Auto brake System

1. AUTO BRAKE Selector

OFF

ABS is not armed but manual braking is available.

T.O.

Provides maximum braking from brake system 1 and 2 when spoilers deploy during RTO with ABS armed above 100 knots. Below 100 knots, MIN braking is provided.

MIN, MED, MAX

Selected braking level engages when spoilers are deployed automatically or manually during landing with ABS armed.

If any AFS land mode is selected with aircraft on ground, the ABS disarms and the ABS DISARM light illuminates.

2. ANTI-SKID OFF Switch

Push to select anti-skid off. Illuminates amber when anti-skid is selected off.

3. AUX HYD PUMP 1 Switch - blue

Turns on electric aux pump 1 to pressurize hydraulic system 3 if pressure is lost. Hydraulic system 3 powers brake system 2. Pump can also be turned on from the HYD control panel.

4. BRAKE SYS HYD PRESS Gage (1 and 2)

Pointer 1 shows hydraulic pressure in brake system 1. Pressure shown is highest of hydraulic system 1 or brake system 1 accumulator. Pointer 2 shows hydraulic pressure in brake system 2. Pressure shown is highest of hydraulic system 3 or brake system 2 accumulator.

SLAT STOW Switch - amber

SLAT STOW

With the FLAP/SLAT handle in retract position, pushing the SLAT STOW switch deactivates the slat extend function. Switch illuminates amber. With the FLAP/SLAT handle positioned greater than 3°, NO SLATS is displayed on the PFD.

The SLAT STOW alert is displayed on the SD CONFIGURATION page. A SLAT DISAG alert is displayed when operating the SLAT STOW switch with slats extended.

Pushing the SLAT STOW switch with slats stowed and flaps extended extends the slats.

Communication

1. Radio control panel

Pressing radio select button displays active and standby frequencies currently tuned for respective radio, and allows the pilot to change frequencies on that radio using the tuning knobs

2. Comm Sys Select buttons

Communication system select buttons are used to select the communication system from which transmissions will be made

3. Service Interphone Select button

4. Flight Interphone Select button

5. Volume control knobs

Volume controls for respective Communication system

Throttle Quadrant

1. PARK BRAKE Handle

Brakes are fully applied for parking by positioning the handle aft. Pressure from brake system 1 and 2 is maintained with trapped fluid.

2. PARK Light - amber

Illuminates amber when PARK BRAKE handle is set to park position. Will extinguish when parking brake is released.

3. LONG TRIM Handles

The handles provide direct mechanical control of the horizontal stabilizer control valves. The trim handles have the same function as the electric control wheel trim switches, except that they have override authority over LSAS or autopilot inputs except in DUAL or SINGLE LAND mode. Moving the handles together provides control of the horizontal stabilizer. Stabilizer movement rate is determined by airspeed and altitude. Both handles must be operated together to move the horizontal stabilizer.

4. SPOILER Handle

The spoiler handle is used to either select automatic operating modes or to control the manual modes of the spoiler system. When arming for automatic spoiler operation, the spoiler handle, which is spring-loaded to RET, must be at RET before it can be pulled up to armed. When armed (up), a red placard labeled ARM in white letters, is visible on both sides of the handle.

When auto spoilers are armed, automatic operation is as follows:

During a rejected takeoff, ground spoilers automatically extend when groundspeed is less than 80 knots, and any two of the three throttles move into reverse thrust. With groundspeed greater than 80 knots, moving any two throttles to idle deploys ground spoilers.
During landing, with flaps 30° or greater and after main wheel spinup, the spoiler handle moves to approximately the two-thirds position. At nose gear touchdown, the handle moves to full ground spoiler position and the ground spoilers fully extend.
After ground spoiler extension, advancing throttle 2 automatically moves the SPOILER handle to full forward, retracting the spoilers. If the number 2 engine throttle is not at idle at main gear spin-up it is possible that the AGS will initiate deployment and will then immediately retract the spoilers. If this occurs, ground spoilers must be manually extended.

Manual spoiler operation is as follows:

In flight, the handle controls the speed brake mode when the "T" handle release is squeezed and pulled aft to the 1/3, 2/3, or FULL position. The handle stops at FULL. 1/3
all 5 spoilers on both wings extend 10°.

2/3

all 5 spoilers on both wings extend 20°.

FULL

all 5 spoilers on both wings extend 30°.
On the ground, the handle controls the ground spoiler mode when pulled up and aft to the GROUND SPOILER position. Pulling the handle up again locks it aft.
The handle will not move to the GROUND SPOILER position until the nose gear strut is compressed during landing.

5. FLAP/SLAT Handle

Lifting FLAP/SLAT handle up and pulling aft to latch in preselected takeoff DIAL-A-FLAP detent, 28° go-around gate, or 35°/50° landing flap detent, extends the flaps and the slats. Rotating the FLAP T.O. SEL thumbwheel until the proper takeoff flap setting appears in the FLAP T.O. SEL indicator sets the takeoff DIAL-A-FLAP detent. The 28° go-around detent has a gate/stop to prevent inadvertent extension/retraction of the flaps. The handle can be maneuvered past the gate/stop. Lifting the handle up and aft past the go-around gate to either the 35° or the 50° landing detent extends landing flaps. Lifting the handle out of the detent and moving it forward past the go-around gate retracts landing flaps. Positioning the handle at the 0°/EXT detent (flaps retracted/slats extended) retracts the flaps without retracting the slats. Maneuvering the handle from the 0°/EXT detent gate to positively engage it in the FLAP UP/SLAT RET detent retracts the slats.

To prevent unintentional slat extension:

When retracting slats, be sure FLAP/SLAT handle is firmly engaged in the FLAP UP/SLAT RET detent. After flap/slat retraction, do not push, pull, or otherwise manipulate the FLAP/SLAT handle unless extension is desired.

6. DIAL-A-FLAP Detent Indicator

Indicates position of DIAL-A-FLAP detent. The detent position varies with the DIAL-A-FLAP setting.

7. FLAP T.O. SEL Indicator

Indicates the preselected DIAL-A-FLAP takeoff flap setting.

8. FLAP T.O. SEL Thumbwheel

When rotated, sets the DIAL-A-FLAP takeoff flap setting for any flap setting between 10° and 25°.

9. ENG START Switch (3) - amber

Pulling this switch will:

Energize a coil that holds the switch out.
Energize the engine starter valve open.
Illuminate the switch amber.
Supply power to the FADEC computer.

At about 45-52 percent the ENG START switch will pop in and the light will extinguish indicating that the starter air valve has closed. The MSC controls the start sequence. This switch cannot illuminate until the appropriate electrical bus is powered.

10. FUEL Switch (3) - red

This switch supplies electrical power to a fuel metering device. The fuel metering device then operates the fuel shutoff valve. This switch illuminates red during engine fire and ENG/APU FIRE test. Moving the switch to the ON initiates ignition and fuel if the ENG START switch is out and the ENG IGN switch is selected A or B. The FSC automatically turns on the fuel pumps in tanks 1, 2, or 3 when the respective ENG START switch or FUEL switch is moved to ON.
