Cruise in MAN Mode
In MAN m
ode, AT engagement activates the SPD XXXKT AT mode that controls
engine power within operational limits to reach and maintain the selected airspeed.
● NOTE ●
If the selected airspeed cannot be reached (e.g. selected airspeed is too high
with respect to maximum permitted engine power, or engine performance is
affected when inertial separator is ON, etc.), the AT maintains the maximum
permitted engine power and the resulting airspeed may remain below the
selected airspeed. This is to remain within the normal engine operating range.
●
Cruise in FMS mode
In FMS mode, the selectable cruise schedules are Recommended Cruise (
RCR ),
Maximum Cruise ( MXCR ), Long Range Cruise ( LRCR ), or Pilot-Defined Cruise.
In either mode, AT controls engine power within operational limits, in order to reach
and maintain the selected cruise schedule.
In FMS speed mode, the AT takes speed constraints of the flight plan into account. If
the active leg of the flight plan has a speed constraint, the speed constraint is
displayed above the airspeed indicator and the AT mode switches to SPD XXXKT .
Torque target display
In MAN or FMS mode, the optimum torque index is displayed on the torque gauge
when the inertial separator is OFF. Its display depends on the selected cruise
schedule - refer to GARMIN Pilot's Guide, Vertical Navigation section.
If either Recommended Cruise schedule or Maximum Cruise schedule is selected,
the Optimum Cruise Range is displayed. The lower and upper ends of the Optimum
Cruise Range arc respectively correspond to the Recommended Cruise and
Maximum Cruise power - refer to chapter 5.8 Engine operation.
If Long Range Cruise schedule is selected, the white ”T” is displayed, which
corresponds to the AT managed torque target in Long Range Cruise (50 %).
If Pilot-Defined Cruise schedule is selected, no torque index is displayed on the torque
gauge.
