ILS on HUD broken?

[SpecteRED]

I cant see any ILS symbology on HUD. No synthetic runway. I caught the ILS siglalnull

Do you have a waypoint (but) selected with the runway's (true) direction and glide slope programmed ?

Details

Assuming the ILS is transmitting.

1. If the landing waypoint was setup in the ME

• Select the landing waypoint (CP/PD will already have the Runway Heading and Glide Slope filled in)
• Contact ATC or check the mission briefing for the QFE and set the altimeter accordingly
• Set the ILS frequency (adjust ILS volume / check audio ID / HSI flags)*
• Set APP mode on the PCA
• Land using the ILS and HUD

HUD localiser guidance will appear with localiser signal and aircraft heading is within +/- 6° of Runway Heading

The HUD's Synthetic Runway will appear when BOTH localiser and glide slope signals are being received.

* if the runway's ILS is not working you will not have the HUD localiser/synthetic runway symbology

2. If the landing airport has not been set up in the ME

• Contact ATC and check which runway is active and it's QFE
• Set the ILS frequency (adjust ILS volume / check audio ID / HSI flags)*
• set the altimeter to QFE (ATC usually gives it in inHg, so you'll need a table to convert to mbar/hPa)
• Select the active waypoint you are going to use to land (1-20), it's co-ordinates are unimportant (say waypoint 19).
• PREP the waypoint runway info on the PCN (PREP 19 INS)
  • turn the PCN selector to CP/PD (RH/DS in the English cockpit)
  • enter the runway's true heading in the left field i.e. 179.0°T
  • enter the desired glide slope in the right field i.e. 3.0°
• Set APP mode on the PCA
• Land using ILS and the HUD

This is covered in Chuck's M-2000C Guide (Part 13 - Navigation & ILS Landing, Page 318)

thx, the runway's true heading was incorrect

Is there any way not to use the waypoint at the airfield, but to use TACAN instead? for example, I want to land at another airport not from my plan. and can I display the distances to TACAN on HUD?

The synthetic runway is drawn and scaled on the HUD using the height above the airfield (QFE), Glide Slope (PCN waypoint info), runway/ILS bearing (PCN waypoint info) AND that you are "on" the LOCALISER and/or GLIDE SLOPE signal.

It does not reference or use the waypoint's coordinates i.e. when landing at Vaziani (1500 ft MSL) if your altimeter isn't adjusted to QFE, the synthetic runway will be drawn smaller and further away as higher in glide slope --> greater distance from landing point.

No, TACAN does not have the Glide Slope and Runway Direction required or generate an ILS beam.

No, the radio navigation used in the M-2000C is backward compatible with earlier models - so can provide steering guidance to TACAN Offsets (VADs), etc. but these are limited to being functions of the HSI.

All good responses!

When approach symbols are missing, also check if you did not press the Palette SNA (Magic Slave, Designate, etc...) which in ILS approach mode declutters the HUD. Press again to get ILS back.
