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.

The Sector Search SAR pattern starts at the initial waypoint and follows the
initial track for the desired leg length. A 60° turn in the initial turn direction is
followed by another leg with the desired leg length, another 60° turn, and then
a leg back to the initiating waypoint. The next sector starts with a leg continuing
on the same course outbound from the initiating waypoint and is followed by
the same sequence of legs and turns. The third sector follows the same pattern.

The procedure turn portion of an approach is stored as one of the legs of

required for any other type of approach. Roll steering is provided to aircraft with
compatible autopilots.
NOTE: The steering provided for the procedure turn does not guarantee
that the aircraft will stay within charted procedure turn boundaries. As
such the crew will need to ensure that the approach is flown within the
confines of the charted procedure.

6.12.2
Flying the LP Approach
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.
6-18
Garmin GTN 625/635/650 Pilot’s Guide
190-01004-03 Rev. J
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.
6. As you cross the FAF, the destination sequences to the MAP.
With the needle on the external CDI (or HSI) centered, fly
toward the MAP, observing the altitude minimums dictated
by the approach plate.
7. 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).
8. As you approach the MAP, a waypoint message (“Arriving at
Waypoint”) appears on the bottom of the screen.
9. At the MAP initiate the missed approach, if necessary. Once
the GTN crosses the MAP, sequencing will be suspended.
Prepare the aircraft for missed approach operation. Touch
the Unsuspend key to sequence to the Missed Approach
procedure.
NOTE: For missed approaches with heading legs, fly manually until the
first active course leg is reached.
10. Fly the guidance provided by the GTN to the MAHP and hold.

NOTE: The electronic map is an aid to navigation and is designed to
facilitate the use of authorized government charts, not replace them.
Land and water data is provided only as a general reference. The accuracy
of the land and water data is not suitable for use as a primary source of
navigation and should only be used to supplement official government
charts and notices.
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.

Fuel Range Ring
Foreword
NOTE: This feature is available in software version 6.00 and later.
When interfaced with a fuel computer, the GTN can display a fuel range ring
which shows an estimate of the remaining flight distance at the current fuel
consumption rate and groundspeed. If either fuel quantity or fuel flow sensor
data is not received, the GTN will use the Fuel on Board or Fuel Flow values
on the Utilities – Fuel Planning page. If both fuel quantity and fuel flow are not
received by the GTN, the Fuel Range Ring will be removed. A dashed green
circle indicates the selected range to reserve fuel. A solid yellow circle indicates
the total endurance range.

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.
Map
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.

HTAWS Alerts
Alerts are issued when flight conditions meet parameters that are set within
HTAWS software algorithms. HTAWS alerts employ either a CAUTION or a
WARNING alert severity level. When an alert is issued, visual annunciations
are displayed. Aural alerts are simultaneously issued. Annunciations appear in a
dedicated field in the lower left corner of the display.
Annunciations are color-coded according to the HTAWS Alert Summary
table. Pop-up terrain alerts will occur if an HTAWS alert is activated while not

Echo Tops
Echo Tops data shows the location, elevation, and direction of the highest

clouds; rather it indicates the highest altitude at which precipitation is detected.
This information is determined from NEXRAD data.
