3-12 Climb-out/Enroute
STRAIGHT AND LEVEL
NOTE
Straight and Level Definition
Pressing the “STRAIGHT AND LEVEL” button on
the autopilot will result in a zero bank, +2° pitch
angle attitude. It is not an altitude hold mode or a
zero vertical speed mode, nor does it hold a
heading.
NOTE
Straight and Level Usable Envelope
The Straight and Level button and functionality were
demonstrated to the POH limits of the aircraft (±60°
bank, ±30° pitch). Straight and Level is not to be
relied upon to stabilize an aircraft under all
conditions. Activating this mode will result in the
autopilot making its best effort to reach a wings
level, +2° pitch angle attitude. Depending on the
power setting and aircraft configuration, this could
produce a climb, steady altitude, or a descent
Straight and Level mode is entered by pressing the “STRAIGHT
& LEVEL” button on the autopilot control panel. The system will
light the control panel button in green (blinking) and immediately
change the bank and pitch as required to seek wings level, +2°
pitch angle conditions. Once straight and level is achieved, the
Straight & Level button on the control panel will be steady green
until another mode is selected. Upset recovery will be a smooth,
but depending on the entry attitude, aggressive maneuver
designed to achieve those steady state conditions in an expedited
manner. At sufficiently high power settings and aircraft
configurations (e.g. no flaps), a +2° pitch angle will result in a
shallow climb. At low power settings and/or aircraft
configurations, a +2° pitch angle may result in a descent.
