Right answer is (a) Lift dumper

Explanation: A spoiler may ALSO be called a lift duper, or lift spoiler. It is a device PLACED to INTENTIONALLY manipulate the lift component of an airfoil in a controlled WAY.

Correct ANSWER is (a) Inboard spoilers

Explanation: For DESCENT control in an aircraft, inboard spoilers are used. Further, when ROLL control is required, the aircraft MAKES use of outboard spoilers, which MAY also be referred to as mid span spoilers.

The correct option is (b) DECREASE descent rate

Explanation: Spoilers help in increasing descent rate without increasing speed. These devices CREATE a controlled stall over the PORTION of the WING behind it.

The CORRECT ANSWER is (a) On the top surface of a wing

Explanation: In an AIRCRAFT, the spoilers are placed on the top surface of a wing. They are plates that can be extended upward into the AIRFLOW to spoil it.

Correct choice is (d) Increased

For explanation I WOULD say: The airspeed is increased when an aircraft descends without spoilers. Further, the ENGINE will be at low POWER THUS producing less heat than normal.

Right choice is (c) Automatic

The BEST EXPLANATION: Automatic position is selected for lift dumpers on the landing approach. These DEVICES are deployed in a fraction of a SECOND at the moment of touchdown.

The correct OPTION is (b) SPOILERONS

For EXPLANATION: The combination of spoilers and ailerons is called spoilerons. These DEVICES ALSO avoid the problem of control reversal that affects ailerons.

The correct option is (a) False

The best I can explain: False, spoilers reduce the lift component of an AIRFOIL. This reduction is DONE in a CONTROLLED WAY by ALTERING the airflow over an aircraft wing.

The correct option is (c) Pilot INDUCED oscillation

To explain I WOULD SAY: PIO refers to pilot induced oscillation. These are oscillations that OCCUR due to the pilot’s effort to control the aircraft. Such oscillations are necessary for providing stability to the aircraft.

Right choice is (d) USING wires

To explain I would say: In an FBW system, the ELECTRONIC SIGNALS are transmitted using wires. The movements of flight controls are first CONVERTED to electronic signals and then transmitted.

Right answer is (b) ELECTRONIC

Explanation: The FBW system REPLACES the manual flight CONTROLS of an aircraft with an electronic interface. The manual flight controls may ALSO be referred to as conventional controls.

The CORRECT answer is (b) FALSE

The best EXPLANATION: False, fly by wire systems do not require pilot’s INVOLVEMENT. These systems protect the pilot operating outside of the aircraft’s safe PERFORMANCE envelope.

The correct answer is (d) PURELY

Easiest EXPLANATION: FBW SYSTEMS are purely electrically signaled systems. These are modern systems equipped on both military and commercial aircrafts. Such systems are ALSO helpful in reducing the gross weight of an aircraft.

Right choice is (d) BUILT in test equipment

The best explanation: BITE in aviation terminology refers to built in test equipment. Such equipment’s are used primarily on aircraft’s FEATURING FBW SYSTEMS in ORDER to conduct their preflight safety checks.

The correct option is (a) A320

For explanation I WOULD say: The Airbus A320 series of AIRCRAFTS were the FIRST Airbus airliners that used full-authority FBW CONTROLS. Boeing followed with its 777 aircraft.

Right choice is (d) APOLLO LUNAR Landing TRAINING Vehicle

Explanation: The Apollo Lunar Landing Training Vehicle was the first ever aircraft to FEATURE pure electronic FBW SYSTEMS. The aircraft first flew in 1968 and did not have any kind of mechanical or hydraulic backup.

The correct ANSWER is (C) Concorde

The EXPLANATION is: The Concorde was the first production fly-by-wire AIRLINER. The aircraft first flew on 2 March 1969 and retired on 24 OCTOBER 2003.

The correct answer is (a) ELECTRICAL

To elaborate: The AIRBUS A340 has a purely electrical back-up rudder CONTROL SYSTEM. However, beginning with the A380, all flight control systems on airbus aircrafts have back-up systems that are purely electrical.

The CORRECT answer is (C) Dassault Falcon 7X

For EXPLANATION I would say: The Dassault Falcon 7X was the first business jet with fly-by-wire CONTROLS. The aircraft OFFERS a range of 5,950 nautical miles.

The correct answer is (a) TRUE

The best explanation: True, Fly by optics is also referred to as fly by light. This is due to the USE of fiber optics. The system might be USED instead of fly by wire because it offers a HIGHER data transfer rate.

Correct choice is (c) Full AUTHORITY Digital Engine Control

Easiest explanation: FADEC refers to Full Authority Digital Engine Control. It is a system that permits OPERATION of the FLIGHT control SYSTEMS and auto throttles for the engines to be fully integrated.

Correct answer is (a) True

To explain: True, Boeing aircrafts such as the 777 ALLOW the pilots to COMPLETELY override the computerized flight control SYSTEM. However, Airbus flight envelope control SYSTEMS always retain ultimate flight control while flying under NORMAL law.

The correct answer is (c) SHIELDING

To explain: Shielding material is a material that attenuates CURRENT and electrical fields. DIFFERENT ESD materials POSSESS different characteristics and BEHAVE differently in the same environment.

Correct answer is (a) LOW charging

To elaborate: The anti-static materials are also known as low charging materials. These materials limit the buildup of charges by PREVENTION of triboelectric EFFECTS, through PHYSICAL SEPARATION.

The CORRECT OPTION is (a) Shielding

The best I can explain: Corona DISCHARGE is an alternate to photoemission. It is an electron emission effect used by antistatic systems. It is mostly used in a larger area, such as a factory floor or workshop.

The CORRECT choice is (d) Static BAR

For EXPLANATION I would say: An ionizing bar is sometimes referred to as a static bar. It is a type of an anti-static device used for removing static ELECTRICITY from a production line.

Right choice is (b) True

Explanation: True, HUMANS beings have natural electrical sources running through the body, thus touching an ESD unequipped can result in serious material damage or injuries.

The CORRECT answer is (C) Anti-static device

Easy EXPLANATION: Devices that decrease the magnitude of electrostatic DISCHARGE may be referred to as anti-static devices. Such devices if not used PROPERLY may also damage electrical components.

Correct answer is (a) Photoemission

The explanation: The process of neutralization of STATIC charges present in a SIGNIFICANTLY larger AREA, may be CALLED as photoemission. The process is based on the EMISSION of electrons into an area, which in turn neutralize the targeted object.

Correct CHOICE is (b) Pink

For EXPLANATION I would say: Dissipative bags are USUALLY pink in color. This is because of the dissipative chemical layer.These bags COME with a static dissipative coating or layer on the PLASTIC.

The CORRECT ANSWER is (a) False

Best explanation: False, in order to store components that are prone to damage caused ESD, manufacturers MAKE USE of antistatic bags. These bags prevent any damage to the components that may be caused DUE to ESD.

Right option is (c) Conductive antistatic BAGS

To elaborate: The conductive antistatic bags are manufactured with a layer of conductive metal. The conductive metal is often ALUMINUM ALONG with a dielectric layer of plastic covered in a static dissipative COATING.

Correct OPTION is (b) True
