B. May 31, two years later.
C. May 3, one year later.
2. The basic purpose of adjusting the fuel/air mixture at altitude is to

B. increase the amount of fuel in the mixture to compensate for the decrease in pressure and the density of the air.
C. decrease the fuel flow in order to compensate for decreased air density.
3. Which cruising altitude is appropriate for a VFR flight on a magnetic course of 135 degrees?
A. Even thousands plus 500 feet.
B. Odd thousands plus 500 feet.

A. small temperature/dew point spread.
B. stratiform clouds.
C. visible moisture.
5. A first class medical certificate is issued to a 36-year-old pilot on August 10, this year. To exercise the privileges of a private pilot certificate, the medical certificate will be valid until midnight on
A. August 31, three years later.
B. August 31, five years later.
C. August 10, two years later.
6. During the runup at a high-elevation airport, a pilot notes a slight engine roughness that is not affected by the magneto check but grows worse during the carburetor heat check. Under these circumstances, what would be the most logical initial action?
A. Check the results obtained with a leaner setting of the mixture.
B. Reduce manifold pressure to control detonation.
C. Taxi back to the flight line for a maintenance check.
7. If an aircraft is equipped with a fixed-pitch propeller and a float-type carburetor, the first indication of carburetor ice would most likely be
A. engine roughness.
B. a drop in oil temperature and cylinder head temperature.
C. loss of rpm.
8. The takeoffs and landings required to meet the recency of experience requirements for carrying passengers in a tailwheel airplane
A. may be touch and go or full stop.
B. must be to a full stop.
C. must be touch and go.
Final Exam Answers
1. The correct answer is B. FAR 61.23 details the duration of medical certificates. If the airman is age 40 or older when issued, the third class medical certificate is valid for 24 calendar months.
2. The correct answer is C. Less fuel is required at higher altitudes, so the mixture may be leaned to compensate for the decreased air density. (Pilot’s Handbook of Aeronautical Knowledge)
3. The correct answer is B. On magnetic courses of 0 through 179 degrees, odd thousands plus 500 feet are appropriate for operating an aircraft under VFR in level cruising flight more than 3,000 feet above the surface. Select 3,500, 5,500, 7,500, et cetera. (FAR 91.159)
4. The correct answer is C. Whether in the form of clouds or precipitation, visible moisture is necessary for the formation of aircraft structural ice. (Pilot’s Handbook of Aeronautical Knowledge)
5. The correct answer is B. FAR 61.23 details the duration of medical certificates. If the airman is under age 40 when issued, the first class medical certificate is valid for 60 calendar months.
6. The correct answer is A. The likely cause of roughness is the rich mixture, which will then be exacerbated by applying carburetor heat. Leaning the mixture during the runup will normally resolve this problem. If this initial fix does not work, then maintenance may be required. (Pilot’s Handbook of Aeronautical Knowledge)
7. The correct answer is C. At a constant power setting, loss of rpm with no throttle adjustment by the pilot could be the first indication of carburetor ice, followed later by engine roughness. Apply full carburetor heat to remove any suspected ice. An initial further drop in rpm would be normal, and then a noted increase in power with a corresponding smoother-running engine would confirm the ice had been removed. (Pilot’s Handbook of Aeronautical Knowledge)
8. The correct answer is B. Passenger-carrying currency obtained in a tailwheel airplane must include three takeoffs and three landings to a full stop, done within the preceding 90 days. (FAR 61.57)
