How does ILS (Instrument landing system) work? I know it provides guidance to the runway by two signals, one modulated at 90 Hz, the other at 150 Hz, but how the airplane lock on those signals? Wh...
The ILS localizer is more sensitive than a VOR radial, therefore providing more accurate lateral guidance. The ILS has a glide slope providing vertical guidance.
Here is an example chart for KLAX ILS 25R approach. In the top right, it says the runway, the airport, and the approach type (ILS or LOC). In the top left, it says the ILS frequency, and just to the right, the runway heading. On the very bottom, there's a diagram of the glidepath. It lists the FAF, which is a "X" symbol with wide edges.
