NOTE: Navigation is provided for fixed wing aircraft above 30 kts and for
rotorcraft above 10 kts.
NOTE: The Chart feature provides a digital representation of a paper
chart and provides no vertical or lateral course guidance. Flight Plan and
Procedures are separate from Charts, and do provide vertical and lateral
course guidance for the loaded route or procedure shown on the Flight
Plan page. The term “Chart Unavailable” means that the chart cannot be
viewed on the Charts due to either a chart not being published, or an error
in the Chart database, but does not preclude its availability or inclusion of
the procedure in the Flight Plan or Procedures portion of the system. The
absence of a chart for a particular Departure, Arrival, or Approach does
not preclude its availability or inclusion in the Flight Plan or Procedures
portion of the system. The absence of a particular Departure, Arrival, or
Approach under the Flight Plan or Procedures portion of the system does
not preclude the ability to view the Chart for that procedure under the
Chart feature.

Creating a Parallel Track Pattern
The Parallel Track SAR pattern starts at the initial waypoint and follows the
initial track for the length of the first parallel track leg. A 90° turn in the initial
turn direction leads to the spacing leg with a length equal to the track spacing.
Another 90° turn leads to the second parallel track leg. The turns at the end
of the second parallel track leg are in the opposite direction as the previous
parallel track leg. The parallel track pattern terminates once the desired number
of parallel track legs have been flown.

Approaches with Procedure Turns
The procedure turn portion of an approach is stored as one of the legs of
the approach. For this reason, the GTN 7XX unit requires no special operations
from the pilot — other than flying the procedure turn itself — beyond what is
required for any other type of approach. Roll steering is provided to aircraft with
compatible autopilots.

Flying the Missed Approach
Upon reaching the Missed Approach Point, the GTN 7XX unit continues to
give guidance along an extension of the final course segment (FAF to MAP) until
you manually initiate the missed approach procedure (as mentioned previously
in reference to the “SUSP” advisory).
NOTE: If the unit is not configured for a CDI key, then the “activate GPS missed
approach” will only resume automatic waypoint sequencing. The user must
switch to GPS navigation, if desired, by using their external source selection
method (this is typical an EFIS system).

7. As you cross the FAF, the destination sequences to the MAP
(e.g. “RW31”, the runway threshold). With the needle on the
external CDI (or HSI) centered, fly toward the MAP, observing
the altitude minimums published on the approach plate.
8. When viewing the Map Page, you’ll note that the final course
segment is displayed in magenta (the active leg of the flight
plan always appears in magenta).
9. As you approach the MAP, a waypoint message appears on
the bottom of the screen.
10. Once the unit crosses the MAP (defined as the runway end
waypoint), sequencing will be suspended. Prepare the aircraft
for missed approach operation. Touch the Unsuspend key to
sequence to the Missed Approach procedure.
11. Fly the guidance provided by the unit to the MAHP and hold.
6.12.2
An LP approach is flown similarly to an LNAV approach, except the precision
is greater as it utilizes the SBAS accuracy. It has similar lateral accuracy as an LPV
approach. Angular scaling is similar to a localizer approach. Most LP approaches
have step down altitudes associated with them. The approach still results in an
MDA and missed approach point.
If the approach is indicated as LP +V, advisory vertical guidance will be
provided. This does not change how the approach should be flown, and the
pilot is still responsible for descending to the correct altitude at each step down.
The approach still results in an MDA and missed approach point.
1. Within 30 NM of the destination, the GTN switches from en
route mode to terminal mode and the CDI scale transitions
from 2.0 to 1.0 NM, full scale deflection.
2. As you approach the IAF, a turn direction message appears on
the bottom of the screen.
3. As the distance (DIST) to the IAF approaches zero, the message
is replaced by a time to turn advisory that counts down 10
seconds prior to the turn.
4. As you approach the FAF, the GTN will begin to automatically
rescale in an angular fashion. This will allow the LP approach to
be flown in the same fashion as a standard localizer approach.
At 2.0 NM from the FAF, CDI scaling is tightened from up to
either 2° or 0.3 NM, full scale deflection, whichever is smaller.

5. Sixty seconds prior to reaching the FAF, the GTN will check
the required Horizontal Alarm Limit (HAL) to ensure the GPS
position integrity is within limits to complete the LP nonprecision approach. In the event the HAL limits are exceeded,
the approach will be downgraded, when available, indicated
by “LNAV” on the moving map, otherwise the approach
will be aborted. A message will note that the approach is
downgraded and the NAV indicator will be flagged until the
message is viewed. You may continue the approach using
LNAV non-precision minimums if there are LNAV minimums
for this approach. In the rare event the GPS HAL limits cannot
meet non-precision limits, the GTN will notify the pilot with
a message to abort the approach. The GTN will revert to
terminal limits of 1.0 NM to support navigation to the missed
approach. If the approach is indicating an LP +V, it is possible
that the advisory vertical guidance could be removed without
annunciation due to the vertical guidance not being within
tolerances. This does not constitute a downgrade, and the
approach can still be flown to LP minimums.

Figure 9-1 Map Page Description
The following information describes the ownship symbol
behavior in a helicopter that does not have a source of magnetic
heading information connected to the GTN. When greater than
15 knots groundspeed the map is oriented either north up with
ownship oriented to its current track or track up. When less than

15 kts groundspeed, the directional ownship icon is replaced
with a non-directional icon because it can't be determined if
the rotorcraft is going sideways or backwards. The map will
continue to orient to the current track if the map is selected
for Track Up. If the map is oriented to track up, then below
5 kts groundspeed the map orientation will "latch" to the last
valid track prior to the groudspeed going below 5 kts. The map
will reorient when the groundspeed again exceeds 5 kts. The
position of the ownship icon over the map is always the current
GPS position of the aircraft.

Traffic Applications - SURF, AIRB, etc.
The GTN ADS-B traffic display is capable of running in two “modes:”
Airborne Situational Awareness (AIRB) and Surface Situation Awareness (SURF).
AIRB is in operation in the en route environment, outside of five NM from
and 1,500 feet above the nearest airport.
SURF is in operation within the terminal environment (within five NM and
less than 1,500 feet above field elevation). When SURF is running, and the
zoom scale on the traffic display is less than two NM, the airport environment
(including taxiways and runways) is displayed in addition to traffic. This is to
aid in situational awareness of runway occupancy/availability, etc.
Due to the varying precision of the data received via ADS-B, ADS-R, and
TIS-B, all traffic targets may not be depicted on the traffic display. Because higher
data precision is required for display in the SURF environment, some targets
eligible for AIRB will not be displayed while SURF is active. Individual eligibility
for AIRB and SURF is depicted in the selected traffic data on the traffic page.

CDI Scale Selection
The CDI source and ILS CDI Capture type may be selected manually or
automatically. The selected CDI Scale will be reflected in the annunciation bar at
the bottom of the display.
CDI Scale Selection allows you to define the scale for the course deviation
indicator (both on the GTN unit's on-screen CDI and the external CDI). The
scale values represent full scale deflection for the CDI to either side. The default
setting is “Auto”. At this setting, the CDI scale is set to 2.0 NM during the
“en route” phase of flight. Within 31 NM (terminal area) of your destination
airport, the CDI scale linearly ramps down to 1.0 NM over a distance of 1 NM.
Likewise, when leaving your departure airport the CDI scale is set to 1.0 NM
and gradually ramps up to 2 NM beyond 30 NM (from the departure airport).
During GPS approach operations the CDI scale gradually transitions down to an
angular CDI scale. At 2.0 NM before the final approach fix (FAF), CDI scaling is
tightened from 1.0 NM to the angular full scale deflection (typically the angular
full-scale deflection is 2.0°, but will be as defined for the approach).
If a lower CDI scale setting is selected (i.e., 1.0 or 0.3 NM), the higher scale
settings are not selected during ANY phase of flight. For example, if 1.0 NM is
selected, the GTN unit uses this for en route and terminal phases and ramps down
further during an approach. Note that the Horizontal Alarm (HAL) protection

16.11.2 Pairing a Device
New devices can only be paired with the Flight Stream when it is in “Pairing
Mode”. The Flight Stream will be in pairing mode when the GTN is navigated
to the Connext Setup page and/or the Manage Paired Devices page. The pairing
must be initiated by the portable device. Pop-ups displayed on the portable
device and GTN will be displayed to confirm the pairing.

Connext Setup – GMA 35c
The GTN can interface with the GMA 35c Bluetooth audio panel. Using the
GMA 35c and the GTN, audio or telephone calls from a portable device can be
streamed over Bluetooth to the GMA. The GTN can also configure the Bluetooth
functions of the GMA 35c.

From the Connext Setup page, the pilot can enable/disable Bluetooth, change
the GMA 35c Bluetooth name, and manage paired devices. On the Paired
Devices page, the device status indicates if the portable device is connected and
communicating with the GMA 35c. Only one portable device can be connected
to the GMA 35c at a time. To connect a different device when one is already
connected, the existing connection must be ended by removing the portable
device pairing from the GMA 35c or by disconnecting or disabling Bluetooth on
the portable device. Removing a device from this page by pressing “Remove” will
require the device to be paired again before streaming audio.
NOTE: If the pairing is removed from either device (portable device or
GMA) it must be removed on the other device before a new pairing to that
same device is established again. Essentially, pairing must be removed on
both devices before repairing.
New devices can only be paired with the GMA 35c when it is in “Pairing
Mode”. The GMA will be in pairing mode when on the Connext Setup page or
the Manage Paired Devices page. The pairing must be initiated by the portable
device. A pop-up will be displayed on the portable device to confirm the pairing.
