Sample Code of Federal Regulations questions

Try each one before opening the answer. Original questions written to the official exam objectives.

  1. Question 1

    Which of the following operations must comply with the flight, duty, and rest requirements of 14 CFR Part 117?

    • AA Part 121 all-cargo supplemental flight by a carrier that has not elected to use Part 117
    • BA Part 91 ferry leg directed by a Part 121 carrier when another segment is a passenger flight
    • CA Part 135 on-demand passenger charter flown in a turbojet airplane with two pilots
    • DA Part 91 subpart K fractional ownership flight carrying owners in a large turbojet
    Show answer and explanation

    Answer: B) A Part 91 ferry leg directed by a Part 121 carrier when another segment is a passenger flight

    Part 117 covers Part 121 passenger operations, plus Part 91 flights (other than subpart K) a carrier directs when any segment carries passengers. All-cargo operators may opt in under 117.1(d), but they don't have to.

    • AIncorrect. All-cargo Part 121 operators may choose to operate under Part 117 (117.1(d)), but they don't have to. Unless they opt in, they stay under the Part 121 subpart Q, R, or S limits.
    • BCorrect. 14 CFR 117.1(b) and (c) apply Part 117 to Part 91 operations (other than subpart K) directed by a Part 121 certificate holder if any segment is a domestic, flag, or supplemental passenger operation.
    • CIncorrect. Part 117 applies to Part 121 passenger operations. Part 135 operators follow the flight and duty limits in Part 135 subpart F.
    • DIncorrect. Section 117.1(b) and (c) specifically exclude Part 91 subpart K operations, which have their own flight and duty limits.

  2. Question 2

    Under 91.211, in an unpressurized airplane, required crew must use oxygen at all times above:

    • A10,000 ft MSL
    • B14,000 ft MSL
    • C12,500 ft MSL
    • D15,000 ft MSL
    Show answer and explanation

    Answer: B) 14,000 ft MSL

    • AIncorrect. It's above 14,000 ft.
    • BCorrect. Above 12,500 ft after 30 minutes.
    • CIncorrect. That's the 30-minute rule.
    • DIncorrect. That's for passengers.

  3. Question 3

    After an accident, the operator must file NTSB Form 6120.1 within:

    • A48 hours
    • B10 days
    • C30 days
    • D90 days
    Show answer and explanation

    Answer: B) 10 days

    • AIncorrect. It's 10 days.
    • BCorrect. 49 CFR 830.15.
    • CIncorrect. It's 10 days.
    • DIncorrect. It's 10 days.

  4. Question 4

    How much night flight time does an ATP airplane applicant need under 14 CFR 61.159?

    • A50 hours
    • B100 hours
    • C25 hours
    • D250 hours
    Show answer and explanation

    Answer: B) 100 hours

    • AIncorrect. The requirement is 100 hours.
    • BCorrect. Some night landings can substitute partially.
    • CIncorrect. The requirement is 100 hours.
    • DIncorrect. That's the PIC requirement.

  5. Question 5

    Under 14 CFR 91.9(a), no person may operate a civil aircraft without complying with the operating limitations specified in the approved Airplane or Rotorcraft Flight Manual, markings, and which other source?

    • APlacards
    • BManufacturer's service bulletins
    • CApplicable advisory circulars
    • DThe aircraft maintenance manual
    Show answer and explanation

    Answer: A) Placards

    14 CFR 91.9(a) requires operation within the limitations in the approved flight manual, markings, and placards, or as otherwise prescribed by the certificating authority of the country of registry.

    • ACorrect. 91.9(a) names the approved flight manual, markings, and placards (or limitations otherwise prescribed by the certificating authority of the country of registry).
    • BIncorrect. Service bulletins give maintenance or modification information. 91.9 does not list them as a source of operating limitations.
    • CIncorrect. Advisory circulars are guidance material. They do not set an aircraft's operating limitations under 91.9.
    • DIncorrect. The maintenance manual covers maintenance procedures. 91.9 points to the approved flight manual, markings, and placards.

  6. Question 6

    An unrestricted ATP airplane applicant generally needs total flight time of at least:

    • A1,500 hours
    • B250 hours
    • C1,000 hours
    • D3,000 hours
    Show answer and explanation

    Answer: A) 1,500 hours

    • ACorrect. 14 CFR 61.159(a).
    • BIncorrect. That's commercial.
    • CIncorrect. That's a restricted ATP path.
    • DIncorrect. It's 1,500 hours.

  7. Question 7

    Under 14 CFR 121.434, a pilot completing initial training as pilot in command of a Group II (turbojet) airplane must acquire what operating experience (IOE)?

    • A25 hours, including at least 4 operating cycles, under the supervision of a check pilot
    • B15 hours, including at least 4 operating cycles, under the supervision of a check pilot
    • C25 hours, including at least 4 operating cycles, under the supervision of any line captain
    • D20 hours, which may be cut by up to 50% by adding extra takeoffs and landings
    Show answer and explanation

    Answer: A) 25 hours, including at least 4 operating cycles, under the supervision of a check pilot

    Initial IOE for Group II airplanes is 25 hours, including at least 4 operating cycles, done under check pilot supervision. The 50% takeoff-and-landing substitution does not apply to Group II initial training.

    • ACorrect. Section 121.434(c) requires 25 hours for initial training in Group II airplanes, including at least 4 operating cycles (at least 2 as pilot flying), performed under the supervision of a check pilot.
    • BIncorrect. 15 hours is the initial-training figure for Group I reciprocating airplanes and the transition figure for Group II second in command, not Group II PIC initial training.
    • CIncorrect. The hours are right, but 121.434 requires supervision by a check pilot, not any line captain.
    • DIncorrect. 20 hours is the Group I turbopropeller initial figure. Under 121.434(f), the 50% reduction does not apply to Group II initial training.

  8. Question 8

    Operating in RVSM airspace requires specific authorization between:

    • AFL410 and FL600
    • BFL180 and FL290
    • CFL290 and FL410
    • D10,000 ft and FL180
    Show answer and explanation

    Answer: C) FL290 and FL410

    • AIncorrect. It's FL290 to FL410.
    • BIncorrect. It's FL290 to FL410.
    • CCorrect. With 1,000 ft vertical separation.
    • DIncorrect. It's FL290 to FL410.

  9. Question 9

    Under Part 117, what sleep opportunity must the required rest period include?

    • A4 hours
    • B8 uninterrupted hours
    • C6 hours
    • D12 hours, in two blocks
    Show answer and explanation

    Answer: B) 8 uninterrupted hours

    • AIncorrect. It must be 8 hours.
    • BCorrect. The rest period is at least 10 hours.
    • CIncorrect. It must be 8 hours.
    • DIncorrect. The sleep opportunity is 8 hours.

  10. Question 10

    Under 14 CFR Part 117, how is deadhead transportation that a certificate holder requires of a flightcrew member treated?

    • AIt can count toward the required 10-hour rest period if the crewmember rides in the cabin as a passenger
    • BIt is duty, and it is part of the flight duty period when it comes before a flight segment without an intervening rest
    • CIt is logged as flight time and counts toward the 100-hour and 1,000-hour flight time limits of 117.23
    • DIt is excluded from both duty and rest, because the crewmember is not operating the aircraft at the time
    Show answer and explanation

    Answer: B) It is duty, and it is part of the flight duty period when it comes before a flight segment without an intervening rest

    Under Part 117, required deadhead transportation is duty and never rest. It is part of the FDP when it comes before or between flight segments without a required intervening rest period.

    • AIncorrect. Under 117.3, a rest period requires freedom from all restraint by the certificate holder. Required deadhead transportation is listed as duty, so it can't count as rest.
    • BCorrect. Section 117.3 lists deadhead transportation in the definition of duty. The FDP definition includes deadhead that occurs before or between flight segments without a required intervening rest period.
    • CIncorrect. A deadheading crewmember rides as a passenger or non-operating crewmember. That time is duty, not flight time toward the flight time limits.
    • DIncorrect. Section 117.3 explicitly includes deadhead transportation in the definition of duty. Also, 117.25(g) requires extra rest when deadhead exceeds the applicable Table B FDP limit.
