1Under 14 CFR Part 61, what medical certificate is required for a pilot exercising the privileges of an Airline Transport Pilot Certificate with a helicopter rating, and what is its validity period for a pilot who has reached their 40th birthday?
A.First-Class Medical Certificate, valid for 6 calendar months
B.First-Class Medical Certificate, valid for 12 calendar months
C.Second-Class Medical Certificate, valid for 12 calendar months
D.First-Class Medical Certificate, valid for 24 calendar months
Explanation: 14 CFR § 61.23(a)(1) requires a first-class medical certificate to exercise airline transport pilot privileges, and § 61.23(d) sets its duration. For operations requiring an ATP certificate, a pilot who has reached age 40 holds a first-class medical that expires at the end of the 6th month after the month of the examination; under age 40 it runs 12 calendar months.

A.1,200 total hours
B.1,500 total hours
C.1,000 total hours
D.500 total hours
Explanation: Under 14 CFR § 61.161(a), an applicant for an ATP certificate with a rotorcraft category and helicopter class rating must have at least 1,200 hours of total flight time as a pilot (unlike airplane ATP which requires 1,500 hours).
3According to 14 CFR § 61.161, of the 1,200 total flight hours required for a Helicopter ATP certificate, how many minimum flight hours must be accomplished specifically in helicopters?
A.200 hours
B.500 hours
C.100 hours
D.75 hours
Explanation: 14 CFR § 61.161(a)(4) mandates that an applicant for an ATP Helicopter rating must have at least 200 hours of flight time in helicopters, of which at least 75 hours must have been logged as pilot in command.
4Under 14 CFR § 61.57, what are the recent flight experience requirements for carrying passengers in a helicopter at night?
A.3 takeoffs and 3 landings to a complete stop at night within the preceding 90 days in a rotorcraft of the same category, class, and type (if type rating required)
B.3 takeoffs and 3 landings (touch-and-go permitted) at night within the preceding 60 days in any aircraft
C.6 instrument approaches and 3 night landings within the preceding 6 calendar months
D.3 takeoffs and 3 landings to a complete stop either day or night within the preceding 90 days
Explanation: 14 CFR § 61.57(b) specifies that to carry passengers between 1 hour after sunset and 1 hour before sunrise, a pilot must have made 3 takeoffs and 3 landings to a complete stop during that period within the preceding 90 days in an aircraft of the same category, class, and type.
5Under 14 CFR § 61.57(c), what is required for a helicopter ATP pilot to maintain instrument flight currency without taking an instrument proficiency check (IPC)?
A.Within the preceding 6 calendar months, log 6 instrument approaches, holding procedures and tasks, and intercepting and tracking courses through the use of navigational electronic systems in actual or simulated IFR
B.Within the preceding 12 calendar months, log 6 hours of instrument time and 3 instrument approaches in a helicopter
C.Within the preceding 90 days, log 3 hours of instrument time in a helicopter and 1 precision approach
D.Within the preceding 6 calendar months, log 3 hours of actual IFR time including 3 ILS approaches
Explanation: 14 CFR § 61.57(c) requires that within the 6 calendar months preceding the month of the flight, the pilot must perform and log at least 6 instrument approaches, holding procedures and tasks, and intercepting and tracking courses in actual or simulated IMC.
6An Airline Transport Pilot exercising privileges under 14 CFR Part 91 deviates from an ATC clearance during an emergency. According to 14 CFR § 91.123, when must the pilot submit a detailed report of that deviation to ATC?
A.Within 48 hours, only if requested by Air Traffic Control
B.Within 24 hours automatically following landing
C.Within 10 days to the nearest FAA Flight Standards District Office (FSDO)
D.Within 7 days to the National Transportation Safety Board (NTSB)
Explanation: Under 14 CFR § 91.123(d), each pilot in command who given priority by ATC in an emergency shall submit a detailed report of that emergency within 48 hours to the manager of that ATC facility, if requested by ATC.
7What is the minimum VFR fuel reserve required for a helicopter under 14 CFR § 91.151 during daytime operations?
A.20 minutes at normal cruising speed
B.30 minutes at normal cruising speed
C.45 minutes at normal cruising speed
D.15 minutes at economy power
Explanation: Under 14 CFR § 91.151(b), no person may begin a flight in a rotorcraft under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed, to fly after that for at least 20 minutes.
8Under 14 CFR § 91.167, what is the minimum fuel reserve required for a rotorcraft operating under IFR conditions?
A.30 minutes at normal cruising speed after reaching the destination or alternate airport
B.45 minutes at normal cruising speed after reaching the destination or alternate airport
C.20 minutes at holding power after reaching the destination or alternate airport
D.60 minutes at normal cruising speed under all IFR conditions
Explanation: Under 14 CFR § 91.167(a)(3), a rotorcraft operating under IFR must carry enough fuel to fly to the airport of intended landing, fly from that airport to the alternate airport (if required), and fly after that for 30 minutes at normal cruising speed.
9According to 14 CFR § 91.169, when is an alternate airport NOT required for a rotorcraft instrument flight plan under Part 91?
A.If at the ETA and for 1 hour after the ETA, the ceiling is forecast to be at least 1,000 ft above the airport elevation, or 400 ft above the lowest applicable approach minimums (whichever is higher), and visibility is at least 2 SM
B.If for at least 1 hour before and 1 hour after ETA, the ceiling is forecast to be at least 2,000 ft above airport elevation and visibility is at least 3 SM
C.If for at least 2 hours before and 2 hours after ETA, the ceiling is forecast to be at least 1,500 ft AGL and visibility is 5 SM
D.Rotorcraft operating under Part 91 IFR are always required to file an alternate airport regardless of weather forecasts
Explanation: 14 CFR § 91.169(b)(2)(ii) gives helicopters their own alternate exemption: at the estimated time of arrival and for 1 hour after the ETA, the ceiling must be at least 1,000 ft above the airport elevation, or at least 400 ft above the lowest applicable approach minima (whichever is higher), and the visibility at least 2 statute miles. Note the helicopter window starts at the ETA rather than 1 hour before it.
10What standard alternate airport weather minimums apply under Part 91 when filing a non-precision approach for a rotorcraft alternate where no specific alternate minimums are published?
A.Ceiling 200 ft above the minimum for the approach to be flown, and visibility at least 1 SM (but never less than the approach minimums)
B.Ceiling 800 ft and visibility 2 SM
C.Ceiling 600 ft and visibility 2 SM
D.Ceiling 400 ft above the minimum for the approach to be flown, and visibility 1/2 SM
Explanation: Under 14 CFR § 91.169(c)(2), for rotorcraft, standard alternate minimums at an airport with a published instrument approach are: Ceiling 200 ft above the minimum for the approach to be flown, and visibility 1 SM, but never less than the minimums specified for that approach.
