![]() This is because the default aircraft do not have autoland, and 200 feet is generally the minimum altitude in which a pilot should be able to see the runway in a category I approach (may vary slightly depending on locale). One thing to keep in mind, especially if you are flying the default Airbus, is that you should disconnect the autopilot around or at least 200 feet and land manually. Why press LOC first? Because it prevents your aircraft from doing crazy things in case of a false glideslope (erroneous readings that you will never get in FSX, and which one would likely not get if intercepting below the glide slope in the first place). LOC allows the autopilot to maintain a lateral track to the runway only, while Approach mode does that and picks up the glide slope. You do not have to wait for the glide slope to come down before pressing the Approach mode, although some pilots suggest pressing LOC first when intercepting an ILS, followed by the approach mode afterwards once the localizer is intercepted. Once the autopilot picks up the localizer, it will disengage heading hold automatically, and once the glide slope centers, it will initiate a descent. Typically in real life, this is pressed when ATC "clears" us for the approach. But you should press the Approach mode button on your autopilot panel (FCU) before you intercept the localiser. If you are flying on autopilot, you CAN leave the heading hold/select right where it is at provided you are intercepting the ILS at an appropriate angle (one normally does if getting ATC vectored). After that, you fly the needles down towards the runway. ![]() Your localiser (tells you your horizontal deviation from runway track) should come in first, and then the glide slope bug should come down after that. If you have default ATC on, you will normally be "vectored"/directed on intercepting the ILS localizer, provided one exists at the airport and runway you are landing on.īasically, what is supposed to happen is that you will cut in on the approach path at an angle, and below the glide slope. 2500 feet above field elevation generally works splended, but if you want to be right on your descent profile, you should be about 3000 feet at 10 miles. You want to cut in at about 45 degrees (usually 30 works nicely), and about 10 miles out. You tune in the runway's localizer frequency and course, and then need to intercept the localiser beam at a certain angle.ĪPUtech is pretty close in describing how to approach. I don't know much about the default airbus (I normally tinker around with the aerosoft version), but the concepts should be relatively the same. If I left anything out, please let me know maybe another pilot will chime in with their sugestions. ![]() Remember to press the APP button *only* when the GlideSlope bug starts trending downward. If you're familiar with default Garmin GPS you'll discover how to get rwy frequency information by fiddling with it or by reading about its use in the Learning Center. You'll be shown the rwys' headings, surface type, length, and corresponding ILS frequencies and their rwy magnetic headings.Īnother way is by using the GPS that method is a bit lengthy to explain, though. ![]() If you need the rwy's ILS NAV 1 frequency and rwy's magnetic heading that you set your course to, one way is to go to the map, and click on your desired airport. Double-check that the NAV/LOC button is *on* in your AP. I already have my CRS set to the rwy's magnetic heading, my NAV 1 set to the rwy frequency, and if I've been navigating via GPS, switch it off (usually) between 10-15 nm out, so that the Nav 1 radio can track and align itself with the rwy. I usually get lined up (terrain permitting) as far out as 20nm from the airport, but make sure that I'm at about 3000ft within 10nm of the airport at about 210kts, slowing to final aproach speed (roughly 140-160kts, depending on the jet's recommended approach speed) at 4-6 nm from the runway threshold. You can intercept the ILS signal at up to 45 deg or less preferably no less than about 10nm from the airport, but a straight-line intercept works too. ![]()
