November 23, 200421 yr Tried landing 3 times on RWY 31 R in the SimFlyers KJFK - the Localizer keeps placing me .3 mile aff to the left. What is wrong? All the other runways seem to line up. Anyone have a solution? THanks.Chris Catalano
November 23, 200421 yr Hi ChrisI have Simflyers world airports, which includes JFK, and I don't have this problem. I have, however, switched the AFCAD to one that will work with Ultimate Traffic as I have it installed.Gary
November 24, 200421 yr "The real thing? Huh?"I don't know if it's true @ JFK, but some localizers are offset and you don't make a "straight in" approach. I believe the localizer guides you in to decision height, and then you make the final alignment with the runway. LGA has one such approach as well.-JohnEdit: Here's a useful link:http://www.airnav.comAirnav shows that rwy 22R is offset 2.5 degrees, but not 31R
November 24, 200421 yr Ummmm.No problem to my surprise. Straight in like an arrow.I do not believe this is quite correct either judging by the approach line shown on the FSNAV map. Looks like about a fifteen to twenty degree angle off of the right side to me. As someone has mentioned, this approach is probably offset for a realworld approach. Probably SimFlyer's last AFCAD offering made it an easy straight in approach.Happy flying:RTH
November 25, 200421 yr Many times an offset approach is at an airfield due to obstructions, can be even a hill or trees and buildings in the way of a straight in landing. JFK was built long after a lot of skyscrapers in NYC, so maybe they couldnt move them for straight in landings.
November 25, 200421 yr The approach plate that I have, which is admittedly old, show the runway heading as 314* and the locaiizer at 313*. Using the default scenery the localizer lines me up nicely with the runway. What heading are you flying on this approach (no wind please)?There is a NDB (268 KHz) at the outer marker (DME 5.2). Tune 268 and see if you are flying over the NDB as you follow the localizer. It sounds like a scenery or an AFCAD problem. R-
November 25, 200421 yr The ILS for 21 right at Felts Field in Spokane (KSFF) is like this in the real world, the localizer is off to the side rather than at the opposite end of the runway. This causes you to approach at an angle and it is for obstacle clearance as there are hills near the runway (recently a small cargo aircraft plowed into the hillside there in the fog about a mile or so short of final, sadly the pilot didn't survive). MSFS doesn't simulate this for KSFF and I've always wondered how I could get it to line up with the real world position.----------------------------------------------------------------John S.

November 25, 200421 yr >It sounds like a scenery or an AFCAD problem. Yes - I think that is what it was. DOn't have the problem anymore. Also, what would it look like on the approach plate if the localizer was offset? Would it actually TELL you this somehow?Thanks,Chris Catalano
November 26, 200421 yr Chris:Look at the number of degrees specified for your approach on the approach plate vs the Runway number.For example, my home airport is KLWB, you might want to take a peek at it. There is an offset of about 5 degrees. I know one of the runways at La Guardia also includes such an offset (Real world in both cases).One runway, 04/22 at KLWB. The ILS approach is on the 04 end. The degrees shown on the approach plate are 045 degrees which is just about correct for the offset. In fact, I just flew the approach and with no wind conditions I held 45 to 46 degrees for the approach. With a big bird, FS9 brings you in a bit too high and too far down the runway, but you will get the idea.Happy Flying:RTH
November 26, 200421 yr At runway 4 at KLGA, it heading is actually 44 degrees. Does this mean that the localizer is set 4 degrees to the right of the runway, or does it mean thet the runway itself is set to 44 degrees (which in that case, tuning the course selector to 44 degrees in my aircraft will align me perfectly with the runway?) Which is it actually? I always thought the runway number means that it can be anywhere within 10 degrees of its designation. Is this not true? Or is the runway ALWAYS alligned to a zero, and the localizer is at the offest?Very informative! Thanks so much!Chris Catalano
November 27, 200421 yr Chris:I think you are correct relative to plus or minus five degrees, but I am going to have to think about this for a while before I put both feet in my mouth. This easily explains how one can be four or five degess off from the runway number and yet have a perfect straight in approach (as your KLGA Runway 4 was for me @ 45 degrees). For an offset approach, an additional number of degrees off of the runway number would obviously have to be flown, possibly in the opposite direction which might even cancal out the heading/runway difference.I am not sure exactly how this is completely best explained at the moment without confusing the matter more than I probably already have.Particularly in FS9, I am also not sure whether magnetic variation is handled exactly as it is in the real world which will confuse an offset approach even more relative to what you will be reading on your DG. My assumption is that when you press your "Heading Indicator (Reset)" key that it does the same thing as setting your DG to match your compass reading (Or runway heading if you were on the ground), but of course there is no compass card in FS (to my knowledge).To really confuse the issue, in an old copy of the "Airman's Information Manual" under "Marking" in the "Airport, Air Navigation Lighting and Marking Aids" it states the following:"(Runway numbers and letters are determined from the approach direction. The number is the whole number nearest one-tenth the magnetic azimuth of the centerline of the runway, measured clockwise from the magnetic north.)"I'm not going to tell you how old my copy is, and hopefully there is a more simple definition given today.Happy flying:RTH
