RNAV-23 Question

Recommended Posts

On my chart ( Toronto airport ) I noticed 2 identifications,namelyRNAV-23(GNSS) and ILS-23What are the differences between the two and how do I approach ?Thanks in advanceHerbert Werni

Hard to give a short, accurate answer. There is good information here if you want to do a bit of reading: http://www.navfltsm.addr.com/

What are the differences between the two
One is traditional ILS approach to rwy 23 another is RNAV (GPS) approach to the same runway. You may find it difficult to fly the latter one within confines of FSX unless you have something like F1 Mustang, simulation of GPS approaches is still in its infancy in FS. The subject of RNAV (GPS) approaches is very technical and there are many differnt approaches that fall under this category, without seeing the one in Toronto I can't be more specific.

Thanks for the explanation.Hubert Werni

An ILS approach provides vertical guidance in the form of a glide slope radio signal. When combined with appropriate runway marking and approach lighting it allows for a so-called precision approach, which allows descent to 200 ft or lower above the threshold without having a visual. Most RNAV(GNSS) approaches do not provide vertical guidance (at least using the default aircraft and GPS), and are termed non-precision requiring higher minimum altitudes. Typically the chart will show intermediate fixes which allow you to step down in altitude to the minimum allowed, which you would continue until getting a visual or reaching the missed approach point.scott s..
