Instrument landing system localizer off?
-
I noticed no one else seems to have had this problem but upon landing and intercepting of the glide slope and localizer, the localizer never seems to be aligned with the appropriate runway, I was wondering if this is a common problem or just with me?
-
Hi, mate. Did you put in the correct ILS frequency for the RWY you want to use for landing?
-
Just name the airport and the specific runway of the theater that you may have this issue.
Then we can help you to find out what is wrong ;).

This is one of the most detailed tutorials about TACAN and ILS navigation on falcon. It helped me a lot:
-
Heres a helpful tip, land visually. Ive tried repeatedly to land ILS and just get cross hairs in the hud and no needles and im on the base frequencies and tower is set in my data cartridge and loaded prior to take off every flight. Osan tower is there wen you take off on runway 32, which is great apart from its supposed to be runway 27, then when returning to it youll find the tower has moved while you were away and tells you as you fly toward the runway âYour out of my airspace, call back when your 30 miles outâ
Most campaign airstrips do it as well. So yes the TACAN and ILS are off on a lot of runways. Sorry normal service will be resumed once they have the HOTAS Cougars programming working right.
Just out of curiosity has anyone actually found Osan by tower calls?

Well, to be honest: this doesnât help at all and it wonât get you far if you if have to land IMC/IFR. The instruments are installed for a reason.

No they are not. Of course there is a slight deviation between the name of the runway and the actual localizer course (f.e. at Kunsan the actual course of runway 36 is 356 degrees). And yes the TACAN station is not directly located near the runway. Both of these aspects need to be considered when shooting an instrument approach - as in RL. But ILS loc and TACAN are not totally off in BMS.

Osan is where it should be - TCN 94X and 308.8 MHz UHF.
The video posted by cmviper is great. Here is another good one that contains a lot of useful information:
-
Remember that Tacan approaches are NON-presicion and not intended to be aligned. Actually that they are always so co located withthe field itself is unusual compared to rl.
Remember to set in both loc frq and final course in the T-ILS page ln your icp/ded. And switch mode switch to tcn/ils mode on your center console.
And yes Ive been able to fly heads down just looking on the center console on the cross, vvi and att and alt and land on the rwy using ils in bms.
So it is possible to land âblindâ. -

Youâve asked and been answered with regard to Osan previously. The problem is not Osan or BMS, but you or your modifications.
Same with ILS. Works perfectly if you use it correctly. Watch the vids above to learn âŚ. and this one, if youâd like, to see the result:
You setup and fly properly and you land exactly where youâre supposed to.

Might help: C:\Falcon BMS 4.32\Docs\Airport Approach & Navigation Charts
This document is a summary of all the airbases: C:\Falcon BMS 4.32\Docs\Airport Approach & Navigation Charts\Korean Volume BMS 1002.pdf
Itâs important to note that not all runways have localizers in both directions OR if dual runway, for both runways. For instance at Kimpo, you have localizers on both runways and in both directions:
@Kimpo:
109.9 (14L)
110.1 (14R)
108.3 (32L)
110.7 (32R)However, for example, at Seosan, just one:
@Seosan:
111.5 (02R)
Kunsan, 1 runway, both directions:
@Kunsan:
110.3 (18&36)
Same for Osan:
@Osan:
111.3 (09&27)
Also important to note is the exact heading of the Localizer. For instance at Kunsan, it is NOT 180* and 360*. Itâs 176* and 356* because that is the actual runway heading.

The pilot model made by Harpoon is very useful. It contain the informations about head navigations, frequences etc.
-
all ILS work in âdefaultâ Korea I test them often enough when I update the charts
as said above, use the charts and the tables and youâll be fineRwy32 for Osan?
=> Wild modding
Most campaign airstrips do it as well. So yes the TACAN and ILS are off on a lot of runways
airstrip donât have tacan or ILS

Sorry for the delay in getting back guys, the name of the airbase is seosan, the runway frequency is 111.5 and the runway in question is runway 200, I have flown military and sim aircraft for years ( FSX ) so I have a thorough understanding of navigation and navaids along with the HSI, that is why I was suprised that the localizer does not seem to align with the runway with all the information entered, what I am going to do is go thru each piece of advice listed in the messages recieved and see if there is something I am over looking and I will post any thing that I may be doing in error so others may view and learn from itâŚâŚthanks guys!

only Rwy 20R has an ILS
so if youâre trying to follow the ILS for RWY20L, it will be off as itâs meant to be on 20R
thatâs the only ILS for Seosan, all other runways are tacan non precision approaches -
you know, it might help to put the nav mode switch to the ILS position, this is what I have found that I was not doing, otherwise the ILS works just fine, just wanted to post this just in case anyone else makes the same mistake.
-
âput the nav mode switch to the ILS position, this is what I have found that I was not doingâ
Iâm really baffled here⌠seems to me⌠you donât even see the localizer and GS bars in the HUD till you move that switch??
What aircraft did you fly in the Military? -
Yes, that is true, the nav mode switch must be placed to the nav ILS position in order to bring up the glideslope and localizer, if it is for instance left in the tacan position the aircraft radio will be tuned to recieve signals from tacan stations be they air or ground and the glide slope bars will not display therefore causing the pilot to do what is called a non precision approach, I have never flown an aircraft in the military I am just familiar with how the navigational system operates on an aircraft.
-
You can also switch the âInstr Modeâ knob to the ILS/TCN and have indications of the LOC and GS! The difference between ILS/TCN and ILS/NAV is the infos about the navigation aid at HSI (bearing/DME), means if you will have infos for a TACAN station or for a GPS waypoint (steerpoint). But the functionality of your ILS is exactly the same at ILS/TCN and ILS/NAV ;).

Well⌠glad to see you have it sortedâŚ
I was a Tacan Technician (ground side) in the Marines⌠so have a special interest in that field. Also worked on Ground Controlled Approach radar systems, so after many years of seeing the view from an ATC controller as he/she guided a pilot down the cone, its a joy to experience the aircraft side of things, so I spend alot of time setting up ILS approaches⌠just for the fun of itEdit
Thanks for that neystratiou⌠will definitively play with both of those settings⌠-
I like the ILS/NAV better than ILS/TCN when doing heads down ILS approach. You have the setup a STPT on the runway. The HSI shows wind correction angle and range to runway. The heads down ILS LOC is a bitch in a crosswind. But you should cross reference the two displays.
Is substituting the HSI for the for the heads down ILS LOC âone of my funny tricksâ or is a realistic procedure?
-
I think you have a term mixup. HSI is the heads down instrument on the center pedestal between your knees.
