An Instrument Landing System (ILS) is a highly accurate radio signal navigation aid consisting of two antennas which transmit signals to receivers in the aircraft cockpit—a glide path tower located next to the runway at the northern end and a localiser antenna at the southern end.Click to see full answer. Similarly one may ask, what is ILS? Instrument Landing System Furthermore, how do I fly in ILS? To fly an ILS, you first align your aircraft with the runway, using the localizer as guidance. This is typically done by radar vectors from ATC, or with a procedure turn. You then fly toward the runway and intercept the glideslope from underneath, so you don’t intercept a false glideslope. In respect to this, how does the ILS work? The ILS works by sending 2 beams up from the landing runway, one telling the pilots if they or high or low and the other telling them if they are left or right of the runway centreline. The radio beam signals are interpreted by the aircraft’s computer systems and relay this information to the pilots.What are the 4 components of an ILS? The ILS Components Guidance information: the localizer and glide slope. Range information: the outer marker (OM) and the middle marker (MM) beacons. Visual information: approach lights, touchdown and centerline lights, runway lights.
