Verified Answers |Latest Update |Already Graded A+
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...? ✔Correct Answer-loss of RPM
an abnormally high engine oil temp indication may be caused by ✔Correct Answer-the oil
level being too low
if the engine oil temp and cylinder head temperature gauges have exceeded their normal
operating range, the pilot may have been operating with...? ✔Correct Answer-too much
power and with the mixture set too lean
what change occurs in the fuel/air mixture when carburetor heat is applied? ✔Correct
Answer-the fuel/air mixture becomes richer
the basic purpose of adjusting the fuel/air mixture at altitude is to...? ✔Correct Answer-
decrease the fuel flow in order to compensate for decreased air density

degrees F and the relative humidity is above 80 percent
excessively high engine temperature, either in the air or on the ground, will...? ✔Correct
Answer-cause loss of power, excessive oil consumption, and possible permanent internal engine
damage
on aircraft equipped with fuel pumps, when is the auxiliary electric driven pump used?
✔Correct Answer-in the event engine-driven fuel pump fails
what is one of the advantages of an alternator over a generator in an airplane engine?
✔Correct Answer-the electrical output of an alternator is more constant throughout a wide
range of engine speeds
why do most standard certified aircraft incorporate a fuel ignition system with two individual
magnetos, separate sets of wires, and spark plugs? ✔Correct Answer-to increase reliability of
the ignition system
a disconnected ground wire from a magneto to the ignition switch...? ✔Correct Answer-could
allow the engine to continue to run after the ignition switch is turned off
what action can a pilot take to aid in cooling an engine that is overheating during a climb?
