The area between these full-scale needle deflections is what defines the course width.) An LDA approach (considered a non-precision approach) may have one or more marker beacons, perhaps a DME, and in rare instances a glide slope, just as other precision approaches have, such as ILS approaches. (At each "edge-of-course", commonly 1.5 or 3 degrees left and right of course, the transmitted signal is created in such a way as to ensure full-scale CDI needle deflection at and beyond these edges, so the pilot will never falsely believe they are intercepting the course outside of the actual course area. An LDA approach also is designed with a normal course width, which is typically 3 to 6 degrees. As a "directional aid", and only a Category I (CAT I) approach, rather than a full-fledged instrument landing system (ILS), the LDA is more commonly used to help the pilot safely reach a point near the runway environs, where he or she hopefully can see the runway, at which point he or she will proceed and land visually, as opposed to (for example) full Category III (CAT III) ILS systems that allow a pilot to fly, without visual references, very close to the runway surface (usually about 100 ft) depending on the exact equipment in the aircraft and on the ground.Īn LDA uses exactly the same equipment to create the course as a standard localizer used in ILS. Only circling minimums are published for offset angles greater than 30 degrees. Straight-in approaches may be published if the offset angle does not exceed 30 degrees. If the offset angle is greater than three degrees, the facility is classified as a localizer-type directional aid (LDA). If the angle of offset is three degrees or less, the facility is classified as an offset localizer. pointed or aimed) in such a way that the approach course it projects no longer lies along the extended runway centerline (which is the norm for non-offset and non-LDA localizer systems). In these cases, the localizer antenna array may be offset (i.e. It is used in places where, due to terrain and other factors, the localizer antenna array is not aligned with the runway it serves. A localizer type directional aid (LDA) or Instrument Guidance System (IGS) is a type of localizer-based instrument approach to an airport.
