Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
The initial track is modifiable on the SECTOR SEARCH page.
3R -- The ANGLE between successive pattern radials is entered and
D
displayed at 3R. Entry of sector angle values between 1 and
60 degrees is permitted.
Entry of a sector angle value resulting in an updated value is
calculated and displayed for radial space. Pilot--entered values are
displayed in large font and calculated values are displayed in small
font.
The sector angle is modifiable on the SECTOR SEARCH page.
4R -- The length of the search pattern RADIUS in NM is defined at
D
4R. The radius specifies the minimum distance away from the
starting position achieved by the search pattern waypoints. A turn
anticipation distance is added to the leg spacing distance so the
aircraft over--flies the outbound and inbound radials specified by the
pilot. When the radius is smaller than the radial spacing, an INVALID
ENTRY scratchpad message is displayed.
The pattern radius is modifiable on the SECTOR SEARCH page.
6R -- 6R is used to delete search patterns, activate newly defined
D
search patterns, or activate changes to the selected search pattern
definition parameters. During the initial definition of a new search
pattern, 6R is blank and not operational until all aspects of the
search pattern is defined. When all aspects of the search pattern is
defined with valid values, ACTIVATE is displayed and 6R becomes
operational.
When the SAR pattern is activated, the 6R prompt changes to
DELETE. Selecting the DELETE prompt removes the search
pattern from the active flight plan.
The ACTIVATE prompt is displayed at 6R when one of the search
pattern definition parameters is changed. Selecting the ACTIVATE
prompt activates the search pattern.
