Init. 0-2, cyan box & #
Norm. 3-4, white box & cyan #
High. 5-9, white box & #
10-15 min. to reach high temp after brake application
Autobrakes (settings)
Landing 1, 2, 3, 4, MAX
ALL are decel rates. Max MANUAL is > Max AUTO
Takeoff - RTO
at > 85 kts. & both throttles to idle, then MAXIMUM braking applied (= to MAX MANUAL)
Anti skid protection
Touchdown, hydroplaning, and locked wheel protection is provided.
Autobrakes - Landing activation and disarm
After landing, autobrake application begins when:
Both thrust levers are retarded to idle, gear untilts, and the wheels have spun up.
AutoBrake - Disarm
Pedal braking applied.
Either thrust lever advanced after landing.
Speedbrake lever is moved from the full up position after the speed-brakes have deployed on the ground.
DISARM or OFF position selected on the AUTOBRAKES selector.
Autobrake fault.
Normal antiskid system fault.
Alternate brakes (hyd source & antiskid)
Transfer to LEFT HYD system automatically (shuttle valve) if right side hyd pressure is too low.
Antiskid is provided to laterally paired wheels so NO autobrakes.
Reserve Brakes
RIGHT HYD system from electic pump and reserve fluid. Switched on when manually selected.
Used when LEFT & RIGHT HYD systems are both lost.
Normal antiskid on all 8 wheels.
Brake accumulator (# of applications)
Pressurized from RIGHT HYD system.
At least ONE (possibly more) brake application.
Use ONE steady application, do NOT pump brakes.
Normal antiskid.
Brake accumulator isolation valve opens…
with total HYD system loss
Antiskid annunciator comes on…
with partial power loss to antiskid system AND system malfunction.
Rolls Royce engines (RB211)
Dual channel EEC

E.E.C. & E.L.C.
EEC - Electronic engine control
Provides EPR overboost protection.
ELC - Engine limiter control
Provides N1 overspeed protection.
Oil Pressure
2 sensors
- numerical value on EICAS
- < 18 psi gives low pressure annunciator
Main oil filter - NO BYPASS
Scavenge oil filter - YES bypass
Fuel control switches (Rich & Run)
Always motor engine during start until EGT < 100°C
If EGT = 0°C raise fuel control switch to RICH. When engine stabilized at idle, then raise sw. to RUN
If EGT > 0°C then raise to RUN
25% N3 - raise start lever during normal start
Deploying reversers (effect on A/T & speedbrakes)
Disengages A/T
Deploys speedbrakes
Need to come out of Reverse starting @ 60 kts, and be fully out by taxi speed
Rudder ratio fault
Rudder ratio changer on LEFT HYD Sys.
X-wind limit is 15 kts.
Avoid abrupt rudder input above 160 kts.
Spoilers
6 panels on each wing
Uses all HYD Sys. (diff Sys to diff panels)
Speedbrake moves 5 panels on each wing
AUTO extend ground spoilers
Spoilers ARMED
Throttles IDLE
HYD pressure to tilt sensor detects A/C on ground
Speedbrakes EXT (annunciator)

Slats & Flaps
LEFT HYD Sys
2 Inboard
8 Outboard
Flaps 1-20 = slats at midrange position
Flaps 25-30 = slats at landing position
Flap load relief
Retracts the flaps from 30 to 25 is airspeed > 162 kts. (or prevents extension to 30)
ALT FLAPS
0°-20° in about 2 min.
Slats are fully extended at flaps 20 (with alt Sys)
Stall Warning - Auto slats
Upon receiving a signal from the stall warning system, the slats automatically extend from the midrange position to the fully extended landing position. The slats retract a few seconds after the signal is removed.
