Abaut Radio, aux, TACAN, ILS, etc… I need some help

[Juriarte]

Hello,

I don’t sure if my knowledge about radio systems are correct or not. Can you tell me if I’m correct?:

There are two radio system in the aircraft (F-16). The primary one (with VHF, UHF, ILS and TACAN) recorded in the computer and the AUX one (only UHF, TACAN and ILS). I can change from one to another one with a selector in the left panel.

If I choose standard one, I’m using the preselected frequencies in the flight computer. If I chose aux then i’m using the frequencies that I can change in the left panel (TACAN and UHF). Is this true?

The problem that I have is that if I play the landing training mission all its ok and I can comunicate with the control tower with the preselected frecuencies (without move to aux radio) but when I flight another mission (i.e. GPB o LGB) when I come back to my base I cannot communicate with the tower control. I’m tried switching from UHF to aux and moving all the wheels in the audio panel but if a press (t -1 o or another command) I don’t speak and I obviously I don’t have answer so I have to land without request the landing). I don’t know what I’m doing bad.

I have the same problem with ILS or TACAN I don’t know how to use the preselected ones.

Thanks for any help

Because each tower has its own frequency. Typically, presets 15-20 are classed as open which is why the majority use preset 15 to save the tower frequency. Presets are just that: 20 ‘slots’ to save SOP/Flight/Mission briefed communication frequencies to. It’s the same as your car radio. In the real jet, the backup presets can be changed too using a push button under the little flap above the MNL frequency dials.

Before each flight, you need to open the DTC window in the mission planner and scroll to preset 15 UHF and click Set Tower and Save. The training missions automatically load the DTC as part of the initial set up so you should be good to go.

For every other flight, you have to load the DTC via the DTE page on the MFD as part of the ramp procedure.

ILS and TACAN are much the same. On the T/ILS page on the ICP, you enter the 4 digit frequency ILS (xxx.x, you don’t type the .) and the TACAN. So unlike older versions of Falcon, and like the real thing, ILS and tower comms are unlinked. If you do it wrong, you could be trying to land at Kunsan, talking to Seoul tower, whilst following the ILS beacons of Kimpo etc., all whilst getting distance measurements from somewhere else again.

All frequencies and vital information are in the Airport Approach & Navigation Charts folder of the main Docs folder.

Check page 65 of TO-BMS1F-16CM-1.pdf document for the T/ILS page, and page 69 for COMM1 and COMM2.

The backup is only if you lose primary comms and navigation equipment. While on primary systems you can change the radio frequencies via the ICP. To change comm 1 click the comm button and input whichever freq you like. To change the tacan channel select the 1 button that says T-ILS. This will bring up the page that allows setup of the ILS system and tacan system. However tacan is only available via the HSI and you must select the tacan setting for the instrument.

Thanks. When should I use Com1 (UHF) and when Com2 (VHF)?

[Ironman53rd]

VHF - Between members of a flight or tune into another flight and or tower

UHF - tower and or other flight members or packages

GAURD - anyone who is in the air and listening irrespective of package or their UHF or VHF channels

@Ironman53rd:

VHF - Between members of a flight or tune into another flight and or tower

UHF - tower and or other flight members or packages

GAURD - anyone who is in the air and listening irrespective of package or their UHF or VHF channels

And for certain emergencies for GUARD?

GAURD - anyone who is in the air and listening irrespective of package or their UHF or VHF channels

GUARD - specifically, anyone who is monitoring 243.000 MHz. If your UHF is set to BOTH, then you are monitoring both your selected frequency and 243.000 MHz. If it is not in BOTH, but you have selected 243.00 then you will still hear transmissions on GUARD.

Use for emergency if unable to contact the desired agencies otherwise.

In BOTH, you cannot transmit on GUARD though if I’m right?

Now it works fine. Thanks.

Just one question. What are usually the frequencies set from 1 to 14 (I use 15 for the tower control) but I don’t know what other frequencies are useful.

I think I need:

• The tower frecuency.
• The AWACS one (in UHF or VHF?)
• Alternative airports
• Wingman frecuency (I think this is the VHF channel, it is’nt?

But the other ones?

Thanks

The 4 points listed are really only critical in MP as the AI (apart from Tower) will respond regardless of COMM tuning, however I recommend ‘simulating’ it anyway as good practice. All comms are listed in the manuals. Typically, intraflight (talking within your flight, so 11 talking to 12) would be done on VHF, Victor. You’ll notice presets 1-4 are titled Flight1, Flight2,…., and 5-8 are Package 1, Package 2,… I don’t what fixed rules are exactly but each VFS will have their own SOP also.

In the briefing, it saysto tune to preset 12 Uniform (UHF) for Tanker Comms, but the tanker will respond to you regardless, hence why it’s not critical in single player, only recommended for SOP and practice. The frequencies and COMM settings really come alive when flying MP

Page 74 of BMS-Manual.pdf explains the frequencies relative to the DTC. Page 91 (section 7.6) gives more depth on how it’s implemented and tied in with AI use.

@Planehazza:

In BOTH, you cannot transmit on GUARD though if I’m right?

Correct. The UHF radio set is one transceiver (transmit + receive) and one receiver (guard receive).

[Juriarte]

@Frederf:

Correct. The UHF radio set is one transceiver (transmit + receive) and one receiver (guard receive).

So if I configure the UHF in both mode and channel 15, im transmitting by channel 15 and receiving channels 15 and GUARD. Is’nt it?

[Cik]

yes
