A.30 days
B.60 days
C.90 days
D.120 days
Explanation: 14 CFR § 135.247(a) requires that no certificate holder may use any person, nor may any person serve, as pilot in command of an aircraft carrying passengers unless within the preceding 90 days that person has made at least three takeoffs and three landings as sole manipulator of the flight controls in an aircraft of the same category, class, and type.

A.Every 6 calendar months
B.Every 12 calendar months
C.Every 24 calendar months
D.Every 36 calendar months
Explanation: 14 CFR § 135.299(a) stipulates that no certificate holder may use a pilot, nor may any person serve, as a pilot in command of an aircraft unless, since the beginning of the 12th calendar month before that service, that pilot has passed a flight check given by the Administrator or an authorized check pilot in one of the types of aircraft to be flown.
6Under 14 CFR 135.297, what is the validity period of an Instrument Proficiency Check required for a Pilot in Command operating under IFR?
A.6 calendar months
B.12 calendar months
C.18 calendar months
D.24 calendar months
Explanation: 14 CFR § 135.297(a) requires that no certificate holder may use a pilot, nor may any person serve, as pilot in command of an aircraft under IFR unless, since the beginning of the 6th calendar month before that service, that pilot has passed an instrument proficiency check given by an authorized check pilot or the Administrator.
7Under 14 CFR 135.223, when is an alternate airport required for an IFR flight in a single-engine airplane under Part 135?
A.Always required for all single-engine IFR passenger flights, regardless of weather forecasts
B.Required unless forecasts indicate ceiling at least 1,500 ft above lowest circling MDA (or 2,000 ft above airport elevation) and visibility at least 3 miles for 1 hour before to 1 hour after ETA
C.Required only when destination weather is below 1,000 foot ceiling and 2 miles visibility at ETA
D.Required only when destination weather is below published landing minimums at ETA
Explanation: 14 CFR § 135.223(b) specifies that no alternate is required if, for at least 1 hour before to 1 hour after ETA, weather reports/forecasts indicate the ceiling will be at least 1,500 feet above the lowest circling MDA (or 1,500 ft above lowest published minimum or 2,000 ft above airport elevation, whichever is lower), and visibility will be at least 3 miles (or 2 miles more than the lowest applicable visibility minimums). Otherwise, an alternate must be designated.
8According to 14 CFR 135.225, may a single-engine airplane operating under Part 135 take off under IFR when the weather at the departure airport is below published IFR landing minimums?
A.Yes, provided a takeoff alternate airport located within 1 hour flying time at normal cruise speed is designated
B.No, single-engine aircraft carrying passengers under Part 135 may not take off under IFR when weather is below published IFR landing minimums
C.Yes, if the pilot holds an ATP certificate and the departure visibility is at least 1/2 SM
D.Yes, provided the departure airport has a radar approach control facility active
Explanation: Under 14 CFR § 135.225(a) and OpSpecs, single-engine aircraft operating in Part 135 passenger operations cannot take off under IFR when weather conditions are below published IFR landing minimums because single-engine aircraft cannot meet single-engine takeoff alternate requirements if an engine fails upon takeoff.

A.Continuous oxygen is required for the pilot for any duration above 10,000 feet MSL
B.Oxygen is required for the pilot for that part of the flight at those altitudes that is of more than 30 minutes duration
C.Oxygen is only required if operating at night
D.No oxygen is required until reaching 12,500 feet MSL
Explanation: 14 CFR § 135.157(a)(1) requires that for unpressurized aircraft, each pilot must use supplemental oxygen for that part of the flight at cabin pressure altitudes above 10,000 feet up to and including 12,000 feet MSL that is of more than 30 minutes duration.
10According to 14 CFR 135.157, at what cabin pressure altitude must each required flight crewmember on duty use supplemental oxygen continuously during unpressurized Part 135 operations?
A.Above 10,000 feet MSL
B.Above 12,000 feet MSL
C.Above 14,000 feet MSL
D.Above 15,000 feet MSL
