Flight Control Panel

1. HDG/TRK Changeover Button

Pushing permits alternate selection of either heading (HDG) or track (TRK) to be displayed in the HDG/TRK display window and on the ND. Operation of this button before HDG/TRK HOLD does not affect the window target number. Operation of the button in the HDG/TRK mode compensates the window target to account for any difference in the magnetic heading and track angle but does not change existing control mode or AP/FD reference until the HDG/TRK selector is pushed or pulled.

2. HDG/TRK Display Window

Shows selected HDG or TRK. Window is blank when the AFS is controlling to the FMS flight plan. At initial powerup the window shows 000 as a preselected value if a valid magnetic heading is not available. If a valid magnetic heading is available at powerup, this is displayed. For powerup while airborne, the current heading is shown as the preselected value.

3. HDG/TRK and Bank Angle Limit Selectors

HDG/TRK Selector (Inner Knob) Turn to preselect:

• Rapid rotation causes large changes.
• Resolution for slow knob rotation is one degree per detent.

Pull to select:

• Disengages the NAV mode (if engaged).
• Selects the preselected heading/track and cancels the previous lateral mode. The aircraft follows and captures any selected HDG/TRK while in this mode.
• The display window displays the selected HDG/TRK.
• Once the target HDG/TRK is captured, the system will automatically transition to HDG/TRK HOLD mode and the selector must be rotated, then pulled to select a new heading. During the capture phase, the selected heading/track is changed when the selector is rotated.

Push to hold:

• Disengages the NAV mode (if engaged).
• Causes the aircraft to maintain the present HDG/TRK or, if the aircraft was turning, the heading during the turn plus or minus a small predicted increment to ensure a smooth rollout with no overshoot.
• Cancels VOR, LOC, NAV, and LAND ARMED modes.
• The window displays the capture HDG/TRK.
• Turning the knob in this mode preselects a new HDG/TRK. This requires selection by pulling the knob.

Bank Angle Limit Selector (Outer Knob): Allows selection of maximum bank angle in 5-degree increments (5 to 25 degrees). In the AUTO position bank angle limits vary with speed (bank limits decrease as speed increases). This selector cannot override FMS-computed bank angle limits. Bank angle limits are displayed on the top of the PFD attitude sphere.

4. NAV Switch

Push to arm the FMS NAV capture mode or resume FMS lateral control if the capture criteria are satisfied. The NAV armed mode can be cancelled by pushing HDG/TRK hold, selecting APPR/LAND arm, capturing the ILS localizer, or by capturing FMS NAV. After NAV capture, commands are supplied from the FMS. NAV arming is available on the ground once engines are started. NAV guidance is active at 100 feet AGL in FD mode. AP NAV guidance is not available until 400 feet AGL.

5. IAS/MACH Display Window

The preselected or selected IAS or MACH number is displayed in this window. The range is from 100 to 499 KIAS and M 0.500 to M 0.900. The left end of the display shows IAS or MACH depending on which function is selected. The window shows dashes when the AFS is controlling to the FMS flight plan speed.

6. IAS/MACH Changeover Button

Pushing the button permits alternate selection of IAS or MACH to be displayed in the window.

7. IAS/MACH Select Knob

Turn to preselect:

• Rapid rotation causes large changes and slow rotation causes slow changes in IAS/MACH display window.
• Each detent is equal to 1 knot or 0.001 Mach.

If the IAS is displayed, pushing the IAS/MACH changeover button allows display and preselection of the desired cruise Mach. The preselected IAS is retained and displayed when the changeover button is pushed again. At the altitude where the selected IAS corresponds to the preselected Mach, the display and the selected speed reference will automatically change to the Mach mode. The inverse operation (IAS preselection) is available for descent. Changeover to the equivalent Mach or airspeed value occurs automatically at 26,000 feet if no Mach has been preselected.

Pull to select:

• Disengages the FMS speed mode (if engaged).
• The preselected target speed becomes the selected speed.
• The window displays the selected speed.
• The aircraft will follow and capture any selected speed value while in this mode with a pitch or thrust change as appropriate.
• Once the selected speed is captured, the system will automatically revert to the speed hold mode and the IAS/MACH select knob must be rotated, then pulled, to select a new speed. During the capture phase, the selected speed is changed if the knob is rotated.

Push to hold:

• Disengages FMS speed mode (if engaged).
• The aircraft will maintain the present speed plus or minus any small increment if required for a smooth capture.
• The window displays the capture speed.
• Turning the knob in this mode preselects a new speed. The knob must be pulled to select the preselected speed.

8. FMS SPD Switch

Pushing selects the armed FMS speed, typically an ECON speed, and cancels any selected or preselected speed or Mach number. The IAS/MACH display window shows IAS -- or MACH -- and the FMA speed target and speed control legend changes from white to magenta. Pushing the FMS SPD switch within 10 seconds after preselecting an FCP speed results in editing the FMS-computed speed. The window shows IAS -- (or MACH --) and the PFD FMA speed is the edited FMS speed reference in white (magenta if equal to ECON speed). The FMS SPD mode is disengaged by pushing or pulling the IAS/MACH select knob or by engaging go-around modes. On takeoff, pushing the PROF switch above 400 feet AGL engages PROF and FMS SPD.

9. FEET/METER Changeover Button

The altitude tape on the right side of the PFD is always in feet. Pushing this button allows the pilot to select feet or meters on the FCP, FMA, and lower right corner of the PFD. When meters are selected the values are preceded by an M. When feet are selected the values ar preceded by an FT.

10. Altitude Display Window

Displays the selected or preselected altitude for altitude alerting and AP/FD altitude control (except during G/S mode). Range is from 0 to 50,000 feet. Display at initial powerup is 10,000 feet. Window is blank if both air data computer references fail.

11. Altitude Select Knob

Precision altitude selection increments (one detent) for slow knob rotation are:

• 500 feet above 10,000 feet.
• 100 feet below 10,000 feet.
• If BARO is selected on the ECP, a one-foot precision selection capability permits FCP selection of MDA value.
• 50 meters if METER is selected.

Turn to preselect:

• Sets the altitude reference.
• Window displays the preselected altitude reference.
• Sets FMS clearance ceiling (climb) or floor (descent) when PROF is engaged.

Pull to select:

• Disengages PROF (if engaged) and engages flight level change.
• Disengages vertical speed/FPA or altitude hold modes.
• Flight level change mode sets the ATS to climb thrust or descent idle clamp and AP/FD pitch control to speed. The aircraft climbs or descends directly to selected altitude.
• The aircraft will capture and hold any new altitude selected while in this mode.
• The FCP altitude target becomes the displayed reference on the FMA.

Push to hold:

• Engages altitude capture/hold.
• Disengages PROF (if engaged).
• Disengages VERT SPEED/FPA mode (if engaged).
• Altitude target becomes the current altitude plus or minus a small value required to give a smooth transition to level flight. This target value is displayed in the FCP window, FMA, and on the PFD.

12. PROF Switch

Push to engage the FMS vertical profile guidance if not previously engaged. After PROF engage, commands are supplied from the FMS (based on inserted flight plan). On takeoff, PROF will not engage until 400 feet AGL. On landing PROF can stay engaged until 50 feet. In takeoff mode, this switch will also engage FMS speeds.

13. V/S-FPA Changeover Button

Pushing permits alternate display and control of either vertical speed in fpm or FPA in tenths of degrees. When the V/S-FPA is not engaged, alternate function is not selected until the pitch thumbwheel is rotated. After V/S or FPA is engaged, the displayed value is always the selected value.

14. V/S-FPA Display Window

Displays vertical speed or FPA. Display is blank if V/S or FPA are not engaged. When FPA is selected, the value is in degrees and tenths. When V/S is selected, the value is in fpm.

15. Pitch Wheel

Rapid rotation results in large changes in the display window. Slow rotation results in 100 fpm (or 0.1 degree) changes per detent. A vertical speed bug is positioned on the PFD vertical speed tape corresponding to the selected vertical speed.

Roll to select:

• Disengages PROF, speed on pitch, altitude hold, and glideslope modes if LAND is not annunciated.
• Display window and target initializes to plus or minus 100 fpm (or 0.10 degree FPA) if engaged in altitude hold. Otherwise, initialization is to current vertical speed/FPA. Subsequent wheel changes result in changes in vertical speed/FPA selection.
• Pushing PROF resumes FMS profile operation at the selected vertical speed as an FMS edit. When the pitch wheel is moved, the AP will cancel the altitude capture mode (if engaged) and will not re-engage in altitude capture until the pitch wheel has come to rest for 2 seconds. The selected altitude will not be captured if the pitch wheel is repeatedly adjusted. In this case, the AP will toggle between vertical speed mode and altitude capture.

16. APPR/LAND Switch

Push to arm the APPR and LAND modes. LAND ARMED appears in the FMA roll control window. A tuned ILS is required to arm APPR/LAND.

17. AUTO FLIGHT Switch

Push to engage both ATs and one AP in the FD mode that has been selected. If no FD mode has been selected, the AP engages in HDG/TRK HOLD and either altitude hold (if aircraft about level) or vertical speed hold (if aircraft climbing/descending). After AP engagement, each push alternates the AP between AP1 and AP2. AP mode is always retained. AP1 or AP2 will appear on the FMA (top of PFD). On ground, pushing engages autothrottles only. Below 100 feet the AP will not engage. If the AP is engaged above 100 feet, it will remain engaged after passing below 100 feet only in LAND or GA modes. Operating hydraulic systems required for AP and auto pitch trim are as follows:

• AP1 requires HYD system 2 for flight controls and HYD system 3 for auto pitch trim.
• AP2 requires HYD system 1 for flight controls and auto pitch trim.

18. AFS OVRD OFF Switches (2)

Push down for emergency disconnect of respective autopilot and autothrottle. In OFF, an amber and gray bar comes into view. Additional FCC functions are affected as follows: Functions stay on: Altitude alerting, auto ground spoilers, auto pitch trim - LSAS, auto slat extend, elevator load feel, engine trim, flap limiting, FD, LSAS, speed protection - LSAS, stall warning, yaw damp/turn coordination, and windshear guidance. Functions go off: AP auto pitch trim, Roll control wheel steering, and speed protection - AP & ATS.

Gear Handle panel

1. Gear Handle

Mechanically positions landing gear hydraulic control valve for retraction or extension of landing gear. To move handle from UP or DOWN it must be pulled aft. An interlock prevents moving GEAR handle to UP if hydraulic pressure to landing gear trim system fails. A force of 160 pounds may be applied to GEAR handle without causing damage to system. Failure of the landing gear trim system prevents moving the GEAR handle to UP.

2. Gear Lights

Green illuminates when:

• GEAR handle is down and landing gear is down and locked.
• GEAR handle is up and landing gear is down and locked via the alternate gear extension lever.

Red illuminates when:

• Landing gear is not down and locked and GEAR handle is down.
• Landing gear is in transit or not in agreement with GEAR handle.
• Any unsafe gear condition exists.

All lights are extinguished when the GEAR handle is up and the landing gear is up and locked. Red and green illuminate when the respective main gear door maintenance safety hook is installed. An unsafe condition on one of the two gear indicating systems does not require a mandatory visual inspection. Any green indication indicates a safe gear.

3. CTR GEAR NORM/UP (switch)

Permits main gear to be extended without extending center gear. UP prevents center gear from extending when main gear is extended. Center gear warning circuits are inhibited. If switch is not illuminated, center gear will extend and retract when main gear extends and retracts by means of gear handle. If switch is illuminated, the center gear remains retracted regardless of GEAR handle position.

4. Handle Rel (button)

Releases anti-retraction mechanism and permits gear handle to be placed in UP in event of ground sensing release mechanism malfunction.
