Reading the scope / 4 MIN READ

How do I read the Aircraft Data tab?

Use Aircraft Data to understand the type listed for a contact. Use Flight Info to read the flight you have actually selected.

Open the right contact

  1. Left-click the contact. Check its callsign or track serial so you know which flight you are reading.
  2. Choose Flight Info. A player-controlled aircraft may open on AC Control first, so change tabs if necessary.
  3. Choose Aircraft Data in the same panel. Read the aircraft type at the top before comparing any numbers.
  4. Return to Flight Info for the selected contact’s current details. Follow the specification guide if a label or unit is unfamiliar.

Where does the type name come from?

The game can obtain a type from a flight declaration, visual identification by a pilot or electronic-warfare information. New identification information can change the displayed type. The type name is a piece of available information, not a guarantee that the whole contact has been identified correctly. Keep following the identification procedure.

Compare one contact carefully

  1. Confirm the callsign in Flight Info, or the track number on the scope data block. Note the current ALT, SPD and TYPE.
  2. Open Aircraft Data and read its heading and, when shown, ICAO CODE. Here ICAO CODE identifies an aircraft type; it is not a departure or destination airport code.
  3. Match the exact type or variant before using the reference. Read Cruise Speed, Max Speed and Service Ceiling using the specification explanations. These describe the type, not a command or current measurement.
  4. Return to Flight Info to compare the contact’s current flight. Look at its position and movement too; a catalogue number alone does not settle identity.
  5. If the Aircraft Data heading and Flight Info TYPE disagree, keep both names and values in your report. Do not silently choose whichever number fits your conclusion.

Why do some aircraft show different fields?

LayoutWhat it contains
Civilian register entryICAO CODE (the aircraft type code), ROLE, WEIGHT CLASS (a weight grouping), speed, ceiling, climb rate, range and PAX (typical passengers).
General aircraft referenceRole, category, manufacturer, typical crew, speed, ceiling, stall speed, typical range, powerplant and description.

The game looks for a matching civilian register entry first. If it does not find one, it uses the general aircraft reference. That is why every aircraft does not show an identical set of fields.

Does PAX tell me who is on board?

PAX means passengers. The register shows a typical passenger number for the type, not a live count of people on that flight. It shows CARGO where its entry has no positive typical passenger number. That label is not a list of what this particular aircraft is carrying. WEIGHT CLASS is a grouping, not a measurement of the aircraft’s current weight.

If the type is missing

The message No aircraft type identified for this contact. means that no type has been established for this display. Continue the identification checks. A blank type does not by itself make the aircraft hostile.

If it says CLASSIFIED

CLASSIFIED can mean that the reference data is unavailable. It is not proof that you have found an enemy or a secret aircraft. Read the accompanying message, compare the other track information and continue the identification procedure.

If the numbers do not agree

First check the type and variant, the field labels and the units. Current speed and maximum speed answer different questions. If two fields both claim to give the same kind of figure but disagree, record the contact, both labels and both values in a bug report. Do not explain every mismatch away as normal radar behaviour.

Use a clue, then check it

Unexpected performance is a reason to investigate, not a complete identity decision. Compare the available flight plan, ATC response, movement and identification evidence. A plausible number does not prove the claimed aircraft type either.

If new identification changes the name

After a visual-identification or EW report, recheck the selected contact and reopen Aircraft Data. Record the report, the TYPE in Flight Info and the Aircraft Data heading if they do not agree. A missing or different reference is a reason to check the data, not proof the aircraft changed type in flight.

Contact

Something detected or being followed on the display. You may still need to establish what it is.

Related guide: plot or track
Callsign

The name or letters and numbers used to refer to a flight in communications. Match it with the displayed aircraft before issuing an order.

Related guide: communications
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.

Related guide: trackblock
Track

The system’s record of a contact over time, built from related reports. On the scope it is shown using a symbol and available information.

Related guide: plot or track
Scope

The radar display: the map-like screen containing contacts, symbols and information.

Related guide: first session
Cruise speed

A speed used for the main travelling part of a flight. A reference cruise speed is different from a track’s current speed.

Related guide: interceptor speed
Service ceiling

The stated height an aircraft can climb to while still meeting specified performance requirements. The game’s reference figure is not its current height or a guarantee for every situation.

How to read aircraft specifications
Range

Distance. For a contact it means distance from a stated point; an aircraft’s range means how far it can fly under stated conditions.

Related guide: range bearing
Stall speed

A reference speed for the onset of a stall under specified conditions. A stall occurs when a wing or rotor blade exceeds its critical angle to the airflow and loses lift. It does not mean the engine has stopped.

How to read aircraft specifications
Powerplant

The engine or engines that power the aircraft.

How to read aircraft specifications
Flight plan

Information about an intended flight, such as its route and destination. Compare that plan with what the aircraft is actually doing.

Related guide: flight plans
ATC

Air traffic control: the service that manages aircraft traffic. In Air Defender, asking ATC can help you check a flight’s information.

Related guide: call atc
EW

Electronic warfare: using or responding to electromagnetic signals, such as radio and radar. In these guides, separate listening for signals from jamming them.
