DASSAULT AVIATION Proprietary Data
Heading / Track modes
Heading (HDG) or Track (TRK) mode is selected with the outer rotary switch (outer ring)
on the GP, then engaged by pressing the HDG / TRK pushbutton, which displays a green
ON symbol. Heading or Track value is set with the inner rotary knob (inner ring) and
displayed (in degrees) on the digital readout just above the knob, on the FMA and on the
HSI.
FIGURE 02-22-10-07 HEADING OR TRACK MODE
When engaged, the AP captures and hold the heading or track corresponding to the bug
position. Turn will be initiated in the direction the heading bug was turned to (even for
changes of more than 180° but less than 360°), at High or Low bank angle, as manually
selected on the AVIONICS window (AFCS Tab) or as automatically selected according to
current airplane altitude (High bank 28° below 30,000 ft (+/- 500 hysteresis), Low bank
14° above). Low bank symbol is displayed on the roll scale at the top of the ADI.
Pressing the PUSH SYNC rotary knob synchronizes selected heading or track value to
the current heading or track of the airplane.
NOTE
TRK mode is not available when pilot flying IRS parameters are not valid.
When activated, HDG or TRK mode can be disengaged automatically by AFCS logic (e.g. if
LOC mode is armed, there is an automatic transition from HDG / TRK mode to LOC mode) or
manually by pressing again on the HDG / TRK pushbutton (return to ROLL mode).
