Hey all,

I finally picked up a civ flight sim and I love it!! I have a few questions that I can't find the answers to, especially regarding the large jet panel MFD and ILS/VOR guidance.

1. Are there any guides for using the MFD? I have figured out the small Cessna ILS/VOR system and can land in 0 vis. However, I have flown many Vancouver to Seattle flights in a 777 and I still am real vague on the MFD symbology especially when it comes to ILS/VOR navigation. What color are the ILS localizer and glide slope?? The VOR line is the green one, right? Any help here please.

2. I take it that you don't (need to?) set an OBS with the avionics/MFD of the 777? I figured out how to use it to follow the desired course into SEA-TAC(161 deg) but is there something I am missing?

3. Lastly, an (Big Noob) ILS question. Take for example, SEA-TAC, is there only one way to approach with the ILS? Meaning: Can you come in from the south and land on 34 R using ILS or do you have to come around to the North and approach 16R to use ILS? Do any airports transmit the glide slope in multiple directions?

Thank you all in advance.

Jack

Go to the help section in the flight sim, you can find out a lot there. Which panel are you using by the way? Cause the ILS varies. Not by a lot, but it does. In the glass panels it's the pink vertical bar in that you have to keep centered between the top arrow and the bottom part. And the glide slope is the pink diamond, or whatever it is, that you have to keep on the centerline to stay on course. In some panels the VOR is the see-through bar with a green outline with an arrow at the front, or a green line with an arrow at the end. Don't think that the glideslope an be transmitted in opposite directions, otherwise you'd be landing right on the centre of the runway, it would have 2 glide slopes, but you only need 1 ILS freq.

Hope I helped,
Greg

If everything seems under control, you're just not going fast enough.

Greg,

Thanks, that cleared up some things. Another question...Do some ILS freqs just have a localizer and no glideslope? I have been trying to pick up the glide slope from both directions at Penticton B.C. and no dice. I get the localizer just fine with the pink diamond you described, but no glide slope. I tried many different altitudes to intersect and nothing comes up. Maybe I will try starting much farther out to the north. By the way, it is a great airport to attempt. It is GYYF just north of eastern Washington State. Thanks again.

the ILS should direct you down the glideslope i believe, if you are flying IFR flights and the ATC have given you the correct height to intercept it, then when you do it will cut your ALT hold button off and then direct your plane down the glideslope as long as your going the right approach speed aswell. no idea if that helped or not
