250+ TOP MCQs on Air Traffic Control and Answers

Avionics Multiple Choice Questions on “Air Traffic Control”.

1. What are the two principal processes of air traffic management?
a) Air traffic control and traffic flow management
b) Air traffic control and Aircraft system maintenance
c) Traffic flow management and Aircraft system maintenance
d) Aircraft system maintenance and Radio communication
Answer: a
Clarification: The purpose of air traffic management is safe, efficient, and expeditious movement of the aircraft in the airspace. Its two major principles are air traffic control and traffic flow management.

2. Who provides assurance between the collision of aircraft with another aircraft or terrain?
a) ATM
b) Pilot
c) FMS
d) Autopilot
Answer: a
Clarification: The primary service provided by ATM is separation assurance for the prevention of collisions between aircraft and to prevent aircraft collisions with terrain and obstructions.

3. ATM also aids in search and rescue.
a) True
b) False
Answer: a
Clarification: A principle service of ATM is search and rescue, that is, notification of the appropriate organizations regarding aircraft in need of search and rescue assistance and support of these organizations during the ensuing operations.

4. Which of the following ensures standardization of ATM services worldwide?
a) FAA
b) ICAO
c) IAO
d) DGCA
Answer: b
Clarification: Standardization of the air traffic management practices internationally is the responsibility of the International Civil Aviation Organization or IACO, which is affiliated with the United Nations and located in Montreal, Quebec, Canada.

5. Who are not required to contact the ATM for navigation?
a) VFR operator
b) Co-pilot
c) Pilot
d) IFR operator
Answer: a
Clarification: Visual Flight Rules operator are responsible for avoiding collisions with obstacles, terrain and other aircraft by visually observing these hazards and maintaining visual separations. VFR operators are not required to contact ATM authorities and are not subject to their directions.

6. The aircraft whose attitude reference is solely based on the natural horizon follow ______
a) VFR
b) IFR
c) Pilot
d) FAA commands
Answer: a
Clarification: VFR flights usually involve small aircraft operated for personal or business purposes. Navigation may be by visual reference to the ground and aircraft attitude control may be based solely on the natural horizon visible through the windscreen of the aircraft.

7. Who is responsible for the separation of an aircraft from other aircraft in a controlled airspace?
a) ATM operator
b) Pilot
c) Co-pilot
d) Navigator
Answer: a
Clarification: In controlled airspace, the crew must operate in accordance with instructions received from ATM authorities, and these authorities are responsible for separating the aircraft from all other IFR aircraft.

8. What is the minimum visibility when flying below 10,000ft and following VFR?
a) One nautical mile
b) One kilometer
c) One statute mile
d) One mile
Answer: c
Clarification: VFR operators below 10,000ft MSL must have a minimum visibility of one statute mile. VFR operators are not required to contact ATM in the controlled or uncontrolled airspace.

9. What altitude does FL540 correspond to?
a) 54,000ft
b) 5.4 ft
c) 54 ft
d) 5400 ft
Answer: a
Clarification: Pressure altitudes are expressed as flight levels on hundreds of feet using three digits. Hence, FL540 represents a pressure altitude of 54,000 ft.

10. The lateral displacement error of the aircraft form the intended track given the course deviation signal is called as?
a) Navigation error
b) Pilot error
c) Flight technical error
d) Instrumental error
Answer: c
Clarification: Flight technical error is the lateral displacement error of the aircraft from the intended track given the course deviation error signal generated by the navigation system.
