Explanation: The electronic signals are transmitted using wires, in a FBW system. In order to transmit these flight controls, they need to be first converted into electronic signals.

Explanation: True, the conventional flight control systems require pilot’s involvement. However, modern fly by wire systems do not require the pilot’s involvement, and hence reduce workload.

Explanation: The Airbus A380 is the world’s largest airliner. The first A380 prototype was unveiled in Toulouse, France on 18 January 2005, with its first flight on 27 April 2005.

Explanation: The Antonov An-225 Mriya is the largest aircraft by weight. It is also the largest regular fixed-wing aircraft ever built. The aircraft is equipped with six engines.

Explanation: The NASA X-43A Pegasus aircraft holds the record for the fastest recorded powered aircraft flight. The aircraft broke its own world record of Mach 6.3 set in March 2004.

Explanation: Engine fuel is usually stored in the wings but some aircraft have additional fuel tanks in the fuselage. Generally, larger aircrafts, like the A380 have these additional fuel tanks.

Explanation: Yaw is a rotation about the vertical axis. It gives a side-to-side movement of the nose known as sideslip. The yaw axis is one of the three principle axes of an aircraft.

Explanation: True, the pitch of an aircraft is based on its angle of attack. It gives an up down movement of the aircraft nose measured by the angle of attack.

Explanation: Fly by wire systems offer low maintenance costs as compared to conventional controls and also improve efficiency by being lighter in weight.

Explanation: A rotary wing is typically unstable in yaw. Such wings usually require a vertical stabilizer in order to balance the unstable yaw. In case the yaw is unbalanced, the aircraft may go out of control and crash.

Explanation: The control systems are sometimes also used to increase or decrease drag. One such application is slowing the aircraft to a safe speed for landing.

Explanation: The tail section is also referred to as empennage. It is a structure that provides stability during flying phases. The section involves both horizontal and vertical control surfaces.

Explanation: True, avionics are generally electrical in nature. Avionic equipment’s have a vital role in making modern aircrafts more efficient and reliable. These equipment’s are costlier as compared to other older equipments.
