1. What is the primary purpose of the mixture control in a piston-engine
aircraft?
A. To control fuel flow to the engine based on altitude
B. To adjust airspeed during takeoff
C. To engage the propeller governor
D. To control cabin pressure
Answer: A
Rationale: The mixture control adjusts the fuel-to-air ratio delivered to the
engine, which is crucial for efficient engine operation at different altitudes,
preventing engine roughness and conserving fuel.
2. When flying under Visual Flight Rules (VFR), what minimum visibility is
required during daytime in Class E airspace below 10,000 feet MSL?
A. 1 mile
B. 3 miles
C. 5 miles
D. 7 miles
,Answer: B
Rationale: In Class E airspace below 10,000 feet MSL, VFR flight requires a
minimum of 3 miles visibility during the day to maintain safe separation from
clouds and other aircraft.
3. What does a steady green light from an airport control tower indicate
to an aircraft in flight?
A. Clear to land
B. Clear to take off
C. Return for landing
D. Exercise caution
Answer: A
Rationale: A steady green light from the tower to an aircraft in flight signals
that the aircraft is cleared to land, a standard visual signaling procedure.
4. Which instrument is primarily used to determine an aircraft’s rate of
climb or descent?
A. Altimeter
B. Vertical speed indicator (VSI)
C. Airspeed indicator
D. Heading indicator
Answer: B
Rationale: The vertical speed indicator measures the rate at which the
aircraft is climbing or descending, providing pilots with crucial information to
maintain desired altitude changes.
5. What is the primary cause of a spin in a light aircraft?
A. Engine failure at high altitude
B. Uncoordinated stall with yaw
,C. Excessive airspeed during descent
D. High-density altitude
Answer: B
Rationale: A spin occurs when one wing stalls more than the other due to
uncoordinated control inputs, producing autorotation and a steep, spiraling
descent.
6. During a preflight inspection, which action should be taken to ensure
proper operation of flight controls?
A. Check controls for full, free, and correct movement
B. Verify tire pressure only
C. Inspect engine oil levels
D. Confirm fuel quantity only
Answer: A
Rationale: Ensuring flight controls move freely and correctly is essential for
safe operation and maneuvering, which is a critical part of preflight checks.
7. What is the primary purpose of the rudder on an airplane?
A. Control roll
B. Control pitch
C. Control yaw
D. Control lift
Answer: C
Rationale: The rudder controls yaw, which is the left or right movement of
the aircraft nose around the vertical axis, aiding in coordinated turns and
crosswind landings.
8. If an aircraft has a maximum gross weight of 2,550 pounds and an
empty weight of 1,650 pounds, how much useful load is available?
, A. 850 pounds
B. 900 pounds
C. 1,000 pounds
D. 1,200 pounds
Answer: B
Rationale: Useful load is calculated by subtracting the empty weight from
the maximum gross weight: 2,550 − 1,650 = 900 pounds, which includes
passengers, cargo, and fuel.
9. What is the minimum safe altitude over congested areas according to
FAA regulations?
A. 500 feet above the highest obstacle
B. 1,000 feet above the highest obstacle within 2,000 feet horizontally
C. 1,500 feet above the ground
D. 2,000 feet above sea level
Answer: B
Rationale: FAA regulations require aircraft over congested areas to maintain
at least 1,000 feet above the highest obstacle within a 2,000-foot horizontal
radius to ensure safety.
10. Which document must a pilot always have on board an aircraft
when flying?
A. Aircraft flight manual, pilot certificate, and medical certificate
B. Aircraft insurance papers
C. Airport diagram
D. Air Traffic Control clearance
Answer: A
Rationale: FAA regulations mandate that a pilot must carry the aircraft’s
airworthiness certificate, registration, operating limitations, pilot certificate,
and medical certificate when operating an aircraft.
