I've recently bought the Persian gulf map and been practising ILS landings with A-10C.

 

 

I've had difficulties with two airports so far

 

 

Sharjah rwy 303 111.95 Mhz works ok

Sharjah rwy 123 108.55 Mhz does not work - appears as no ILS signal

 

 

same with Al Minhad

 

 

Al Minhad rwy 270 110.75 Mhz works ok

al minhaf rwy 090 110.70 MHz does not work - appears as no ILS signal.

 

 

am I doing something wrong?

 

 

please.

To ensure the ILS switches direction correctly, have a +7 knot (+3.5 m/s) headwind for the runway you want to use ILS on.

 

Otherwise the 'active' ATC runway can be out of step with ILS and marker beacon direction for moderate headwinds.

tried and worked.

 

 

 

ahhhh the penny has dropped.

 

 

if i'm approaching an airport with zero wind I must land on the runway assigned by ATC. this I was not doing.

 

 

I assumed that both ILS signals were available on my request for landing.

 

 

I set up landing practice at airports for both directions where ILS was available for both directions.I just assumed I could just dial in the frequency and hey presto.

 

 

 

 

 

 

Thanks for your quick help. :)

Sorry to unearth an old'ish thread.

 

I have noticed the same problem regarding the ILS for Rwy 9 at Al Minhad. In my case though, ATC pointed me towards the rwy 9 because I'd set up easterly wind.

 

I'm not sure if it was above the required windspeed threshold, however, I don't buy this work-around because even with less wind, if ATC assigns a rwy to you and weather conditions makes it necessary to fly an ILS approach, the ILS signal needs to be turned on.

 

Is this some kind of coding problem?

 

Is this something I can hope is getting looked into since PG is a final released product?

I don't get what is your problem. Currently DCS ATC tells you what RWY is active and only that one is getting proper lights, NDBs and ILS. Do you suggest that IRL ILS signal always transmit both ways?

No, I ofc don't suggest that. Let me clarify what I meant.

 

Situation:

Approach Al Minhad

Wind from 85° at 4 m/s

Night time

Visibility low

ATC assigns rwy 09 to me for landing

 

The Problem:

 

The ILS signal is still not turned on or I'm not able to receive it. But I don't get what I could do wrong. I did alot of ILS approaches already. Right now, I fail to see the error on my side.

 

Did this clarify things?

Wookie, what aircraft have you tried it with? I'll check on my side.

Yes.

 

The A-10C's ILS (110.700 MHz) seemed to work ok for RWY 09 with a 8 kts headwind towards 265°T.

 

TACAN (99X) was a little strange as it gave distance but no course deviation until within 5-6 Nm of the runway threshold.

Yeah, it seems as if there is a wind threshold speed above which the ILS signal is turned on and below is not working, although it should work because ILS has nothing to do with the wind situation at the aifield.

There's a known bug in the 2.5.x Caucasus map where certain ATC and ILS directions desync for headwinds of 1-6 knots (0.5-3.2 m/s).

 

I haven't tested the PG's airfields and winds but it's something to be aware of when creating missions.

In the Viper, I cannot input ILS frequency 111.20 for RWY 13L at Al Dhafra AB. The DED just blinks as if there's an error with the frequency input. Is there another freq I should be using?

111.2 MHz is a VOR / VDB frequency.

So what's the ILS frequency for Rwy 13L at Al Dhafra AB?

Al Dhafra RWY 13L (126°M / 128°T)

ATC 126.500 MHz, 251.000 MHz

TACAN 96X

 

Mission Editor says RWY 13L ILS = 114.90 ??? MHz

 

F10 Airport Info says RWY 13 ILS = 111.20 (MMA) ???

 

Struggling to get the F-16's ILS to work at Al Dhafra ?

Map looks to be marked up wrong ?

Exactly. I haven't tried other AC yet though. I'll ask around the Viper thread.

Same in A-10C and Viper.

Neither of which is a valid ILS frequency, so there's definitely something wrong there.
