HUD
The speed in the HUD is calibrated airspeed per default, and always when gear is commanded down. It can be switched on the HUD control panel right of the flightstick.
- Current G force.
-
*symbol, meaning the HUD is sensor of interest (SOI).
- 'NAV' or 'ARM' depending on masterarm. But 'BRAKES' if parking brakes are on, and 'F 20 G' if --- gear is deployed, 'F' for flaps, '20' for 20 deg extended and 'G' for gears down.
- Mach number.
- Max G-Force number achieved. Can be reset using WARN RESET switch located on the ICP (center control panel with the number buttons on it).
- Selected weapon.
- Blinking FUEL if bingo fuel.
- Direction and distance to you from bullseye.
- AR XXXXX is the CARA radar altimeter altitude above ground.
- CARA ALOW.
- B XX.X is slant range to steerpoint. Callsign if masterarm.
- ETA to next steerpoint. TA XX if masterarm on, XX stand for 1000s ft of target altitude.
- 023>2 means 23 NM to next steerpoint number 2. F034.2 if masterarm on, means 34.2 NM in slant range to target.
- Type of target if masterarm on.
- LIMIT if Vne exceeded. Be careful, exceeding Vne has high chance of damaging the aircraft.
- NO RAD if the aircraft radar is off.
- FLY UP if collision with terrain is eminent.
- FUEL if bingo. This can be clicked away using WARN RESET switch located on the ICP (center control panel with the number buttons on it).
- WARN if a serious flight control issue is detected. This can be clicked away using WARN RESET switch located on the ICP (center control panel with the number buttons on it).
- Here DED DATA will be shown, if enabled. Or PFLD if that has been selected.
- HSI: To enable localizer in HUD turn the mode knob on centerpanel left of the HSI.
- EHSI: To enable localizer in HUD click the 'M' knob on centerpanel EHSI.
- It can show both glidepath and ILS, with vertical and horizontal lines.
- If a line is centered on the FPM and segmented it means it's invalid.
- If a line is not centered but segmented it means it's valid but out of range.
- If a line is not segmented, it's in range and valid.
- Keep the lines centered on the FPM to aim for the localizer beams.
These are located on left cockpit panel except DRIFT C/O which is on the ICP panel (below the HUD).
Can switch the HUD scale to show true or ground speed.
Can switch the HUD Velocity, Altitude and Heading scales off, the digital readouts will remain though.
Can switch off the ATTitude lines and/or the Flight Path Marker.
- RDR sets the altimeter scale to CARA whenever that is available.
- BARO sets the altimeter scale to barometric.
- AUTO sets the altimeter scale to thermometer CARA at low AGL and barometric at higher AGL.
Will show the DED display content onto the HUD.
Will copy the Pilot Fault List Display onto the HUD.
Drift cutoff will force flightpath marker and pitch ladder to stay in the middle of the HUD.
On left side the thermometer radar altitude scale is shown, it is only shown at low altitudes. It is currently around 0 ft, the T symbol at 500 ft is the CARA ALOW setting.
At top it is seen the magnetic heading is 145. The upper-left * means the HUD is Sensor of Interest, so you will need to switch SOI to move the radar cursor on the MFD. The horizon line is on the runway, that means the runway not level, but going upwards from us.
On left side the speed tape shows 4, that means 4 kt of wind since we are still. Upper left shown 1.0 G currently and mid-left 0.00 Mach and 1.0 G force maximum pulled. BRAKES tells us the parking brakes are on.
The big X and FLYUP text means we are about to hit the ground. The orange peel is showing, meaning we are in dogfight (DGFT) mode. NO RAD means our radar is in standby mode. On the right isde the empty rectangle means the CARA radar altimeter cannot measure our altitude due to our attitude. Our mach speed is 0.17 and current G is 0.3. The little C next to the speed scale means its calibrated airspeed its currently showing (default setting).
This time the rectangle has a number in it and AR, this means the CARA system, gives us a radar altitude of 11900 ft. There is also a small symbol in upper right side, that is the great circle steering cue, often shortened to the tadpole. It shows the direction to current steerpoint and follows the FPM up and down in the HUD. The FPM is located approx 3 degrees below the bore-cross, that is estimated by looking at the pitch ladder, so this means we are flying with 3 degs angle of attack (AoA or alpha).
On right lower side we see B 34.9, thats the slant (direct through the air, ignoring earth curvature) distance to the steerpoint in NM. 0.04 means we will be there in 4 minutes if we fly straight towards it at current speed. 34>1 means 34 NM to steerpoint number 1 (along the earths curvature). BRAKES means the parking brakes has been activated while in air, not so well done.
Here we have activated master-arm and cannon is selected. The funnel is called EEGS, read more about that in Weapons. Notice there is an R next to altitude tape, that denotes that I have set it to show radar altitude instead of barometric. At the bottom the data from the DED panel is showing, as I have set it to show on the HUD.
Here CCIP bombing aim is showing, when I release the bomb(s) they will hit where the round pipper is on the surface. Look at speed tape, is has a little G which means its in groundspeed. The ground collision X is forming too, so its soon time to pull up. DED data is still showing but on a different page.
The big circle is called ASEC, its shown when AIM-120 or AIM-7 is armed. There is a little arrow on it, that the targets aspect, its about 10 o'clock on the ASEC meaning he is flying towards our 4 o'clock. The square is the radar designation on the target. The diamond with the spikes is where the missiles seeker head is looking. The Air Shuttle.. is the callsign of the target, only shown when master arm is in SIM or ARM. 2 AMM means 2 advanced medium range missiles is selected (2 AIM-120).
Just left of the altitude tape there a Dynamic Launch Zone indicator (DLZ) that guides you to when to shoot, read more about that in Weapons.
