Garmin's latest software upgrade for the GTN 650 and 750 includes visual approach guidance among a series of new functions.
The upgrade provides advisory vertical guidance in VMC, based on a published glide path angle or a 3o glideslope from the threshold of the runway, taking into account terrain and obstacle clearance.
Pilots can choose a landing runway and select vectors to intercept final, which will assist them in flying a stable approach. When a flight plan is loaded and an approach has not already been selected, the GTN will also provide a short cut to optionally load and activate a visual approach when the aircraft is within five miles of the destination airport.
Garmin believes the visual approach guidance capability will give pilots a more stable descent and precise flight path throughout the approach and landing whilst flying in visual conditions.
The new upgrade also includes LNAV approaches for airports without WAAS or SBAS, and ADS-B capability for aircraft equipped with TCAS II.
