TFX: by Digital Image Design

HUD (Heads Up Display) from TXX, 1993

SECTION FOUR
THE COCKPIT

Although some functions and instruments vary slightly between the three aircraft flown in TFX, the same generic cockpit is used throughout. In general, the cockpit utilizes the latest in Multi- Function Display technology for clear and concise information flow.

When designing a multi-billion dollar super jet, a great deal of time and effort is spent to house the pilot in a comfortable, electronic environment not congested with hundreds of individual unimportant instruments such as cigar lighters. The instruments show exactly what the pilot needs to know at any one given time. For example, designers made it possible for the Eurofighter 2000 pilot to concentrate on hostile threats and potential danger and not have to worry about flying the aircraft.

Within the cockpit the displays are arranged in appropriate functional groups including engines and other related systems (on the far left-hand side), electronic counter measures and avoidance systems (on the far right-hand side), and vital warnings for incoming missiles, onboard faults and so on (the top section).

The cockpit has a simple color coding system for the information displayed:

GREEN
The system is active and functional

YELLOW
Caution! The system has sustained slight damage

RED
The system is damaged beyond repair

ENGINE MANAGEMENT AND FLIGHT CONTROL SYSTEMS


AUTO PILOT FUNCTION LIGHT
Shows that the auto pilot is active. The number displayed next to the light shows the mode. For further details, see THE AUTO PILOT.

24-HOUR CLOCK
Shows the time expired or the local time of day. the cockpit (cont.)

ENGINE IGNITION LIGHTS
One for each engine. An engine is shut down when its light is red. Ignition has been achieved when the light is green. Note that if either light flashes or turns red, the engine is damaged and may shut down.

FUEL GAUGE
Shows the amount of remaining fuel in pounds. A yellow caution light means that less than 500 lbs of fuel remains. A red warning light and a message on the HUD means that the fuel level has fallen to a dangerous level - below 200 lbs.

RPM GAUGE
Shows the amount of engine thrust being applied. The RPM should not drop below 60 per cent while in flight. When afterburners have been activated, the RPM will be at 100 per cent.

AFTERBURNER STAGE LIGHTS
One for each increase in power (beware that afterburners consume vast amounts of fuel). Note that the F-117 does not have any afterburners.

INDICATOR PANEL

STALL INDICATOR
The light flashes when the aircraft is approaching a stall and stays on when the aircraft has stalled (it may be accompanied by an audio warning). To recover from a stall, increase your throttle and push the aircraft's nose down - or hit the Panic Recovery Button!

CONTROL PANEL
A status panel for four key systems: landing gear, auto pilot, wheel brake and arrester hook. The status of the respective systems are indicated by the following colors:

GREY
The system is inactive but functional.

GREEN
The system is active and functional.

YELLOW
Caution! The system has sustained slight damage.

RED
The system is damaged beyond repair.

MAIN CONSOLE

MASTER WARNING LIGHT
It only illuminates when an onboard function is damaged. Check the MFD Warning Panel to discover the specific problem.

MASTER CAUTION LIGHT
It only lights up when there are problems or faults which may be repaired while in flight. Check the MFD Warning Panel to discover the specific problem.

FIRE LIGHT
It lights up to show that one or both of the engines are on fire. Your best bet is to eject ASAP.

INTERNAL MESSAGES PANEL
Status information from your onboard computer is displayed here.

EXTERNAL MESSAGES PANEL
Communication from AWACS, Control Towers and so on is displayed here.

MASTER THREAT PANEL

LOCK
Lights up when an enemy radar has fixed a lock on your aircraft. Use ECM and chaff to attempt to break the lock.

LAUNCH
An instant alert to danger when an enemy missile is launched from within a range of approximately 30 miles (air-to-air) or 50 miles (air-to-ground).

INFRARED-GUIDED MISSILE WARNING
Lights up when an infrared-guided missile is heading for your aircraft.

RADAR-GUIDED MISSILE WARNING
Lights up when a radar-guided missile is heading for your aircraft.

THREAT LIGHT
Activates when any unidentified aircraft appears on your radar or within a certain range. Note that the radar does not need to be in air-to-air mode for the Threat Light to activate.

COUNTER MEASURES PANEL

ECM AND STEALTH INDICATOR Lights up to show that your aircraft's ECM or stealth systems are active. Note that only the F-22 and Eurofighter 2000 have the capability to become radar invisible.

CHAFF INDICATOR
All three aircraft have a maximum of 15 Chaff canisters.

DECOY FLARE INDICATOR
All three aircraft have a maximum of 15 Decoy Flare canisters.

For details of the HUD itself, see page 18.

BASIC HUD INFORMATION

AoA INDEXER
A fixed display showing the aircraft's angle of attack on approach to the runway for landing. The following lights provide specific information regarding your AoA:

TOP
Your AoA is too high because your airspeed is too low.

MIDDLE
Your AoA is good for landing.

BOTTOM
Your AoA is too low because your airspeed is too high.

UNDERCARRIAGE DISPLAY
The bottom light comes on when your aircraft's undercarriage is on the ground. The top light (NW) informs you that steering is now performed by the nose wheel of the aircraft so that the aircraft can taxi and manoeuvre on the runway.

THE MAP
The overview of your theater of operations is not shown on the cockpit but is always accessible. Information on any hostile aircraft your radar is currently tracking is shown on the right- hand side of the map. Your systems can track up to 10 hostile aircraft at once.

Press the M key to call up the Map.

RED
Enemy aircraft

RED WHITE FLASHING
Authorized enemy ground target

ORANGE
Mobile surface target, e.g., a ship or tank

GREEN
Friendly aircraft

BLUE
Friendly surface craft, e.g., a ship or a tank

BLUE WHITE FLASHING
Runway selected for landing

MULTI-FUNCTION DISPLAYS

Press 1 key to cycle through MFD1 Each aircraft has three MFDs which incorporate the following displays:

MASTER WARNING PANEL
Shows which of the main systems is currently operational and their current status.

GREEN
The system is active and functional.

YELLOW
Caution! The system has sustained slight damage.

RED
The system is damaged beyond repair.

MASTER WARNING PANEL ABBREVIATIONS
It certainly helps to know what the following abbreviations refer to when they appear.
  • ENL Left Engine
  • UC Undercarriage
  • ENR Right Engine
  • COM Communications
  • WEP Weapons
  • FLP Flap
  • FUE Fuel
  • HUD Head-Up Display

SYSTEMS DISPLAY
Provides current flight details including RPM, speed, altitude, fuel and possible range with the present fuel load.

WEAPONS DISPLAY
A diagrammatic overview of the aircraft's pylons and any weapons on them. Also shown is the type of each weapon, and which weapons are armed.

FORWARD LOOKING INFRARED VIEW
The FLIR shows a forward view through your laser target designator when it is not yet locked on to any ground-based object. When you lock on an object the display will automatically change to the DLIR.

DOWNWARD LOOKING INFRARED VIEW
The DLIR shows the target locked on to by the laser designator. For further details see USING THE LASER TARGET DESIGNATOR on page 38.

GROUND TARGET DATA BANK
Shows your target and its distance from your present point in an air-to-ground mission.

Press the N key to switch between target views.

MULTI-FUNCTION DISPLAY RADARS

Press 2 key to cycle through MFD2

The TFX aircraft are fitted with the latest Westinghouse multi- role radar with variable scan and track modes including air-to- air and air-to-ground, and a map display. The symbology remains the same in all modes.

Activating the radars will break Stealth mode if it is operational, so don't activate your radars if you wish to remain invisible to enemy radar. The only 'safe' radar is the moving map display which uses a passive radar system which does not scan and emit any signal - it only receives information. "
