Can anyone advise if/how I can tune the nav aids so I can fly an NDB/DME or LLZ/DME only approach?. When I select the ILS freq to get the DME I also get the Glideslope. I should add that is in respect of the PMDG B747-400 on FS2004. It must be possible but how?Thanks

The best way is modifying the airport's AFCAD file or find another airport.However IIRC if you tune NAV 2 to the ILS and Nav 1 on the NDB/LLZ the captain's panel shouldn't have the glideslope, as I think NAV 2 is usually coupled to the copilot's displays. (assuming you're on raw data)

NDB/DME and LLZ/DME are different approach procedures and they calls as "non-precison" approach type.NDB/DME is basicly NDB (non directional beacon)navigation station based approach. Generally NDB approach makes with chronometres (for taking time). But if there is "DME" (distance measure equipment), you can also get help DME from involved stations. When you read the chart, you will see where you read DME from (VOR station). NDB/DME is combine with NDB and DME source.How you do ? read the chart carefully and follow "arrows" on layout and profile section. You have to come NDB station at published altitude. If you are high, you have to make HOLD over NDB station until descent designated altitude. After that, you have to leave from NDB designated outbound degree. In NDB/DME, there should be distance mark at the turning point. (In normally you have to fly with time).Very easy but you have to check NDB always (in ADF or in ND)LLZ/DME is looks like ILS but; if you see only LLZ, it means there is no "G/S=glideslope,glidepath" signal, there is onle runway center line signal(LLZ=Localizer). LLZ approach similiar with VOR approach but LLZ approach much stable than VOR approach becouse Localizer signal directly shown runway center line. DME is mean, you will get distance information like as making ILS DME approach. Thatswhy you have to follow careffuly published chart layout and profile. LLZ approaches generally applies offset approaches becouse there should be geographic obstacles . You can see a lot of LLZ approach in Norways. LLZ is takes you nearest point of airport and then you turn to runway as instructions on published chart (I'm telling basicly, in fact it is very detailed procedures)

Hi.Ignore it. I don't think you'd be using APR mode for an NDB approach.The correct altuitudes and steps for such an approach are written on the approach plate. The NDB/DME approach is just a bunch of checkpoints, headings and times. You'd be expected to follow them yourself or to program them into a flight computer. Either way, you would set the altitude manually (when flying or when programming).Regards,D

Thanks for the answers. I will have a proper read of them later. Perhaps I didn't make myself clear. I know how to fly a NPA such as an LLZ or NDB approach. In real life its something you very rarely do. But when I tune the nav aids on the B747 -400 PMDG FS2004 you put the frequency for the ILS into the FMC nav aids section in order to get the DME but of course you will also get the full ILS. I don't want to see the Localiser (if I am practicing NDB approaches) and the Glideslope. I just want the DME info. An NDB alone will not have DME info. Its not like a VOR which is co-located with DME. thanks

Hi 4star.Sorry. I misunderstood your question. I think Avantime is probably right in saying you'll have to change the ILS characteristics of the runway in the airport's afcad. Alternatively, if you can do it or find one, download a DME gauge and put it in a new panel for the 747-400, positioned over the display you want to keep hidden. That may work.Regards,D

My fault for not being clear. So its a case of failing the equipement on the ground. Ok- thats what would of happened in reality probably if you were flying this type of approach. Any idea how easy/how to fail a GS for an airport?

I don't know how to use ADE but this is how it's done on Lee Swordy's AFCAD editor: Open airportView -> show navaidsright click on the green ILS 'triangle'In the ILS properties, uncheck "Has glide slope"If you want DME on a seperate radio, do this:In the ILS properties, uncheck "Has DME"Insert -> VOR/DMEIn the VOR/DME properties, select "DME only" on the type drop down box

Learn to do it the professional way! That is to fly the published approach be it ILS NDB etc.,vololiberista

One of the most fun LLZ/DME approaches is to runway 27 at San Diego Lindbergh (KSAN). Definitely no glide slope information there. You have to descend based on the altitudes on the published approach, availabe here:http://204.108.4.16/d-tpp/1013/00373L27.PDFAdd a little cloud to you first attempt just to raise the bar a bit - there is a lot going on what with configuring the aircraft to land as you monitor altitude changes. On these types of approaches, I use a 2000/fpm descent rate instead of my usual 1800 ft/min. Plus, as if that was not enough, someone decided to build a parking garage inconveniently close the final approach / threshold. So if you're low in a heavy like the 747 400, you will tear off the rear bogies!

4-Star:An LLZ is a localizer approach, so I'm not sure why you would not want to see the localizer needle. Tuned properly, you always will. You should not see a Glideslope needle however, unless the approach is LLZ / ILS. Try the Localizer approach to San Diego KSAN runway 27, or the NDB approach (no GS or localizer) to Dubrovnik Cilipi LDDU runway 12 in rain and 1/2 mile visibility. That should give you what you're looking for.Cheers,
