SYNCHRONIZATION
Synchronization enables you to synchronize the flight director bars with the current flight attitude.
The Sync switch on the yoke is
not simulated (because it is
hidden on the backside of the
yoke), so you must use the
standard key assignment “flight
director synchronization”. Please
note this standard key is NOT
assigned in FS/P3D so you must
assign a key to it before it can be used. We used [control]-[shift]-[s].
It has no effect in case the autopilot is engaged and only certain lateral and vertical modes allow
synchronization:
• Lateral
• Bank mode
• Vertical
• IAS mode
• MACH mode
• VS mode
Synchronization is annunciated by an amber SYNC indication on the
PFD. The message disappears after 3 seconds.
ALTITUDE ALERT SYSTEM
The pilots are notified on the PFD in case they are reaching /
leaving a preselected or selected altitude. The respective advisories
are all displayed on the PFD but in two different places:
• The readouts and bugs change colours and state according
the following rules:
• Approx. 1,000ft before reaching a preselected altitude an
aural warning for approx. 1 second is sounded, and the
readout and bugs flash in magenta for approx. 4 seconds
• Within 200ft of the (pre-)selected altitude the readout and
bugs come steady to indicate altitude capture
• In case the aircraft deviates for more than 200ft from the
selected altitude after capture, a 1 second tone will sound
and the readout and altitude bugs will start to flash amber
(and continue if the deviation occurs or the warning is
cancelled by pressing the ALT switch or selecting a
different altitude)
• In case the aircraft is 200ft below the selected altitude the flashing magenta bugs and readout will
cancel
• If the aircraft deviates further (± 1,000ft) from the selected altitude a 1 second tone sounds
• As soon as the aircraft is again within 200ft of the selected altitude the readout and bugs will cease to
flash
