Question 1
A newer flight control system, called?
A. Intelligent flight control system
B. Intelligently flight control system
C. Intelligent flight compensate system
D. Intelligent failures control system
View Answer
Ans : A
Explanation: A newer flight control system, called intelligent flight control system (IFCS), is an extension of modern digital fly-by-wire flight control systems.
Question 2
Which is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface?
A. FBA
B. FBS
C. FBD
D. FBW
View Answer
Ans : D
Explanation: Fly-by-wire (FBW) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface.
Question 3
Which of the following control yokes can be used to fly FBW aircraft?
A. Side-sticks
B. conventional flight
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: Side-sticks or conventional flight control yokes can be used to fly FBW aircraft.
Question 4
Servo-electrically operated control surfaces were first tested in the ?
A. 1925
B. 1930
C. 1935
D. 1940
View Answer
Ans : B
Explanation: Servo-electrically operated control surfaces were first tested in the 1930s on the Soviet Tupolev ANT-20.
Question 5
Why is the BFW system used?
A. Reduced chances of enemy detection
B. For communications in aircraft
C. Better navigation
D. To control aerodynamically efficient but unstable body
View Answer
Ans : D
Explanation: The literal meaning of Fly By wire system is flying by wires(I.e; electrically). One of the main advantages of using FBW is to exploit increased aerodynamic shapes at the cost of stability. The FBW system provides high integrity automatic stabilization to compensate for the loss of stability and provide overall better performance.
Question 6
How is fly by wire system implemented in an aircraft?
A. By using control rods and linkages connecting stick to control surfaces
B. By using high power radio transmitters and receivers
C. By using computers and actuators to control surfaces
D. Artificial intelligence
View Answer
Ans : C
Explanation: The fly by wire system uses actuators to move the control surfaces to maintain the stability of an aircraft. The signals sent by the pilot via the control stick is intercepted by the flight controller computer and signals are sent to the respective actuators to move the control surfaces.
Question 7
What type of system is classified as “Direct electric link system”?
A. Systems with parallel wire connection
B. System with serial wire connection
C. System with motion sensor feedback
D. System without motion sensor feedback
View Answer
Ans : D
Explanation: A FBW system by definition has to have a motion feedback system. Without these, the system is considered as “Direct electric system”. The information from these sensors is used to automatically stabilize the aircraft.
Question 8
What does FBW use to scale the control surface deflection according to the aircraft’s airspeed and height?
A. Flight Management System
B. Air Data Computer
C. Flight Control Computer
D. Autopilot system
View Answer
Ans : B
Explanation: FBW uses an Air Data System to scale the control surface deflection according to the aircraft’s airspeed and height variations. The need for air data information on the airspeed and height is to compensate for the very wide variation in the control surface effectiveness over the aircraft’s flight envelope of height and speed combinations. The Air Data Computer provides various information available from the airstream such as airspeed, altitude, and angle of attack.
Question 9
The General Dynamics F-16 was the first production aircraft to use digital fly-by-wire controls.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, The General Dynamics F-16 was the first production aircraft to use digital fly-by-wire controls.
Question 10

A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Fly-by-wire control systems allow aircraft computers to perform tasks without pilot input.
