Flight Director Modes
The flight director is a display of the flight profile commanded from the autopilot. A remote
switch allows the control of the autopilot modes between off, autopilot, and autopilot with flight
director, and flight director only (“hand flying” the autopilot flight director commands). The
flight director command bars are limited to ± 30° in roll and ± 10° in pitch with respect to the
aircraft reference symbol.
Autopilot Operation During PFD Failures
In the unlikely event of a total PFD failure, the autopilot can still be controlled via its control
head. GPS roll steering (GPSS Mode) is the only autopilot horizontal mode available. Alt Hold
mode and VS mode are still available and may be controlled using the Alt and VS buttons and
the rotary knob on the autopilot control head. See the autopilot user’s guide for usage
instructions.
CAUTION
When engaging the altitude capture mode, confirm that both ALT and VS
are engaged on the autopilot. If VS is not engaged, the autopilot will level the
aircraft at the current altitude when ALT is engaged on the autopilot.
NOTE
Only GPS/NAV 1 is capable of being the navigation source to the autopilot in
the event of a PFD failure.
Wind Vector and Track Line
The wind vector on the HSI (see Figure 7 - 10) is very useful in any phase of flight where winds
aloft should be taken into account. A combination of the wind vector and projected track line can
be used to your advantage in navigation tasks. A very useful technique is to align the projected
track line with the desired course. This will take the guesswork out of determining proper crab
angles for wind corrections.
