A. formed by the longitudinal axis of the airplane and the chord line of the wing.
B. between the wing chord line and the relative wind.
C. between the airplane's climb angle and the horizon.
2. If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with
A. the mixture set too rich.
B. too much power and with the mixture set too lean.
C. higher-than-normal oil pressure.
3. 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. Taxi back to the flight line for a maintenance check.
B. Reduce manifold pressure to control detonation.
C. Check the results obtained with a leaner setting of the mixture.
4. While cruising at 9,500 feet msl, the fuel/air mixture is properly adjusted. What will occur if a descent to 4,500 feet msl is made without readjusting the mixture?
A. The excessively rich mixture will create higher cylinder head temperatures and may cause detonation.
B. The fuel/air mixture may become excessively lean.
C. There will be more fuel in the cylinders than is needed for normal combustion, and the excess fuel will absorb heat and cool the engine.
5. What change occurs in the fuel/air mixture when carburetor heat is applied?
A. A decrease in rpm results from the lean mixture.
B. The fuel/air mixture becomes richer.
C. The fuel/air mixture becomes leaner.
6. If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will most likely cause
A. detonation.
B. lower cylinder head temperatures.
C. a mixture of fuel and air that is not uniform in all cylinders.
7. Which would most likely cause the cylinder head temperature and engine oil temperature gauges to exceed their normal operating ranges?
A. Using fuel that has a lower-than-specified fuel rating.
B. Operating with higher-than-normal oil pressure.
C. Using fuel that has a higher-than-specified fuel rating.
8. An abnormally high engine oil temperature indication may be caused by
A. operating with a too-high viscosity oil.
B. operating with an excessively rich mixture.
C. the oil level's being too low.
9. Before starting each maneuver, pilots should
A. announce their intentions on the nearest CTAF.
B. visually scan the entire area for collision avoidance.
C. check altitude, airspeed, and heading indications.
10. Which operation would be de-scribed as preventive maintenance?
A. Alteration of main seat support brackets.
B. Engine adjustments to allow automotive gas to be used.
C. Servicing landing gear wheel bearings.
11. To best determine general forecast weather conditions over several states, the pilot should refer to an
A. Area Forecast.
B. Weather Depiction Chart.
C. Satellite Map.
