BAvn Bachelor of Aviation Bachelor of Aviation Air Traffic Control 2 — Questions and Answers
Question 1: Which airspace class requires a clearance for IFR operations but allows VFR flight without a clearance?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Class C airspace requires ATC clearance for IFR but permits VFR flight with two-way radio contact and transponder.
Question 2: What is the primary tool used by en route controllers to maintain longitudinal separation between aircraft on the same route?
- Time-based separation
- Mach number technique (Correct answer)
- Speed control
- Altitude blocking
Correct answer: Mach number technique
The Mach number technique ensures aircraft at cruise maintain the same Mach speed so relative separation remains constant.
Question 3: A pilot reports an emergency but does not squawk 7700. What should the controller do?
- Wait for the pilot to squawk 7700 before acting
- Instruct the pilot to squawk 7700 and provide immediate assistance (Correct answer)
- Transfer the aircraft to the nearest approach control
- Declare the emergency on behalf of the crew
Correct answer: Instruct the pilot to squawk 7700 and provide immediate assistance
Controllers should instruct the aircraft to squawk 7700 and simultaneously provide assistance regardless of transponder status.
Question 4: What is the standard radar separation minimum for aircraft at or below FL180 in en route airspace?
- 3 nautical miles
- 5 nautical miles (Correct answer)
- 7 nautical miles
- 10 nautical miles
Correct answer: 5 nautical miles
FAA Order 7110.65 specifies 5 NM radar separation for en route aircraft at or below FL180.
Question 5: When must a controller issue a safety alert to a pilot?
- Only when the aircraft is in Class B airspace
- Whenever the controller observes a situation that could endanger the aircraft (Correct answer)
- Only if the pilot has not filed an IFR flight plan
- When traffic advisories have already been issued
Correct answer: Whenever the controller observes a situation that could endanger the aircraft
Controllers are required to issue a safety alert whenever they observe any condition posing an immediate threat to aircraft safety.
Question 6: Which phrase correctly indicates to a pilot that their transmission was received and understood?
- Copy
- Roger (Correct answer)
- Wilco
- Affirmative
Correct answer: Roger
"Roger" means the transmission was received and understood; "Wilco" adds the intent to comply.
Question 7: What is the purpose of a NOTAM (Notice to Air Missions)?
- To update pilot licenses
- To notify airmen of hazards or changes to aeronautical information (Correct answer)
- To assign transponder codes for IFR flights
- To coordinate between military and civilian ATC
Correct answer: To notify airmen of hazards or changes to aeronautical information
NOTAMs communicate time-critical aeronautical information such as temporary restrictions, outages, or hazards not yet in official publications.
