FAA Private Pilot Airplane (PAR) Knowledge Test — Student Pilot Certificate — Questions and Answers
Question 1: What is the result of leaning the mixture too aggressively at low altitude?
- Lower cylinder head temperatures and reduced wear
- Engine roughness, loss of power, and possible detonation (Correct answer)
- Smoother engine operation and improved fuel economy
- Increased manifold pressure and higher RPM
Correct answer: Engine roughness, loss of power, and possible detonation
An excessively lean mixture can cause rough running, power loss, and dangerously high cylinder temperatures that may lead to detonation.
Question 2: A student pilot must receive a logbook endorsement from a CFI before flying solo in:
- Any airspace that requires communication with ATC (Correct answer)
- Class D airspace
- Class G airspace only
- Class E airspace above 1,200 feet AGL
Correct answer: Any airspace that requires communication with ATC
FAR 61.95 requires a CFI endorsement for solo flight in any controlled airspace, which includes Class B, C, D, and some Class E.
Question 3: What is 'form drag' caused by?
- Skin friction along a smooth surface
- Lift generation at high angles of attack
- Pressure differences created at wingtips
- The shape of an object disrupting airflow and creating turbulent wake (Correct answer)
Correct answer: The shape of an object disrupting airflow and creating turbulent wake
Form drag results from the shape of an object separating airflow and creating a low-pressure turbulent wake behind it.
Question 4: When departing from a non-towered airport, which traffic pattern direction should a pilot use if not specified by NOTAMs or the Chart Supplement?
- Left-hand traffic pattern (Correct answer)
- Right-hand traffic pattern
- Straight-out departure only
- Either direction is acceptable
Correct answer: Left-hand traffic pattern
Left-hand traffic patterns are standard at non-towered airports unless the Chart Supplement or a NOTAM specifies right-hand traffic.
Question 5: What is 'ground effect' and how does it affect landing?
- Turbulence caused by wind shear near the ground that increases landing distance
- Static buildup from the runway surface that affects avionics
- Increased lift caused by runway heat that makes landings easier
- Reduced induced drag when flying close to the ground that can cause the aircraft to float (Correct answer)
Correct answer: Reduced induced drag when flying close to the ground that can cause the aircraft to float
Ground effect reduces induced drag within one wingspan of the ground, causing the aircraft to 'float' past the intended touchdown point.
Question 6: What action should a student pilot take when a NOTAM or weather advisory indicates a TFR (Temporary Flight Restriction) along the planned route?
- TFRs apply only to IFR flights — VFR student pilots are exempt
- Contact the nearest FSS in-flight and request passage
- Avoid the TFR unless specific authorization has been obtained from the controlling agency (Correct answer)
- Proceed through at or above 3,000 feet AGL since TFRs apply only to the surface
Correct answer: Avoid the TFR unless specific authorization has been obtained from the controlling agency
TFRs prohibit all flight within the restricted area unless the pilot has received explicit authorization from the designated controlling agency; violation can result in certificate action and interception.
Question 7: What is required to enter Class C airspace?
- Permission from FSS
- IFR clearance
- Two-way communication and Mode C (Correct answer)
- Flight plan
Correct answer: Two-way communication and Mode C
Pilots must establish two-way radio communication and have a Mode C transponder to enter Class C airspace.
Question 8: What transponder code should be squawked when a pilot experiences a radio failure in VFR conditions?
- 7500
- 7700
- 1200
- 7600 (Correct answer)
Correct answer: 7600
Squawk 7600 indicates loss of radio communication, alerting ATC that the pilot cannot receive transmissions.
Question 9: Which of the following describes the relationship between airspeed, angle of attack (AOA), and lift in straight-and-level flight?
- To maintain constant lift, if airspeed decreases, the angle of attack must increase. (Correct answer)
- Lift is independent of both airspeed and angle of attack.
- To maintain constant lift, if airspeed increases, the angle of attack must also increase.
- Angle of attack and airspeed must be held constant to maintain a specific amount of lift.
Correct answer: To maintain constant lift, if airspeed decreases, the angle of attack must increase.
In straight-and-level flight, lift must equal weight. Lift is generated by the movement of air over the wings. If the aircraft slows down (airspeed decreases), the wing must be presented to the oncoming air at a higher angle of attack to generate the same amount of lift required to counteract weight.
Question 10: What does 'SIGMET' stand for and what type of weather does it cover?
- Significant Meteorological Information; covers severe or extreme weather hazardous to all aircraft (Correct answer)
- Systematic General Meteorological Information; covers general weather forecasts
- Special Instrument Meteorological Environment Training; covers IFR weather
- Significant Ground Meteorological Temperature; covers frost and icing conditions
Correct answer: Significant Meteorological Information; covers severe or extreme weather hazardous to all aircraft
A SIGMET (Significant Meteorological Information) warns of severe or extreme weather such as turbulence, icing, and volcanic ash hazardous to all aircraft.
Question 11: Which condition increases the risk of carburetor ice formation most significantly?
- Very cold, dry air below -20°F with clear skies
- Temperatures between 20°F and 70°F with visible moisture or high humidity (Correct answer)
- Hot summer days with temperatures above 90°F
- High-altitude cruise in clear air above the clouds
Correct answer: Temperatures between 20°F and 70°F with visible moisture or high humidity
Carburetor icing is most likely between 20°F and 70°F when moisture is present, as the venturi cooling effect can drop temperatures well below freezing.
Question 12: What does a flashing white light signal from the tower mean to an aircraft on the ground?
- Proceed to the runway
- Taxi toward the control tower
- Stop immediately
- Return to starting point on the airport (Correct answer)
Correct answer: Return to starting point on the airport
A flashing white light directed at an aircraft on the ground means 'return to starting point on the airport.'
Question 13: A pilot flying at night notices that looking directly at a dim light makes it disappear. This phenomenon is called:
- Central blind spot effect (Correct answer)
- Empty-field myopia
- Autokinesis
- Night myopia
Correct answer: Central blind spot effect
The center of the retina (fovea) has few rod cells, creating a central blind spot at night; objects become visible when viewed slightly off-center (off-axis viewing).
Question 14: An altimeter is a flight instrument that measures an aircraft's:
- Attitude relative to the horizon.
- Height above a specific pressure level. (Correct answer)
- Speed through the air.
- Vertical speed or rate of climb/descent.
Correct answer: Height above a specific pressure level.
An altimeter is essentially a sensitive barometer that measures atmospheric pressure. It is calibrated to show this pressure measurement as an altitude, typically height above Mean Sea Level (MSL), based on a standard pressure lapse rate.
Question 15: During an emergency approach to an off-airport landing, what field characteristics should a pilot prioritize?
- Longest possible field regardless of obstacles
- Field closest to a road for easy rescue access
- Smooth surface into the wind with no obstacles on final approach (Correct answer)
- Field that is illuminated by sunlight for best visibility
Correct answer: Smooth surface into the wind with no obstacles on final approach
Landing into the wind reduces groundspeed at touchdown, and obstacle-free approach paths reduce collision risk.
Question 16: A NOTAM (Notice to Airmen) about a closed taxiway is classified as what type of NOTAM?
- Pointer NOTAM
- FDC NOTAM
- NOTAM (D) (Correct answer)
- Military NOTAM
Correct answer: NOTAM (D)
NOTAMs containing airport and facility information, such as taxiway closures, are classified as NOTAM (D) — Distant NOTAMs.
Question 17: A Temporary Flight Restriction (TFR) is most commonly issued to:
- Protect airspace around special events, disasters, or VIPs (Correct answer)
- Designate permanent military training areas
- Mark boundaries of Class E airspace
- Define MOA activation times
Correct answer: Protect airspace around special events, disasters, or VIPs
TFRs are temporary airspace restrictions typically protecting sporting events, disaster areas, or presidential movements.
Question 18: What does a steady green light signal mean when directed at an aircraft in flight?
- Give way to other aircraft
- Proceed to the next checkpoint
- Return for landing
- Cleared to land (Correct answer)
Correct answer: Cleared to land
A steady green light directed at an aircraft in flight means cleared to land.
Question 19: Which of the following is a limitation that a CFI may place in a student pilot's logbook endorsement for local solo flights?
- Neither — endorsements are standardized by the FAA
- The number of touch-and-go landings per session
- Maximum altitude the student may fly
- Both maximum altitude and weather minimums (Correct answer)
Correct answer: Both maximum altitude and weather minimums
FAR 61.87 allows a CFI to specify limitations such as weather minimums, altitude restrictions, and other conditions appropriate for that specific student.
Question 20: What is the maximum speed when operating within Class D airspace surface area?
- 200 knots (Correct answer)
- 250 knots
- 156 knots
- No specific speed limit applies
Correct answer: 200 knots
FAR 91.117 limits speed to 200 knots indicated airspeed in Class D airspace surface areas.
Question 21: What is the purpose of the aircraft's ELT (Emergency Locator Transmitter)?
- To automatically transmit a distress signal on 406 MHz after a crash to aid search and rescue (Correct answer)
- To communicate with ATC on emergency frequencies during flight
- To broadcast the aircraft's position continuously during all phases of flight
- To send a text alert to the pilot's phone if the aircraft is stolen
Correct answer: To automatically transmit a distress signal on 406 MHz after a crash to aid search and rescue
An ELT activates upon impact and transmits a coded signal to satellites on 406 MHz, enabling search and rescue teams to locate a downed aircraft.
Question 22: What does a blocked static port cause on the airspeed indicator?
- The airspeed indicator reads higher than actual speed
- The airspeed indicator reads lower than actual speed
- The airspeed indicator freezes at the reading present when the port became blocked (Correct answer)
- The airspeed indicator reads zero because no pressure differential exists
Correct answer: The airspeed indicator freezes at the reading present when the port became blocked
A blocked static port traps the reference pressure at the altitude of blockage, causing the airspeed to freeze and not reflect actual changes in speed.
Question 23: Aspect ratio of a wing is defined as the ratio of:
- Lift to drag coefficient
- Chord length to wing thickness
- Wing area to fuselage length
- Wingspan to chord length (Correct answer)
Correct answer: Wingspan to chord length
Aspect ratio is the ratio of the wingspan (or span squared) to the mean chord, indicating how long and narrow the wing is.
Question 24: What is the definition of 'Vx' and when would a student pilot use it?
- Maximum structural cruising speed; used for maximum efficiency
- Maneuvering speed; used in turbulent air to protect the airframe
- Best rate of climb speed; used for normal climb to cruise altitude
- Best angle of climb speed; used to clear obstacles after takeoff (Correct answer)
Correct answer: Best angle of climb speed; used to clear obstacles after takeoff
Vx is best angle of climb speed and provides the greatest altitude gain over the shortest horizontal distance, useful for clearing obstacles.
Question 25: What is the primary purpose of a PIREP (Pilot Weather Report)?
- To report in-flight weather conditions observed by pilots (Correct answer)
- To file a flight plan with ATC
- To request a weather deviation from ATC
- To cancel an IFR flight plan
Correct answer: To report in-flight weather conditions observed by pilots
A PIREP is a report made by a pilot describing actual weather conditions encountered during flight, which ATC and other pilots can use.
Question 26: At what altitude does a normally aspirated engine lose approximately 3% of its power for every 1,000 feet gained?
- Only above the critical altitude
- Above 10,000 feet MSL only
- From sea level upward (Correct answer)
- Above 5,000 feet MSL only
Correct answer: From sea level upward
A normally aspirated engine loses roughly 3% of its rated power for each 1,000 feet of altitude gain starting from sea level.
Question 27: What does a displaced threshold on a runway mean for landing aircraft?
- Landing must begin at or beyond the displaced threshold (Correct answer)
- The runway is closed beyond that point
- The area before the displaced threshold is only usable for helicopter operations
- Landing before the displaced threshold is permitted but the area cannot be used for takeoff roll
Correct answer: Landing must begin at or beyond the displaced threshold
A displaced threshold means the landing threshold is moved from the runway's physical beginning; pilots must touch down at or beyond the displaced threshold markings.
Question 28: What is the minimum safe altitude over a congested area?
- 2,000 feet MSL
- 500 feet AGL
- 300 feet AGL
- 1,000 feet above highest obstacle (Correct answer)
Correct answer: 1,000 feet above highest obstacle
Federal Aviation Regulations require a minimum of 1,000 feet above the highest obstacle over congested areas.
Question 29: A pilot is on final approach for landing and extends the flaps. What is the primary aerodynamic reason for using flaps during this phase of flight?
- To reduce the overall weight of the aircraft.
- To decrease the angle of attack and increase landing speed.
- To increase the wingspan for better roll control.
- To allow the aircraft to fly at a slower airspeed while maintaining sufficient lift. (Correct answer)
Correct answer: To allow the aircraft to fly at a slower airspeed while maintaining sufficient lift.
Extending flaps increases the wing's camber and, in some cases, its surface area. This allows the wing to produce the required lift at a lower airspeed, enabling a slower and steeper approach for landing.
Question 30: The term 'relative wind' refers to:
- The direction and speed of the actual wind aloft
- The airflow direction relative to the moving aircraft, opposite to the flight path (Correct answer)
- Wind reported at the nearest weather station
- Headwind component on landing
Correct answer: The airflow direction relative to the moving aircraft, opposite to the flight path
Relative wind is the airflow experienced by the aircraft as a result of its motion through the air, flowing opposite to the flight path.
