A330 Flight Controls Exam Questions
With Detailed Solution Scored A+
Fly-by-wire - ANSWER-Computers interpret pilot input and move the flight control
surfaces, as necessary, to follow their orders.
Pitch Control Surfaces - ANSWER-Achieved by 2 elevators and a Trimmable Horizontal
Stabilizer (THS)
Elevator Control - Electrical
Stabilizer Control - Electrical for normal/alternative control. Mechanical for manual
control.
Roll Control Suraces - ANSWER-Aileron Control - Electrical
Spoiler Control - Electrical
Spoilers - ANSWER-All used in flight as speed brakes
Used on ground as spoilers
Yaw Control - ANSWER-One rudder surface mounted on the vertical stabilizer
Rudder Control - Electrical
Yaw damping, turn coordination, & trim - Electrical
Mechanical linkages - ANSWER-THS mechanically linked to cockpit
, Flight Control Envelope Protections - ANSWER-Enhance flight safety by providing
protection against flight outside the normal flight envelope and protects against stall,
overstress, and overspeed.
Sidesticks - ANSWER-Spring-loaded to neutral and not mechanically coupled. Each
independently sends signals to the FCCs.
Simultaneous inputs by the CAPT and F/O are algebraically summed.
FCCs - ANSWER-Five computers process pilot and autopilot inputs. One computer of
any type is capable of controlling the aircraft and of assuring a safe flight and landing.
3 PRIM Computers
Flight Control Primary Computer (FCPC) - ANSWER-Normal, Alternate and Direct
control laws.
Speedbrake and ground spoiler control.
Protection speed computation.
Rudder travel limit.
2 SEC Computers
Flight Control Secondary Computer (FCSC) - ANSWER-Direct control laws including
yaw damper function.
Rudder trim and rudder travel limit.
2 Flight Control Data Concentrators (FCDCs) - ANSWER-Acquire data from 5 FCCs
and send data to the Electronic Instruments System (EIS) and Central Maintenance
Computer (CMC)
Normal Ops - ANSWER-one PRIM computer is the master. Processes orders and
sends them to the other computers, which then executes orders on their related servo-
control.
