RNAV (GPS) APPROACH KMEM Runway 36C

This video will show you how to set up and fly an RNAV (GPS) approach to LNAV minimums using VNAV. LNAV stands for Lateral Navigation. VNAV stands for Vertical Navigation. An LNAV is a non-precision approach to a MDA (Minimum Descent Altitude) and LNAV/VNAV is a precision approach to a DA (decision altitude). Any approach with a DA (decision altitude) is considered a precision approach. A LNAV/VNAV approach is a precision approach with a DA. You would set field elevation in the Altimeter setting window and press VNAV. This will provide a lateral and vertical path right down to the runway. If at the LNAV/VNAV approach minimums you don't have the runway in sight, you would make a "decision" to go around (missed approach). This decision normally means you will slightly dip below the minimum altitude which is why many (who use an approach button) will use a DDA (derived decision altitude) by adding 60' (some use 50') to the DA altitude as to not penetrate with minimum altitude for the approach. The G-IV only uses the approach button (APR) when flying an ILS approach. The G-IV does NOT use the approach button for LNAV/VNAV approaches so that doesn't apply here (however, the G550 does fly a LNAV/VNAV using the APR button). On the G-IV, we can either fly a LNAV/VNAV to a DA or a LNAV only approach to a MDA. A LNAV only approach is only using Lateral Navigation and is considered a NON-Precision approach and therefore has a MDA (Minimum Descent Altitude) with can NOT be penetrated even by an inch. Once you reach the MDA, you must not descent below that altitude. A MDA is a hard altitude. In this video we will show you how to fly a LNAV only approach , but use VNAV to get down the MDA. Using VNAV maximizes the benefits of automation. But unlike using the APR (approach mode) button which will fly right through the DA when activated, a LNAV/VNAV or LNAV (using VNAV) will level off at the altitude you set in the altitude window (i.e. approach minimum altitude). This video will show you how to set up and fly a LNAV approach to a MDA (a flight test requirement).
