FAA Sport Pilot Airplane (SPA)

C. 2 hours 0 minutes

Time en route = Distance ÷ Groundspeed = 180 NM ÷ 90 knots = 2.0 hours. Since the headwind reduces the groundspeed to 90 knots (not the 105-knot true airspeed), the correct groundspeed must be used for the time calculation, giving exactly 2 hours 0 minutes.

B. A squall line

A squall line is a narrow, non-frontal band of active thunderstorms that often forms ahead of a fast-moving cold front and can produce severe turbulence, hail, and damaging winds, sometimes more severe than the front itself.

A. 28 minutes

Distance covered in 30 minutes = 165 − 80 = 85 NM, giving a groundspeed of 85 NM ÷ 0.5 hr = 170 knots. Time for remaining 80 NM = 80/170 hr = 0.4706 hr ≈ 28 minutes.

B. Get-there-itis

'Get-there-itis' describes a pilot's fixation on reaching the destination as planned, often leading to poor risk decisions such as departing into marginal weather. It is a form of self-induced pressure rather than pressure imposed by others.

A. 'Cessna 456CD, cleared into the Class Bravo airspace'

14 CFR 91.131 requires that an aircraft receive an explicit ATC clearance before entering Class B airspace. Only a specific statement authorizing entry, such as 'cleared into the Class Bravo airspace' or 'cleared to enter the Class Bravo,' satisfies this requirement; radar contact and squawk code assignment alone do not.

B. higher than actual altitude

Cabin air pressure is typically lower than outside static pressure due to airflow effects, so feeding this lower pressure to the altimeter causes it to interpret the lower pressure as a higher altitude. The airplane will therefore fly slightly lower than the altimeter indicates.

D. 2°C

The standard lapse rate is 2°C (3.5°F) per 1,000 feet of altitude increase, used as the baseline for density altitude and performance calculations.

C. 1,320 pounds

14 CFR 1.1 defines a light-sport aircraft (other than a seaplane) as having a maximum gross takeoff weight of 1,320 pounds. Seaplanes are allowed a higher weight of 1,430 pounds due to the added weight of floats.

B. The leans

The leans occur when a pilot fails to perceive a bank or its correction due to a slow, gradual entry, causing a false sensation that the aircraft is still turning when it is actually level, prompting an incorrect corrective bank.

B. An authorized flight instructor, certifying the applicant received the required ground training or completed a home-study course and is prepared for the test

14 CFR 61.35(a)(1) requires that an applicant for a knowledge test present, as applicable, an endorsement from an authorized instructor certifying that the applicant has received the required ground instruction or has completed an appropriate home-study course and is prepared for the knowledge test.

A. The pilot must become familiar with all available information concerning the flight, including NOTAMs and TFRs

14 CFR 91.103 requires every pilot in command to become familiar with all available information concerning that flight, which includes checking NOTAMs and TFRs regardless of whether the flight is IFR or VFR, or the distance flown.

D. available weather reports and forecasts, and alternatives available if the flight cannot be completed as planned

14 CFR 91.103 requires each pilot in command, before beginning a flight, to become familiar with all available information concerning that flight, including weather reports/forecasts and alternatives available if the flight cannot be completed as planned, for flights not in the vicinity of an airport.

C. 1 statute mile visibility and clear of clouds

In Class G airspace at or below 1,200 feet AGL during the day, 14 CFR 91.155 requires only 1 statute mile visibility and remaining clear of clouds. The stricter 3 SM/152 cloud clearance rules apply above 1,200 feet AGL or at night.

A. 71 knots

A 60° bank turn produces a load factor of 2 G. Stall speed increases by the square root of the load factor: new stall speed = 50 × √2 = 50 × 1.41 ≈ 71 knots.

C. VX, best angle of climb speed

VX (best angle of climb speed) gains the most altitude for a given horizontal distance traveled, making it ideal for clearing obstacles close to the runway. VY gains altitude fastest per unit time but covers more ground distance.

B. Somatogravic illusion

The somatogravic illusion occurs when rapid linear acceleration, such as during takeoff, is misinterpreted by the vestibular system as a nose-up pitch attitude, prompting the pilot to push the nose down dangerously close to the ground. Trusting flight instruments rather than bodily sensations prevents this hazard.

C. A line of thunderstorms affecting at least 40% of a 3,000-square-mile area, or thunderstorms with heavy precipitation

A Convective SIGMET is issued for a line of thunderstorms, thunderstorms affecting 40% or more of a 3,000-square-mile area, embedded thunderstorms, or any severe/hail-producing thunderstorm. It also implies possible severe/extreme turbulence, wind shear, and hail.

D. The airport has an operating control tower

On sectional charts, airport symbols are printed in blue if the airport has an operating control tower, and in magenta if it does not. This color coding helps pilots quickly identify whether they need to establish two-way radio communication before entering the airport's traffic pattern or associated airspace.

B. Single-Pilot Resource Management (SRM)

Single-Pilot Resource Management (SRM) is the ability to effectively gather information and use all available resources — human, hardware, and information — to safely conduct a flight when operating alone. Using weather briefings, NOTAMs, an instructor's advice, and performance data all reflect the effective use of information resources under SRM.

C. Service ceiling

Service ceiling is defined as the altitude at which the airplane's maximum rate of climb decreases to 100 feet per minute. Absolute ceiling is the altitude at which climb rate reaches zero.

D. NOTAMs provide information such as runway closures, taxiway restrictions, and out-of-service navigation aids

NOTAMs (Notices to Air Missions) contain time-critical information such as runway/taxiway closures, obstructions, and navigation aid outages that are not yet published in aeronautical charts. 14 CFR 91.103 requires pilots to become familiar with all available information, which includes NOTAMs for the intended flight.

D. An isogonic line connecting points of equal magnetic variation, used to convert between true and magnetic courses

An isogonic line is a dashed line on aeronautical charts connecting points of equal magnetic variation. The labeled value (e.g., 10°E) tells the pilot how many degrees to add or subtract when converting a true course to a magnetic course in that area.

C. lower than indicated altitude

In colder-than-standard air, air is denser, so pressure levels are compressed closer together than standard, causing the airplane to actually be lower than the altimeter indicates. This is summarized by the memory aid 'from hot to cold or high to low, look out below,' warning pilots that true altitude may be lower than indicated in cold temperatures, especially critical near mountainous terrain.

C. Intake, Compression, Power, Exhaust

The four-stroke cycle occurs in this order: intake (fuel/air mixture drawn in), compression (mixture compressed), power (ignition drives piston down), and exhaust (burned gases expelled).

D. A strong, potentially damaging downdraft or microburst caused by evaporative cooling of the falling precipitation

Virga is precipitation that evaporates before reaching the ground; the evaporative cooling process can create a strong downdraft, sometimes leading to a dry microburst even in the absence of visible surface rain or a mature thunderstorm.
