May 15, 201214 yr Thanks! When I set my nav1 radio to the desired freq (i.e. 110.10) I also set the nav2 radio to the same freq? I guess since this is a topic about ILS I have another question. Say Im between Lanai and Maui and want to get on the Maui ILS (I believe its 024 degrees and 115.1??) How do I go about that the correct way? I know I can always cheat and press M but would like to learn the proper way.
May 15, 201214 yr Thanks! When I set my nav1 radio to the desired freq (i.e. 110.10) I also set the nav2 radio to the same freq? No, you don't have to do that. You only use two VORs when you actually need them! No need to set them both to the same frequency. I guess since this is a topic about ILS I have another question. Say Im between Lanai and Maui and want to get on the Maui ILS (I believe its 024 degrees and 115.1??) How do I go about that the correct way? I know I can always cheat and press M but would like to learn the proper way. First of all: you are mixing up things. The Maui VOR (OGG) has a freq of 115.1, the ILS of Kaulai (IOGG) has a freq of 110.1 and a course of 024. This topic is about ILS indeed but you say you want to know how to get in front of the ILS without using the map and for that you need VOR! Maybe you should go through some VOR tutorials first which you can find in this topic: http://forum.avsim.n...-big-vor-topic/ I think that almost everything you need to know is in that topic.
May 15, 201214 yr No, you don't have to do that. True - you don't have to set it to the same freq... but it is a good idea (hopefully makes sense why below). If I were setting this up (ILS or LOC RWY 2 http://aeronav.faa.g...05/00762IL2.PDF)... I'd have 110.1 (I-OGG) dialed in as primary in both NAV1 and NAV2. Something happens to NAV1, I can revert to NAV2 to fly the LOC RWY 2 approach - "of course" I started timing at the FAF... and know that since I am flying the approach at 90kts, it will take 5:52 to the MAP (lower left of approach chart). In the Standby Windows... I think I would put 117.7 (LNY) in NAV1 and 115.1 (OGG) in NAV2. Both VOR Heads should have 24° as the selected OBS course. Although not necessary, 24° in NAV1 provides a 'reminder' of the Approach inbound course... and fortunately is the same as the initial course to be flown for the Missed Approach Procedure. I can use NAV2 then to initially navigate the procedure (Climb straight out to 3000' on the 24° radial, climbing right turn to the VOR, then R-190 radial outbound from OGG) then use NAV1 to navigate to, and fly the hold at CAMPS. First of all: you are mixing up things. Here's something desberardo, that may help you not to mix them up... ILS frequencies use the lower part of the frequency spectrum (LOC - low) from 108.0 to 112.0 (the VOR Band runs from 108.0 to 117.95)... also the ILS will use an ODD tenth... So you would see 115.1 and know right away it will be assigned to a VOR (it is above 112.0). The Kahului Localizer is 110.1 (odd tenth, correct lower band). I know... so much to pack into one's noodle... maybe it will be useful. -Rob O.
May 19, 201214 yr Here's something desberardo, that may help you not to mix them up... One BIG THING that I failed to mention here... the VOR ID's are just 3 letters... OGG for example. With the Localizer ID, you will see it prefixed with an "I"... I-OGG for example. And in the Profile View of an approach chart if it referencing DME mileage, you will see the number inside a "bullet" with the station it is referencing, for example: http://aeronav.faa.gov/d-tpp/1205/00762IL2.PDF CAMPS intersection is 17.5DME using I-OGG. TEBBS is 10DME using I-OGG (both using the DME paired with the Localizer... not the OGG VOR).
