![]() We don't recommend you do it, however, because you might end up placing a direct-to line on your map, leading to confusion about which course you're following to the runway. If you want GPS DME to match traditional DME on an ILS approach, you could type in "Direct IXXX" to get distances that match your approach chart. If you're flying IFR with an approved GPS, you can use GPS distance to substitute for DME.įor instance, if you're flying on an ILS and the DME for the FAF is 5 miles from the LOC antenna, and you're 2 miles away from the fix, your GPS DME will give you a 2 mile distance to the FAF. Thanks to GPS, pilots are using traditional DME less and less. If the equipment is overloaded by too many aircraft, those farthest away may not be able to pick up DME signals at all. Ground-based DME transmitters are also rated to handle roughly 100 aircraft at a time. IF the approach was correctly modelled in the sim, and you activated the approach, the Garmin would fly the DME arc for you.DME requires line-of-sight between the aircraft and the ground station, and terrain and distance beyond the horizon will prevent DME from working. So if you’re coming into VUPRI, you need to fly along the DME arc shown on the chart (10.7 NM DME arc) until you’re near ILPOX, and then you’ll get the ILS broadcast (both localizer and glide slope signals) and can follow it in to the airport. The fan is just there to give you a visual idea of the ILS coverage), and if you’re within range of the localizer transmitter, which you will be at IPOX. 'Dots out' may be a common measure pilots use to measure their tracking skills, but review the lateral displacements those dots. With a maximum one-quarter scale deflection maintained, the aircraft will be aligned with the runway, explains the Instrument Flying Handbook. Unlike a VOR which can be picked up from any angle (minus distance/interference issues), Localizers can only be picked up if you’re within the relatively narrow lateral broadcast area, identified by the small “fan” coming from the end of the runway toward ILPOX (the signal goes out further and a bit wider than the fan shown on the chart. On most localizer courses, full deflection indicates 2.5 degrees. You’re going to have to be near ILPOX to get a localizer/GS signal to show up. If you’re near VUPRI you won’t get a localizer signal since you’re nowhere near the narrow broadcast cone for a localizer signal. However, to clarify a couple of things about the approach and your comments. There’s definitely some issues with missing freqs and approaches in the sim for that airport. Procedures also go wack when this mismatch happens) This interface describes the geometry and the relationships of a localizer. For this reason the CJ couldn’t calculate my landing speeds, as it was unable to pull a runway 25 - at first I thought this was the problem, as I ran into this when landing on Easter Island. Aviation StandardsInterface ILcdLocalizer. (On a side note, this airport is one of the reasons I’m hopeful for World Hub - the runway is still 06-24 in the game, while procedures etc. ![]() I don’t know what could be causing this problem, and whether it’s my fault for misunderstanding something or an error in the scenery. It’s not an add-on issue either, as this behaviour persisted after disabling every one. Other systems had the same problem, too - I checked the Garmins 30, both only reported a single ILS available. On the VFR map, MSFS only gave the ILS 19 frequency. But, there was no glideslope when I turned on the relevant view in devmode. Having done that, I turned on dev mode and found that the ICAR localizer DOES exist, and broadcasts on 109.9, except for some reason it isn’t picked up as an ILS signal? There was even lateral and vertical guidance once I picked NAV1 as source. I waited until it was time to capture, at which point I switched to an LNAV/visual ad hoc procedure and landed. When coming close to VUPRI, I realized the localizer’s arrow didn’t show up on my PFD, unlike the CRR VOR after some struggle (I was flying CJ4, and used mouse in a bit of turbulence) I verified that the option was disabled despite the correct frequency being tuned in. ![]()
