An abnormal high engine oil temperature indication may be caused by
operating with a too high viscosity oil.
the oil level being too low.
operating with an excessively rich mixture.
At takeoff Cowl flaps should be selected:
open.
fully closed to decrease drag.
fully closed to increase drag.
If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with
too much power and with the mixture set too lean.
higher-than-normal oil pressure.
the mixture set too rich.
What action can a pilot take to aid in cooling an engine that is overheating during a climb?
Reduce climb speed and increase RPM.
Reduce rate of climb and increase airspeed.
Increase climb speed and increase RPM.
The primary purpose of a supercharger is to:
increase the mass of the charge entering the cylinder.
raise the temperature of the charge entering the cylinder.
Allow the use of high octane fuel.
The Manifold Pressure Gauge fitted to a supercharged engine measures:
The absolute pressure in the induction manifold.
The differential pressure across the supercharger compressor.
The pressure upstream of the throttle valve.
What is an advantage of a constant-speed propeller?
Provides a smoother operation with stable RPM and eliminates vibrations.
Permits the pilot to select the blade angle for the most efficient performance.
Permits the pilot to select and maintain a desired cruising speed.
For internal cooling, reciprocation aircraft engines are especially dependent on
the circulation of lubricating oil.
a properly functioning thermostat.
air flowing over the exhaust manifold.
An air/fuel ratio of 9:1 would be considered:
rich.
lean.
chamically correct.
