian register.

Real-world reading: current UK callsigns

Today, UK radiotelephony uses HELIMED for helicopter emergency medical service (HEMS) flights and POLICE for police flights. Coastguard and search-and-rescue callsigns depend on the task. These current rules are separate from the game’s naming examples.
