SYS FIFTY FIVE X POH
When operating in the NAV / SOFT Mode and a needle deflection of 50%
or more is experienced for 1.5 minutes, the gain program will switch to
NAV/CAP/SOFT, increasing sensitivity and authority to reestablish the
aircraft on course.
When a course change of 10
!
or more is required at an enroute VOR,
select the new course using the course pointer (if HSI equipped or HDG
bug if DG equipped). The autopilot will acknowledge the changes and
automatically adjust for intercept.
4.2.2.1 Pilot Selectable Intercept Angles (DG or HSI)
The pilot may select an angle of intercept less than the standard 45
! .
Simply place the heading bug to the desired heading to be used for the
course intercept and push both HDG and NAV switches simultaneously.
Both HDG and NAV will be annunciated.
The selected heading will now be flown until the autopilot computes that
an on course turn must be made to minimize overshoot at the point of
intercept. At the time the on course turn begins, the HDG annunciator will
extinguish. If using a DG, it is imperative that the pilot set the HDG bug to
the selected course at this time.
NOTE:
Intercept angles greater than 45
!
usually result in some
course overshoot depending on the distance of the
aircraft from the station and aircraft speed. Therefore,
angles greater than 45
! are not recommended.
