Air Cadet Aviation Exam Level 4 -Solved 2025
50 - ANSWER-The thickest part of a laminar flow airfoil occurs at __% of the chord.
Acceleration Error - ANSWER-On East-West headings, ACCELERATION will register a
turn towards North, and DECELERATION will register a turn towards South, this is an
error known as: ____________ _____.
Agoinic Lines - ANSWER-______ _____ join places of zero magnetic variation,
meaning that true north and magnetic north lie in a straight line relative to the locations
falling on an: ______ ____.
Air Mass - ANSWER-A large section of the troposphere with uniform properties of
temperature and moisture in the horizontal.
Airspeed Indicator - ANSWER-Relies on both pitot and static pressure. (hint: ASI)
Altimeter - ANSWER-Indicates altitude of aircraft.
Altimeter and Vertical Speed Indicator - ANSWER-Relies exclusively on static pressure.
Anabatic Wind - ANSWER-Occurs during the day when the slopes of the hills are
warmed. Air in contact with them becomes warmer and less dense and therefore flows
up the hill.
Angle of Incidence - ANSWER-The angle at which the wing is permanently inclined to
the longitudinal axis of the wing.
Aspect Ratio - ANSWER-The relationship between the length of the wing and its width,
calculated by dividing the wingspan by the average chord (Leading edge to trailing
edge).
Boundary Layer - ANSWER-The very thin layer of air lying over the surface of the wing.
Calibrated Airspeed - ANSWER-IAS corrected for position error (hint: CAS).
Cloud Formation - ANSWER-Contact with a surface through RADIATION, ADVECTION
over a colder surface, and EXPANSION brought about by lifting all contribute to: _____
_________.
Cold Air Mass - ANSWER-Instability, turbulence, good visibility, cumiliform clouds, and
precipitation in the form of SHOWERS, THUNDERSTORMS, and HAIL are
characteristics of a: ____ ___ ____.
Continental Air Mass - ANSWER-Very dry and little cloud development (Air mass).
, Cylinder Head Temperature Gauge - ANSWER-Indicates temperature of one or all
engine cylinder heads.
This shows the pilot the effectiveness of the engine cooling system.
High temperature indicate engine overload which can result in detonation.
Density Error - ANSWER-Temperature and pressure normally decrease when
increasing altitude, decreasing the density of air and causing the ASI to read less than
true airspeed. This is called: _______ _____.
Deviation - ANSWER-The slight deflection of the compass caused by surrounding metal
of the aircraft around a compass.
The compass, when affected, shows compass north. The difference between compass
north and magnetic north is called: _________.
Dewpoint - ANSWER-Condensation only occurs when the temperature reaches the:
________.
Equivalent Airspeed - ANSWER-CAS corrected for compressibility (hint: EAS).
Front - ANSWER-The transition zone between 2 air masses.
Fuel System - ANSWER-Fuel tank, fuel selector valve, fuel lines and filters, fuel quantity
gauge, and fuel primer are all components of the aircraft's: ____ ______.
Gravity Feed Fuel System - ANSWER-(TOP ONLY).
Great Circle - ANSWER-A circle on the surface of a sphere that passes through the
centre of the sphere, cutting it in half (Circumference of sphere).
A _____ ______ is a straight line.
Green - ANSWER-Normal Operating Range (Airspeed colour indication).
Gust - ANSWER-A rapid and irregular change in wind speed and may be associated
with
Indicated Airspeed - ANSWER-Uncorrected airspeed as read from the ASI (hint: IAS).
Isogonic Lines - ANSWER-________ _____ join places of zero magnetic variation.
Katabatic Wind - ANSWER-A down slope wind flowing from higher elevations down the
slope to the valleys below.
These generally occur during the night.
