With respect to the certification of airmen, which is a category of aircraft? correct
answers Airplane, rotorcraft, glider, lighter-than-air. Airmen are certificated according to
five categories of aircraft: airplane, rotorcraft, glider, lighter-than-air, and new category,
powered lift. Gyroplane and helicopter are classes of aircraft within the rotorcraft
category. Airship and balloon are classes of aircraft within the lighter-than-air category.
SIngle-engine land and sea and multiengine land and sea are the four classes withing
the airplane category.
With respect to the certification of airmen, which is a class of aircraft?
A. Airplane, rotorcraft, glider, lighter-than-air
B. Single-engine land and sea, multiengine land and sea.
C. Lighter-than-air, airship, hot air balloon, gas balloon correct answers . Each category
of aircraft is broken down into classes. The airplane category is divided into single-
engine land and sea, and multi-engine land and sea.
With respect to the certification of aircraft, which is a category of aircraft? correct
answers Normal, utility, and acrobatic are three of the categories under which aircraft
are certified, based on their construction and use. Airplane, rotorcraft, and glider are
categories of aircraft with respect to certification of AIRMEN. Landplane and seaplane
are common, but incomplete, descriptions of CLASSES of airplane based on airmen
certification.
With respect to the certification of aircraft, which is a class of aircraft? correct answers
As per the definition in FAR 1.1 "class" when used with respect to the certification of
aircraft, is a broad grouping of aircraft having similar means of flight, propulsion or
landing. These classes include: airplane, rotorcraft, glider, balloon, and powered lift. In
reality, class is not used as a designator in aircraft certification.
How soon after the conviction for driving while intoxicated by alcohol or drugs shall it be
reported to the FAA, Civil Aviation Security Division? correct answers No later than 60
days after the motor vehicle action.
According to 91.15, certificated pilots must provide report of each motor vehicle action
to the FAA no later than 60 days after the action.
Where may an aircraft's operating limitations be found? correct answers In the current,
FAA-approved flight manual, approved manual material, markings, and placards, or any
combination thereof. Operating limits can be found in any of these sources.
To minimize the side loads placed on the landing gear during touchdown, the pilot
should keep the correct answers Longitudinal axis of the aircraft parallel to the direction
,of its motion. Keeping the longitudinal axis parallel to the direction of motion ensures
that the main gear will touchdown and roll as designated, parallel to the aircraft's
direction of travel. Side loading the gear is not only bad for the aircraft structurally, but
can result in the aircraft rolling away from the runway centerline on touchdown.
Where may an aircraft's operating limitations be found if the aircraft has an
Experimental or Special light-sport airworthiness certificate? correct answers Operating
limitations for experimental aircraft are actually part of Form 8130-7, which is the special
airworthiness certificate. As with all airworthiness certificates, this one must be carried
in the aircraft, which ensures the operating limitations of an experimental or light sport
aircraft are available to the PIC.
Excessively high engine temperatures will correct answers Cause loss of power,
excessive oil consumption, and possible permanent internal engine damage. High
temperature can cause detonation and a resulting loss of power, excessive oil
consumption, and engine damage, including scoring of the cylinders and damage to
pistons, rings, and valves.
If the engine oil temperature and cylinder head temperature gauges have exceeded
their normal operating range, the pilot may be been operating with correct answers Too
much power and with the mixture set too lean. With high power settings and the mixture
set too lean, overheating can result. This can be indicated by a high engine oil
temperature and cylinder head temperature.
One purpose of the dual ignition system on an aircraft engine is to provide for correct
answers Improved engine performance. Dual ignition systems fire two spark plugs,
which improves combustion of the fuel/air mixture and results in slightly more power.
On aircraft equipped with fuel pumps, when is the auxillary electric driven pump used?
correct answers In the event engine-driven fuel pump fails. The auxillary electric pump
is a backup for an engine-driven pump. Although labeling, procedures for use, and
control switches differ between manufacturers, these auxillary pumps can cause
operational problems if used inappropriately. In some systems, continuous use of both
the auxillary pump and the engine-driven pump can function, auxillary pumps are
commonly used to provide fuel under pressure for engine starting.
The operating principle of float-type carburetors is based on the correct answers
Difference in air pressure at the venturi throat and the air inlet. The decreased pressure
caused by air flowing rapidly through the venturi tube draws fuel from the float chamber.
The pasic purpose of adjusting the fuel/air mixture at altitude is to correct answers
Decrease the fuel flow in order to compensate for decreased air density. If fuel flow is
not increased with altitude, the mixture becomes too rich with fuel. Therefore, the fuel
mixture must be learned to maintain the proper fuel/air ratio.
,During the run-up 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? correct
answers Check the results obtained with a leaner setting of the mixture. In this case,
engine roughness is probably caused by the mixture set too rich for the high altitude.
When the carburetor heat is turned on, the warmer air entering the carburetor is less
dense, and the mixture is further enriched. As a result, the engine roughness increases.
The problem can usually be corrected by leaning the mixture.
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? correct
answers The fuel/air mixture may become excessively lean. With decrease in altitude,
air density increases. This means you will have to enrich the mixture as you descend,
otherwise the fuel/air mixture can become excessively lean.
Which condition is most favorable to the development of carburetor icing? correct
answers Temperaure between 20 and 70F and high humidity.
Carburetor icing is most likely between 20 and 70F in high humidity conditions.
The possibility of carburetor icing exists even when the ambient air temperature is as
correct answers high as 70F and the relative humidity is high. Carburetor icing is most
probable between 20 and 70F with high humidity or visible moisture.
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 answers Loss of RPM. The
restricted airflow through the carburetor causes an enriched mixture and loss of RPM.
Applying carburetor heat will correct answers enrich the fuel/air mixture. When the
carburetor heat is turned on, the warmer air entering the carburetor is less dense, and
the mixture is enriched.
What change occurs in the fuel/air mixture when carburetor heat is applied? correct
answers The fuel/air mixture becomes richer. When the carburetor heat is turned on,
the warmer air entering the carburetor is less dense, and the mixture is enriched.
Generally speaking, the use of carburetor heat tends to correct answers Decrease
engine performance. Since the warmer air entering the carburetor is less dense, the
fuel/air mixture is enriched and power is decreased.
The presence of carburetor ice in an aircraft equipped with a fixed-pitch propeller can be
verified by applying carburetor heat and noting correct answers a decrease in RPM and
then a gradual increase in RPM.. WHen carburetor heat is first applied, the mixture is
enriched, and RPM decreases. Then, as the ice melts, airflow into the carburetor
increases, leaning the mixture and RPM increases.
, With regard to carburetor ice, float-type carburetors systems in comparison to fuel
injection systems are generally considered to be correct answers more susceptible to
icing. Because fuel injection systems do not have a venturi throat, they are not as
susceptible to icing as float-type carburetors.
If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will
most likely cause correct answers detonation. The higher the grade of fuel, the more
pressure it can withstand without detonating. Conversely, lower fuel grades are more
prone to detonation.
Detonation occurs in a reciprocating aircraft engine when correct answers the
unburned charge in the cylinders explodes instead of burning normally.. Detonation
occurs when the fule/air mixture suddenly explodes in the cylinders instead of burning
smoothly.
Detonation may occur in high-power settings when correct answers the fuel mixture
ignites instantaneously instead of burning progressively and evenly.. Detonation occurs
when the fuel/air mixture suddenly explodes in the cylinders instead of burning
smoothly. Detonation is caused by excessively lean mixtures while hot spots in the
cylinder describes pre-ignition.
If a pilot suspects that the engine (with a fixed-pitch propeller) is detonating during
climb-out after takeoff, the initial corrective action to take would be to correct answers
lower the nose slightly to increase airspeed. Detonation can occur when teh engine
overheats. One action to help cool the engine is to increase airspeed, thus increasing
the cooling airflow around the engine.
The uncontrolled firing fo the fuel/air charge in advance of normal spark ignition is
known as correct answers Pre-ignition occurs when the fuel/air mixture ignites too
soon.
Which would most likely cause the cylinder head temperature and engine oil
temperature gauges to exceed their normal operating ranges? correct answers Using
fuel that has a lower-than-specified fuel rating. Lower grade fuels will detonate under
less pressure. Using a lower fuel rating than specified can cause excessive engine
temperatures.
What type fuel can be subsitituted for an aircraft if teh recommended octane is not
available? correct answers The next higher octane aviation gas. If the manufacturer's
recommendations are followed, the next higher grade of fuel may normally be used.
Filling the fuel tanks after the last flight of the day is considered a good operating
procedure because this will correct answers Prevent moisture condensation by
eliminating airspace in tanks. As the airplane cools overnight, water condenses in the
tanks from vapor in the air and enters the fuel. Filing the tanks eliminates the air space
and prevents condensation.
