Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
The default turn direction is right and the turn direction is modifiable
on the SECTOR SEARCH page.
3L -- The RADIAL SPACE (radial leg spacing) or distance between
D
successive cross--track search pattern legs in NM is defined at 3L.
The radial leg spacing is related to mean track spacing often used
to define the distance between successive radials. Mean track
spacing is one half of radial spacing. Entry of a radial space value
greater than the pattern radius is not permitted.
When the entered value for radial space is greater than the pattern
radius, an INVALID ENTRY scratchpad message is displayed.
Entry of a valid radial space value and an updated value is calculated
and displayed for sector angle.
Pilot entered values are displayed in large font and calculated values
are displayed in small font.
The radial spacing is modifiable on the SECTOR SEARCH page.
4L -- A default SPEED of 90 kts is displayed and the speed is
D
modifiable on the SECTOR SEARCH page.
6L -- Restores the default parameters and returns to the FMS
D
PATTERNS page or restart the search pattern at the start position
specified at 1L.
The CLEAR prompt is available during the initial definition of the
search pattern and is available when the search pattern is not yet
active. Selecting CLEAR results in the default parameters being
restored and transitions back to the FMS PATTERNS page.
The RESTART prompt is available after the search pattern becomes
active in the active flight plan. When returning to the SECTOR
SEARCH page, the RESTART prompt is displayed when a search
pattern is active. When RESTART is selected, the search pattern is
restarted with the displayed search pattern.
2R -- The INIT TRK (initial track) used in the search pattern is defined
D
at 2R. The default heading displayed is the inbound course into the
search pattern starting position waypoint when *SEARCH* is placed
on any flight plan waypoint other than the FROM waypoint.
CUR TRK is displayed when *SEARCH* is placed on the FROM
waypoint in the active flight plan, or the inbound course from the
present position when the start position is changed from the default
value.
