GARMIN G1000 NXI

Pilots may, for example, choose to display SafeTaxi
on the HSI map while preparing flight plan information
on the MFD - or simultaneously display NEXRAD and
traffic on the HSI map and view on the MFD a variety
of other SiriusXM aviation weather products such as
lightning, storm cells and more.
Frye pointed out how Garmin's SurfaceWatch runway
monitoring technology provides visual and aural cues
to help prevent pilots from taking off and landing on a
taxiway, on a runway that is too short or on the wrong
runway based on performance data entered during
preflight, further aiding in situational awareness at a
It simply works great, showing the runway and,
using programmed data, can alert the pilot that too little
runway exists for an arrival or departure. The pilot
may also choose visual and audible runway distance
remaining annunciations to hear aural call-outs beginning
when runway remaining drops to 5,000 feet, continuing
through 500 feet remaining.
Nearing PNC, Frye maneuvered the King Air east
of the straight-in approach to Runway 17 to give the
VFR approach capabilities a true workout. The new
visual approach guidance Garmin integrated into G1000
NXi provides a pilot with safety-enhancing guidance
during visual flight conditions, based on a three-degree
glideslope from the threshold of the runway. Pilots
can specify the runway on which they have landing
clearance, set custom minimums, select vectors or
straight-in for the final approach intercept and fly a visual
approach coupled with the autopilot.
It's a coupled approach similar to flying an instrument
approach - but geared to VFR operations. Used regularly,
the VFR Approach function offers an extra hedge against
loss-of-control accidents - a continuing challenge in
The system smoothly and precisely intercepted the
final-approach path to Runway 17, rolled out precisely
aligned with the runway centerline, and continued
descending on the 3-degree glideslope selected.
The advantages during visual approaches include
a more stable and precise flight path throughout VFR
landings in visual meteorological conditions. The NXi's
autopilot flew the visual approach as smoothly and
precisely as it comes.
With a push of the Go-around button on the throttles,
the VFR Approach function smoothly pitched and added
power for a smooth, shallow climb, leaving Frye free to
work the radios, stow the landing gear and retract the
flaps and start us headed back to 1K1.
There's more. But space is precious - so we'll jump
to some other high points.
G1000 NXi: Ready for the
2020 ADS-B mandate
Garmin made the G1000 NXi ready to meet
upcoming airspace modernization initiatives by
providing the G1000 NXi package with a fully
integrated, rule-compliant Automatic Dependent
Surveillance-Broadcast Out solution - approved by both
the Federal Aviation Administration and the European
Aviation Safety Agency. And Garmin didn't neglect the
benefits and appeal of ADS-B In.
The G1000 NXi also supports the display of ADS-B
In benefits such as the subscription-free FIS-B weather
as well as Traffic Information System-Broadcast. The
FIS-B weather products include: NEXRAD, METARs,
TAFs, PIREPs, winds and temperatures aloft, NOTAMs,
AIRMETs and SIGMETs.
The traffic capabilities include Garmin-exclusive
features such as the company's patented TargetTrend
and TerminalTraffic to further enhance traffic
awareness. TargetTrend provides pilots with a more
intuitive method of judging target trajectories and
closure rates, while TerminalTraffic displays a
comprehensive picture of ADS-B equipped aircraft and
ground vehicles throughout the airport environment.
These ADS-B In benefits combine to give pilots
superior situational awareness tools throughout the
terminal and en route environments.
The NXi also can work with active-traffic systems in
concert with TIS-B.
And traffic can be overlaid in the usual lower-left
box on the PFD or, more conveniently, within the HSI
display. Ditto weather radar from FIS-B - within the
HSI or on the big MFD, or both.
The MFD's operation allows only one weather radar input,
allowing the pilot to choose FIS-B NEXRAD or an installed
weather-radar output - just not both at the same time.
