What this exam covers
5 real sample questions
The supplied clearance sends the pilot to Taxiway Charlie, but the pilot expected Alpha and begins turning toward Alpha from habit. What is the correct response?
A. Stop safely, verify position and clearance, and request clarification rather than continuing on expectation
B. Continue because expected routes override clearances
C. Turn off the airport diagram
D. Ask a passenger which route looks shorter
Show answer and reasoning

Correct answer: A. Stop safely, verify position and clearance, and request clarification rather than continuing on expectation

Expectation bias can make a pilot see or hear the anticipated route. Stopping removes time pressure and allows a clearance, signage, marking, and diagram cross-check before an incursion occurs.

  • B: The issued clearance controls unless amended.
  • C: Removing a position reference worsens uncertainty.
  • D: Passenger route preference does not establish ATC authorization.

The supplied aircraft record shows a standard airworthiness certificate with no stated expiration date. When does that certificate remain effective?
A. While the aircraft remains U.S.-registered and maintained and operated in accordance with applicable requirements
B. For 12 calendar months after issue
C. Only until the next 100-hour inspection
D. Until aircraft registration is renewed, regardless of maintenance
Show answer and reasoning

Correct answer: A. While the aircraft remains U.S.-registered and maintained and operated in accordance with applicable requirements

A standard airworthiness certificate generally remains effective as long as the aircraft remains registered in the United States and is maintained and operated in accordance with applicable airworthiness requirements. It must also be displayed as required.

  • B: A standard airworthiness certificate does not expire annually merely with time.
  • C: A 100-hour inspection does not define the certificate's duration.
  • D: Registration alone is insufficient when the aircraft is not maintained or operated as required.
Source: 14 CFR 91.203(a)-(b)
A commercial pilot completed a flight review 25 calendar months ago and has had no later flight review or qualifying proficiency check. May the pilot act as PIC on a local personal flight today?
A. No; a flight review or qualifying exception must have been completed within the preceding 24 calendar months
B. Yes; a commercial certificate removes the flight-review requirement
C. Yes, if no passengers are carried
D. No, unless the pilot retakes the commercial knowledge test
Show answer and reasoning

Correct answer: A. No; a flight review or qualifying exception must have been completed within the preceding 24 calendar months

A commercial certificate does not waive 14 CFR 61.56(c). Unless an exception applies, a pilot may not act as PIC without a flight review completed since the beginning of the 24th calendar month before the month of flight.

  • B: Commercial privileges do not eliminate recurrent flight-review requirements.
  • C: The requirement applies to acting as PIC, not only to passenger carriage.
  • D: An expired flight-review interval is restored through a flight review or qualifying exception, not a new knowledge test.
Source: 14 CFR 61.56(c)-(d)
A commercial pilot advertises sightseeing flights to the public and supplies both pilot and airplane for compensation. Which statement is most accurate?
A. The operation is automatically legal because the pilot holds a commercial certificate
B. Commercial pilot privileges alone do not authorize an operation that requires an operating certificate under Part 119
C. The operation is private carriage whenever each passenger pays separately
D. Part 119 never applies to sightseeing flights
Show answer and reasoning

Correct answer: B. Commercial pilot privileges alone do not authorize an operation that requires an operating certificate under Part 119

A commercial pilot certificate authorizes pilot privileges, but it is not an air-carrier or commercial-operator certificate. Holding out transportation to the public while supplying pilot and aircraft may require authority under Part 119 unless a specific exception applies.

  • A: Pilot qualification and operational certification are separate legal questions.
  • C: Separate payment does not convert public holding out into private carriage.
  • D: Some nonstop sightseeing operations may fit a stated exception, but the category is not universally exempt and other requirements apply.
Source: 14 CFR 119.1(a), (e)
The supplied record shows a 35-year-old pilot received a second-class medical certificate on April 18, 2025. Through what date may that certificate support exercising commercial-pilot privileges, assuming no disqualifying condition?
A. April 18, 2026
B. March 31, 2026
C. April 30, 2026
D. April 30, 2027
Show answer and reasoning

Correct answer: C. April 30, 2026

For second-class operations, a second-class medical certificate is valid through the end of the 12th month after the month of examination. An April 2025 examination therefore supports second-class privileges through April 30, 2026.

  • A: Medical duration is measured by calendar month, not the anniversary day.
  • B: This ends the certificate one month too early.
  • D: The longer duration potentially applicable to lower-class privileges does not extend commercial second-class privileges.
