1. Question: What is the greatest vortex strength generated by an aircraft?
• Answer: The greatest vortex strength occurs when the generating
aircraft is heavy, clean, and slow.
• Explanation: The strength of the vortex is influenced by the aircraft’s
weight, speed, and wing shape. The vortex is strongest when the aircraft
is heavy, clean (with no external attachments or drag-inducing factors),
and slow, as these conditions produce the most powerful vortex.
2. Question: If an airplane weighs 4,500 pounds, what approximate weight
would the airplane structure be required to support during a 45° banked turn
while maintaining altitude?
• Answer: 6,750 pounds.
• Explanation: In a banked turn, the load factor increases. The weight of
the aircraft in a 45° banked turn will be multiplied by a factor of 1.41
(which is the square root of 2). Therefore, the weight supported during a
45° turn is 4,500 pounds × 1.41 ≈ 6,750 pounds.
3. Question: What is the term "angle of attack" defined as?
• Answer: The angle of attack is the angle between the chord line of the
wing and the relative wind.
, • Explanation: The angle of attack is a critical factor in determining how
air flows over the wing. It is the angle between the wing's chord line (the
straight line connecting the leading edge to the trailing edge) and the
direction of the incoming airflow (relative wind).
4. Question: If the grade of fuel used in an aircraft engine is lower than
specified for the engine, what is most likely to occur?
• Answer: Detonation.
• Explanation: Using a lower-grade fuel can lead to detonation, which is
an uncontrolled explosion of the fuel-air mixture in the engine. This
causes a sudden increase in pressure and temperature, which can
damage the engine and result in poor performance.
5. Question: Who is primarily responsible for maintaining an aircraft in
airworthy condition?
• Answer: Owner or operator.
• Explanation: According to 14 CFR Part 91, the owner or operator is
responsible for ensuring that the aircraft is maintained in an airworthy
condition. This responsibility includes ensuring that the aircraft
complies with all maintenance and operational requirements.
6. Question: 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. When will the compass show an error?
• Answer: When on an east or west heading.
, • Explanation: On an east or west heading, acceleration or deceleration
causes errors in the magnetic compass, leading to the indication of a
turn toward the north when accelerating and a turn to the south when
decelerating. This error does not occur on north or south headings,
where the compass will behave correctly.
7. Question: What is the proper adjustment to make on the attitude indicator
during level flight?
• Answer: Align the miniature airplane to the horizon bar.
• Explanation: The miniature airplane on the attitude indicator should be
adjusted so that the wings align with the horizon bar when the aircraft is
in straight-and-level flight. This ensures the indicator reflects the
aircraft's true orientation relative to the horizon.
8. Question: Which color identifies the power-off stalling speed in a specified
configuration on an airspeed indicator?
• Answer: Lower limit of the green arc.
• Explanation: The green arc on the airspeed indicator represents the
normal operating range. The lower limit of this arc is the power-off
stalling speed (V_s1) in a specified configuration. It is the speed below
which the aircraft cannot maintain level flight.
9. Question: What action should the pilots of a glider and an airplane take if
on a head-on collision course?
• Answer: Both pilots should give way to the right.
