When Does Turn Anticipation Begin?
The system smooths adjacent leg transitions based on a normal 23° bank angle (with the ability to roll up to 27°) and provides three pilot cues for turn anticipation:
-
A waypoint alert (‘Next HDG ###° in # seconds’) appears on the PFDs 10 seconds before the turn point and flashes as it counts down to zero.
-
A flashing turn advisory (‘Turn [right/left] to ###° in # seconds’) appears on the PFD 10 seconds before the turn and flashes as it counts down to zero. ‘Turn [right/left] to ###° now’ or ‘Next [DTK/HDG] to ###° now’ is displayed when the pilot is to begin the turn and the HSI (GPS mode) automatically sequences to the next DTK or HDG value.
-
The To/From indicator on the HSI flips momentarily to indicate the midpoint of the turn has been crossed.
