7. Disconnect autopilot and press the
FD
key to remove the Flight Director command bars. An aural
tone will sound when the disconnect is accomplished.
8.4
Pitch Mode (PIT) & Altitude Alerting
1. With the Autopilot disconnected, establish straight and level flight at a minimum of 185 KIAS.
Pre-select an altitude 2000-ft above the aircraft current altitude. Once established, press the AP
key on the AFCS mode controller to engage the autopilot in the default pitch (PIT), roll (ROL)
modes, and altitude armed (ALTS) mode.
2. Center heading bug by pressing HDG knob. Engage HDG mode by pressing the
HDG
key on the
AFCS mode controller.
3. Using
the
NOSE UP/DN
wheel on the AFCS mode controller, set a climb attitude of at least 5
°
and adjust the power setting to maintain a safe climb speed. The autopilot should start a climb
toward the selected altitude.
4. At 1000 feet below the selected altitude, the selected altitude field will flash and change from
cyan text with a black background to black text with a cyan background. An aural tone will also
sound. At 200 feet below the selected altitude, the selected altitude will again flash and change
back to cyan text and a black background.
5. Prior to reaching the selected altitude the system will transition to ALT mode. At this point the
green “PIT” and the white “ALTS” will extinguish and be replaced by a green “ALT”. “ALT” will
flash for 10 seconds to indicate the transition to the new mode and the altitude reference will be
displayed in green to the right of “ALT”.
6. Verify the autopilot levels off within 50 feet of the selected altitude.
7. Repeat this procedure for a selected altitude at least 2,000 feet below the present altitude.
Maintain a descent rate of at least 500 feet per minute and airspeed of 185 KIAS or greater while
observing the selected altitude flashing, color reversal, and aural tone 1,000 feet above the
selected altitude. The selected altitude will again flash and reverse colors at 200 feet above the
selected altitude. The system will capture the desired altitude and transfer to the altitude hold
mode with minimal overshoot.
8. Disconnect the autopilot. Initiate a climb or descent away from the selected altitude. When the
aircraft altitude deviates 200 ft. from the selected altitude, the selected altitude will change to
amber text on a black background, flash for 5 seconds then remain steady, and a single aural
tone will sound. Return to straight and level flight.
8.5
Flight Level Change (FLC) Mode & Altitude Capture
1. Establish straight and level flight with the autopilot engaged in altitude hold (ALT) mode.
Synchronize the HDG bug to current aircraft heading and engage HDG mode. Select an altitude
at least 1,000 feet higher than present altitude using the ALT knob on the AFCS mode controller.
2. Engage
FLC
mode by pressing the
FLC
key on the AFCS mode controller. Green ‘FLC’, green
reference speed (aircraft’s airspeed when the FLC button was pressed), and “ALTS” will be
annunciated in white in the pitch window on PFD1 and PFD2.
