Question 1: Under FAR Part 121, what is the minimum rest period required for flight crewmembers before a flight duty period?
- 6 hours
- 8 hours
- 10 hours (Correct answer)
- 12 hours
Correct answer: 10 hours
FAR Part 121 requires a minimum of 10 consecutive hours of rest before a flight duty period, allowing for at least 8 hours of sleep opportunity.
Question 2: An Airline Transport Pilot certificate is required to act as pilot-in-command of:
- Any aircraft over 12,500 lbs
- An aircraft in Part 121 air carrier operations (Correct answer)
- Any multi-engine aircraft
- Aircraft above FL180
Correct answer: An aircraft in Part 121 air carrier operations
An ATP certificate is required to serve as PIC in Part 121 scheduled air carrier operations, regardless of aircraft weight.
Question 3: What is the maximum altitude for Class B airspace in the US?
- 8,000 ft MSL
- 10,000 ft MSL (Correct answer)
- 12,500 ft MSL
- 14,500 ft MSL
Correct answer: 10,000 ft MSL
Class B airspace typically extends from the surface up to 10,000 feet MSL around the busiest US airports and requires an ATC clearance to enter.
Question 4: Under FAR 91.117, what is the maximum airspeed below 10,000 ft MSL?
- 200 knots IAS
- 250 knots IAS (Correct answer)
- 300 knots IAS
- No limit below 10,000 ft
Correct answer: 250 knots IAS
FAR 91.117 prohibits flight at more than 250 knots IAS below 10,000 feet MSL, except in Class B airspace surface areas where 200 knots applies.
Question 5: A Special VFR clearance in Class D airspace requires the pilot to have at minimum:
- An instrument rating
- A private pilot certificate (Correct answer)
- A commercial pilot certificate
- An ATP certificate
Correct answer: A private pilot certificate
Any certificated pilot may request a Special VFR clearance for flight in Class D airspace, though night SVFR requires an instrument rating and an IFR-equipped aircraft.
Question 6: ICAO designates airspace in classes A through G. Which class requires positive ATC control for all IFR and VFR flights?
- Class C
- Class A
- Class B (Correct answer)

ICAO Class B airspace (analogous to US Class B) requires ATC clearances and positive separation for all IFR and VFR flights operating within it.
