Consider increasing Vr to performance limited weight Vr, maximum of 20 knot increase
If encountered carry out escape maneuver. Do not exceed PLI. Avoid using Stab Trim - Landing
Use most suitable, into wind runway
Land with shallow flaps
Stabilize approach as early as possible

- EXPLAIN THE OUTLINES ABOUT BRAKE SYSTEM? (AOM 14.20.4)
- Each main gear has a multiple disc carbon brake.
- Brake system includes:
anti-skid protection (includes touchdown and hydroplaning protection using inertial groundspeed. Locked wheel protection is provided using a comparison with other wheel speeds)
autobrake system
electric brake system
parking brake o Powered by 4 electric brake power supply units - Each brake assembly has 4 EBA’s (Electric Brake Actuators). The EBA’s are controlled by 4 EBAC’s (Electronic Brake Actuator Controller).
- Each EBAC controls a fore-aft wheel pair.

- Airplane on the ground
- groundspeed above 85 knots
- both thrust levers retarded to idle
- WHAT IS THE TAP? THE TAMS?
- TAP - Thrust Asymmetry Protection (AOM 7.20.9)
Automatic feature that provides protection against asymmetric thrust during takeoff or go-around by limiting thrust on the higher thrust engine.
Enhances safety by:
allowing a decrease in approach speed at lighter weights
providing engine-out control capability for speeds above stick shaker
allowing full rated thrust to be available for all-engine operation at all weights and airspeeds
Reduces thrust on the operating engine to ensure there is sufficient rudder for directional control when airspeed decreases below approximately V2 on a takeoff or below Vref on a go-around.
Only available when the flight controls are operating in normal mode and the EEC is in normal or alternate modes. - TAMS - Thrust Asymmetry Minimum Speed (AOM 15.20.14)
Displayed on the speed tape to provide pilots with situational awareness of the minimum control speed for operation with a large thrust asymmetry.
TAMS varies with weight and CG but will always be at least 10 knots above the minimum control speed during takeoff or goaround.
When airspeed decreases to TAMS, the AIRSPEED, AIRSPEED aural sounds and the Master WARNING light illuminates.
- DOES CLIMB PERFORMANCE GO DOWN BY TAP OPERATING? (AOM 7.20.9)
No. For airspeed where TAP does limit thrust, climb gradient is higher with TAP limiting thrust than it would be it TAP did not limit thrust. This occurs because additional thrust asymmetry creates more airplane drag than the thrust that was added.
- TURBULENCE PENETRATION SPEED? (AOM SP.16.20, AOR AW.10.1)
- 290 Knots below FL250.
2. 310 knots or Mach .84 at or above FL250.
- IF YOU WANT TO REDUCE AIRSPEED DUE TO TURBULENCE, HOW MUCH COULD WE REDUCE AIRSPEED? (AOM SP.16.20)
- Normally reduce to turbulence penetration speed only. Provides best margin between high and low speed buffet.
- Minimum if the airspeed is below Mach .84, fly at minimum maneuvering speed +15 knots or greater at any altitude.
- WHEN THE FMC IS INOPERATIVE, WHAT SPEED SHOULD BE USED? (AOM PP.30.6)
- Climb: 250/310/.84
- Cruise: 310/.84
- Descent: .83/290/250
- IS THE USAGE OF COST INDEX ONLY 80? (AOR PR.14-1.1, AOM pp.20.12)
NO
80 - Domestic
40 - International
20 - Cargo
- IN CASE OF COST INDEX 40 SET, DO YOU CHANGE ANY SPEEDS? (AOR PR.14-1.6)
- If descent speed calculated by FMS based on changed CI at cruise is slower than .83/290/250, change to intended speed no later than 10Nm before TOD.
- If Descent speed calculated by FMS based on changed CI at cruise is faster than .83/290/250, change to intended speed no later than 50Nm before TOD
- CAN YOU CHANGE THE FLIGHT CONTROL SYSTEM TO THE SECONDARY MODE BY YOURSELF?
NO
- COMPONENTS OF THE FLIGHT CONTROL SYSTEM? (AOM 9.20.1)
- alternate flap switches
- alternate pitch trim switches
- Control wheel pitch trim switches
- Rudder trim selector
- stabilizer cutout switches
- flap lever
- Speedbrake lever
- two control columns two control wheels
- to pairs of rudder pedals
- THE WAY OF SIGNAL FROM THE CONTROL COLUMN TO FLIGHT CONTROL SURFACES? (AOM 9.20.6, 9.20.9, 9.20.10)
- In the NORMAL mode, four ACE’s receive pilot control inputs and send these signals to three PFC’s (Primary Flight Computers) which verify the signals and information from other airplane systems to compute enhanced control surface commands, these commands are then sent back to the ACE’s then to the flight control surface actuators.
- In SECONDARY mode, the ACE’s continue to receive simplified computations from the PFC to generate flight control surface commands. Autopilot not available (and other functions).
- In DIRECT mode (failure of all three PFC’s). Inputs received by the ACE’s are sent directly to the control surface actuators.
- EXPLAIN THE CHARACTERISTICS OF THE FLIGHT CONTROL? (AOM 9.20.1)
- The primary flight control system uses conventional control wheel, column and pedal inputs from the pilot to electronically command the flight control surfaces. Provides conventional control feel and pitch responses to speed and trim changes. The electronic components provide enhanced handling qualities and reduce pilot workload.
- Highly redundant, with three operating modes: normal, secondary and direct.
- WHAT EICAS MESSAGE CAN SHOW IN THE SECONDARY MODE OR THE DIRECT MODE? (AOM 9.20.9, 9.20.10)
- FLIGHT CONTROL MODE (secondary)
2. PRI FLIGHT COMPUTERS (direct)
- WHEN DO YOU USE THE PFC DISCONNECT SWITCH?
When directed by the non-normal checklist
- WHAT SOURCE MOVES THE FLIGHT CONTROL SURFACES? (AOM 9.20.2)
- Hydraulic system normally
- Stabilizer electrically
- When all hydraulics lost, 2 spoiler pairs (4, 5 – 10, 11) are electrically operated and electrically actuated stabilizer using primary pitch trim switches.
- If there is a complete loss of signalling, direct wiring from the flight deck to the stabilizer and a spoiler pair allow control of pitch using alternate pitch trim switches and roll using the control wheel.
