The back-course marker, where installed, indicates the back-course FAF. It indicates the point at which an aircraft is at the decision height on the glide path during a Category II ILS approach. The inner marker (IM), where installed, is located on the front course between the MM and the landing threshold.

The system provides no vertical guidance for approaches on the back course. Unlike the localizer, the glide-slope transmitter radiates signals only in the direction of the final approach on the front course.At locations where standard minimum obstruction clearance cannot be obtained with the normal maximum glide-slope angle, the glide-slope equipment is displaced farther from the approach end of the runway if the length of the runway permits or, the glideslope angle may be increased up to 4°. The glide-slope projection angle is normally adjusted to 2.5° to 3.5° above horizontal, so it intersects the MM at about 200 feet and the OM at about 1,400 feet above the runway elevation. The course projected by the glide-slope equipment is essentially the same as would be generated by a localizer operating on its side.The glide-slope equipment is housed in a building approximately 750 to 1,250 feet down the runway from the approach end of the runway, and between 400 and 600 feet to one side of the centerline.The glide path is the straight, sloped line the aircraft should fly in its descent from where the glide slope intersects the altitude used for approaching the FAF, to the runway touchdown zone. Glide Slope. Glide slope (GS) describes the systems that generate, receive, and indicate the ground facility radiation pattern.With no more than one-quarter scale deflection maintained, the aircraft will be aligned with the runway. This sensitivity permits accurate orientation to the landing runway. With this course width, a full-scale deflection shows when the aircraft is 2.5° to either side of the centerline. The localizer course is very narrow, normally 5°.The DME stops as you cross the thresholdīuild Version # when you first started experiencing this issue:.

Fly past the runway threshold at an airport with an ILS only at one end but with no back-course (e.The correct function should be the DME element works throughout 360 degrees as it broadcast on a separate but linked frequency to the ILS.ĭetail steps to reproduce the issue encountered: Humberside even includes a DME arc based off an ILS DME which is impossible to fly in the sim using Navigraph navdata: Examples would include Southampton (EGHI) and Humberside (EGNJ). This is an issue in the UK at least because generally missed approaches will use the ILS DME and we also we have some airports that have an ILS only to one runway end but use the associated DME in an NDB/DME approach to the other end. it only works in the front-course 180 degree arc). An issue with this is it affects the function of any associated ILS DME.įor ILS without a back-course the associated DME stops working once you’ve crossed the runway threshold (ie. When using Navigraph navigation data ILS are updated to correctly transmit/block the back-course depending on real installation specifics (for example in the UK, ILS do not transmit back-courses).
