2.1.1.25 Smart Glide™ Engine-Out Navigation
Smart Glide is designed to assist the pilot by enhancing situational awareness and providing helpful
automation during an emergency inoperative engine event. The G3X Touch is capable of providing this
assistance internally, without the need for an external navigator. Upon activation, Smart Glide assists the
pilot with three critical components of a safe recovery from an engine failure:
• If equipped with a compatible autopilot, provides flight director guidance to pitch for and hold best
glide airspeed
• Identifies and provides navigation guidance, as well as optional flight director guidance to a
suitable landing location (if one is available)
• Provides quick access to relevant communication channels and emergency checklists
When GSA 28 Smart Autopilot servos or other compatible autopilot is installed, the autopilot
automatically couples to the flight director guidance provided by Smart Glide, if sufficient altitude is
available. An optional discrete input can be programmed to provide a dedicated external panel mounted
switch for Glide Activation (Garmin p/n 011-05930-00).
2.1.1.26 Radar Altimeter and Radio AGL
Knowing precise height above the ground can be helpful to pilots during landings and flying in areas where
limited barometric altimeter setting information is available.
The Garmin GHA 15 uses radar technology to provide height above ground level (RAGL) information for
the G3X Touch. GHA 15 AGL data is available up to 500 feet AGL.
Alternatively, the G3X Touch system can receive Radar Altimeter AGL data from a connected radar
altimeter unit via ARINC 429.
Audible alerts based on radio AGL or radar altitude can be configured beginning at 300 feet AGL, and at
select intervals down to 1 foot AGL
