1. Which condition is most favorable to the development of carburetor icing?
A. Temperature between 32 and 50 degrees Fahrenheit and low humidity.
B. Temperature between 20 and 70 degrees F and high humidity.
C. Any temperature below freezing and a relative humidity of less than 50 percent.
2. One in-flight condition necessary for structural icing to form is
A. the presence of stratiform clouds.
B. a small temperature/dew-point spread.
C. visible moisture.
3. To determine the freezing level and areas of probable icing aloft, the pilot should refer to the
A. Area Forecast.
B. Radar Summary Chart.
C. Weather Depiction Chart.
4. What change occurs in the fuel/air mixture when carburetor heat is applied?
A. The fuel/air mixture becomes richer.
B. The fuel/air mixture becomes leaner.
C. A decrease in RPM results from the lean mixture.
5. If a pilot suspects that the engine (with a fixed-pitch propeller) is detonating during climbout after takeoff, the initial corrective action to take would be to
A. lean the mixture.
B. lower the nose slightly to increase airspeed.
C. apply carburetor heat.
6. If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with
A. too much power and with the mixture set too lean.
B. the mixture set too rich.
C. higher-than-normal oil pressure.
7. The takeoffs and landings required to meet the recency-of-experience requirements for carrying passengers in a tailwheel airplane
A. must be touch and go.
B. must be to a full stop.
C. may be touch and go or full stop.
8. The operating principle of float-type carburetors is based on the
A. automatic metering of air at the venturi as the aircraft gains altitude.
B. increase in air velocity in the throat of a venturi, causing an increase in air pressure.
C. difference in air pressure at the venturi throat and the air inlet.
9. The basic purpose of adjusting the fuel/air mixture at altitude is to
A. increase the amount of fuel in the mixture to compensate for the decrease in pressure and density of the air.
B. decrease the amount of fuel in the mixture to compensate for increased air density.
C. decrease the fuel flow in order to compensate for decreased air density.
10. Transcribed Weather Broadcasts (TWEBs) may be monitored by tuning the appropriate radio receiver to certain
A. VOR and NDB frequencies.
B. airport advisory frequencies.
C. ATIS frequencies.
11. With respect to the certification of airmen, which are categories of aircraft?
A. Airplane, rotorcraft, glider, lighter-than-air.
B. Single-engine land and sea, multiengine land and sea.
C. Gyroplane, helicopter, airship, free balloon.
