Chapter 2 Flashcards
In the northern hemisphere, a magnetic compass will normally indicate a turn toward the north if
an aircraft is accelerate while on an east or west heading
Deviation in a magnetic compass is caused by the
magnetic fields within the aircraft distorting the lines of magnetic force
During flight, when are the indications of a magnetic compass acurate?
only in straight and level unaccelerated flight
Deviation error of the magnetic compass is caused by
certain metals and electrical systems within the aircraft
In the northern hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate
correctly when on a north or south heading
In the northern hemisphere, a magnetic compass will normally indicate initially a turn toward the west if
a right turn is entered from a north heading
In the northern hemisphere, the magnetic compass will normally indicate a turn towards the south when
the aircraft is decelerated while on a west heading
What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a south heading in the Northern Hemisphere
yhe compass will indicate a turn to the right, but at a faster rate than is actually occurring
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn towards the east if
a left turn is entered from a north heading

What is absolute altitude
the vertical distance of the aircraft above the surface
What is density altitude
the pressure altitude corrected for nonstandard temperature
What is pressure altitude
the altitude indicated when the barometric pressure scale is set to 29.92
Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates
true altitude at field elevation
Under what condition is the indicated altitude the same as the true altitude
when at sea level under standard conditions
Under what condition is the pressure altitude and density altitude the same value
at standard temperature
Under which condition will pressure altitude be equal to true altitude
when standard atmospheric conditions exist
If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs
700-foot increase in indicated altitude
If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication
altimeter will indicate 150 feet lower
If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate
lower than the actual altitude above sea level
If a flight is made from an area of high pressure into an area of lower pressure without the altimeter setting being adjusted, the altimeter will indicate
higher than the actual altitude above sea level
Which condition would cause the altimeter to indicate a lower altitude than true altitude
air temperature warmer than standard
Under which condition will true altitude be lower than indicated altitude
in colder than standard air temperature
How do variations in temperature affect the altimeter
pressure levels are raised on warm days and the indicated altitude is lower than true altitude
A turn coordinator provides an indication of the
movement of the aircraft about the yaw and roll axes
To receive accurate indications during flight from a heading indicator, the instrument must be
periodically realigned with the magnetic compass as the gyro precesses
The proper adjustment to make on the attitude indicator during level flight is to align the
miniature airplane to the horizon bar
How should a pilot determine the direction of bank from an attitude indicator
by the relationship of the miniature airplane to the deflected horizon bar
What is the benefit of flying with a glass cockpit
situational awareness is increased
What steps must be taken when flying with glass cockpits to ensure safe flight
regularly scan both inside and outside, use all appropriate checklists, and cross-check with other forms of information
An aircraft which is equipped with an Electronic Flight Display can
offer new capabilities and simplify the basic flying task
You are flying an aircraft equipped with an electronic flight display and the air data computer fails. What instrument is affected
airspeed indicator
An abnormally high engine oil temperature indication may be caused by
the oil level being too low
Excessively high engine temperatures will
cause loss of power, excessive oil consumption, and possible permanent internal engine damage
Excessively high engine temperatures, either in the air or on the ground, will
cause loss of power, excessive oil consumption, and possible permanent internal engine damage
For internal cooling, air cooled engines are specially dependent on
the circulation of lubricating oil
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
What action can a pilot take to aid in cooling an engine that is overheating during a climb
reduce rate of climb and increase airspeed
what is one procedure to aid in cooling an engine that is overheating
enrich the fuel mixture
How is engine operation controlled on an engine equipped with a constant-speed propeller
the throttle controls power output as registered on the manifold pressure gauges and the propeller control regulates engine RPM
A precaution for the operation of an engine equipped with a constant-speed propeller is to
avoid high manifold pressure settings with low RPM
What is an advantage of a constant-speed propeller
permits the pilot to select the blade angle for the most efficient performance
One purpose of the dual ignition system on an aircraft engine is to provide for
improved engine performance
If the ignition switch ground wire becomes disconnected, the magneto
may continue to fire
The reason a 4-cylinder reciprocating engine continues to run after the ignition switch is positioned to OFF may be a
broken magneto ground wire
With regard to carburetor ice, float-type carburetor systems in comparison to fuel injection systems are generally considered to be
more susceptible to icing
Which condition is most favorable to the development of carburetor icing
temperature between 20F and 70F and high humidity
The possibility of carburetor icing exists even when the ambient air temperature is
as high as 70F and the relative humidity is high
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
decrease of RPM
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
loss of RPM
The operating principles of float-type carburetors is based on the
difference in air pressure at the venturi throat and the air inlet
The presence of carburetor ice in an aircraft equipped with a fixed-pitch propeller can be verified by applying carburetor heat and noting a
decrease in RPM and then a gradual increase in RPM
Generally speaking, the use of carburetor heat tends to
decrease engine performance

Should it become necessary to handprop an airplane engine, it is extremely important that a competent pilot
be at the controls on the flight deck
During preflight in cold weather, crankcase breather lines should receive special attention because they are susceptible to being clogged by
