2024 PRE-AREA SOLO EXAM WITHCORRECT ANSWERS
State the unit of measurements for: runway dimensions, temperature,
atmospheric pressure, weight, volume (liquids) and visibility? - CORRECT
ANSWERS-Runway Dimensions: Kilometres
Temperature: Degrees Celcius
Atmospheric Pressure: hPA (Hecta pascals)
Weight: kilograms
Volume: Litres
Visibility: Kilometres
Describe the meaning of kinetic and potential energy and the relationship to
basic aircraft operations? - CORRECT ANSWERS-Kinetic energy is the energy
any object possesses when in motion. Potential energy is the energy
possessed by a object by virtue of its position relative to others, stresses
within itself, electric charge, and other factors.
Describe the meaning of 'aircraft energy state' with respect to kinetic and
potential energy. - CORRECT ANSWERS-Aircraft energy state is the total or
sum of energy acting upon it. I.e. kinetic energy + potential energy
Describe the effects on 'aircraft energy state' of acceleration, deceleration,
climb and descent? - CORRECT ANSWERS-The aircraft energy state increases
whilst accelerating and in a climb whilst decreasing when in deceleration or
descent.
Describe the basic principle and function of a 'cylinder' in a four stroke cycle
internal combustion engine? - CORRECT ANSWERS-The cylinder forms part of
the chamber in which the fuel-air mixture is compressed and burned.
Describe the basic principle and function of a 'piston' in a four stroke cycle
internal combustion engine? - CORRECT ANSWERS-The piston moving within
the cylinder forms one of the walls of the combustion chamber.
Describe the basic principle and function of a 'piston rings' in a four stroke
cycle internal combustion engine? - CORRECT ANSWERS-Piston Rings seals
the piston in the cylinder, preventing any loss of power around sides of the
piston and passage of the oil into the combustion chamber.
Describe direction as three, two figures and clock code - CORRECT
ANSWERS-Three: 240
,Two: 06
Clock Code: 9 o'clock
How many ways can time be represented? - CORRECT ANSWERS-4 ways:
(AM/PM) 4 am
24-hour time (Hour-Minute): 1443
(Day-Hour-Minute): 301442
(Month-Day-Hour-Minute): 10301442
Also Greenwich Mean Time (GMT) has also been redesigned "Zulu Time''
What is a 'heading'? - CORRECT ANSWERS-A heading is the direction in which
the longitudinal axis the nose of the aeroplane is pointed
Describe the differences between the following terms when used to describe
direction: true, magnetic, compass - CORRECT ANSWERS-True Direction is
the direction measured with reference to true north (i.e., the direction of the
north geographical pole). Magnetic Direction is the direction measured with
reference to magnetic north. Variation is the difference between True and
Magnetic North. Compass Direction is the heading which uses also magnetic
north as a reference point but is susceptible to deviation as a consequence
of electrical fields formed by the aircraft
State the units used for navigation and visibility - CORRECT ANSWERS-
Degrees, minutes, seconds and kilometres
Define the meaning of knot (kt) when used to describe an aircraft's speed? -
CORRECT ANSWERS-Speed is stated in knot (kt) which is the number of
nautical miles travelled in one hour. The unit knot was derived to make
speed, distance and time all relative to each other. For example 60kt
groundspeed is 1nm/minute -so time equals.
Define Wind Velocity (W/V) - CORRECT ANSWERS-Wind velocity is the speed
and direction from which the wind is blowing expressed in knots and degrees
magnetic for the ATIS and degrees true for the area forecast
What does IAS mean? - CORRECT ANSWERS-Indicated Airspeed
What does CAS mean? - CORRECT ANSWERS-Calibrated Airspeed
What does TAS mean? - CORRECT ANSWERS-True Airspeed
What does GS mean? - CORRECT ANSWERS-Ground Speed
Express time in 24 hour time (4 figure group) - CORRECT ANSWERS-6 am =
0600 hrs
, 9 pm = 2100 hrs
Difference between UTC and local standard time? - CORRECT ANSWERS-UTC
when O hrs Sydney is +10hrs
State the units of measurement for and differentiate between: height,
altitude and elevation - CORRECT ANSWERS-All of these measurements are
measured in feet (ft). Height is the vertical displacement of an object AMSL.
Altitude is the vertical displacement of and object from the surface of the
Earth. Elevation is the vertical displacement of an aerodrome reference
AMSL.
Describe the basic principle and function of a 'inlet/exhaust valves' in a four
stroke cycle internal combustion engine? - CORRECT ANSWERS-The inlet
valve lets the fuel-air mixture into the cylinder. Whilst the exhaust valve lets
exhaust gases out of the cylinder after the combustion process.
Describe the basic principle and function of a 'connecting rod' in a four
stroke cycle internal combustion engine? - CORRECT ANSWERS-The
connecting rod forms a link between the piston and the crankshaft.
Describe the basic principle and function of a 'crank shaft' in a four stroke
cycle internal combustion engine? - CORRECT ANSWERS-The crankshaft
changes the straight line motion of the piston to a rotary turning motion. The
crankshaft also absorbs the power from all the cylinders and transfers it to
the propeller.
Describe the basic principle and function of a 'cam shaft' in a four stroke
cycle internal combustion engine? - CORRECT ANSWERS-The camshaft opens
and closes the inlet and exhaust valve to allow increased fuel-air induction
and to improve exhaust.
Describe the basic principle and function of a 'spark plugs' in a four stroke
cycle internal combustion engine? - CORRECT ANSWERS-Spark plugs ignite
the compressed fuel-air mixture.
Describe the effect of increasing altitude and temperature on engine
performance and how the following affect the power output of an engine
throttle lever position and the RPM. - CORRECT ANSWERS-Increasing
temperature and altitude will decrease the performance of the engine and
will therefore decrease both the power output of an engine and the RPM.
What is the function of the 'carburettor'? - CORRECT ANSWERS-The
carburettor's purpose is to mix fuel with air in the engine.
