Which force directly counteracts the weight of an aircraft in steady, level flight?
Lift
Momentum
Thrust
Drag
In steady, level flight the lift generated by the wings equals the aircraft's weight. Lift acts perpendicular to the relative wind and counterbalances gravity.
According to Bernoulli's principle, what happens to air pressure as the speed of airflow over a wing increases?
Pressure decreases
Temperature decreases
Density increases
Pressure increases
Bernoulli's principle states that an increase in fluid speed leads to a decrease in pressure. This pressure drop over the wing's upper surface contributes to lift generation.
What condition characterizes an aerodynamic stall in an aircraft wing?
Angle of attack exceeds the critical angle
Weight exceeds maximum takeoff mass
True airspeed drops below TAS
Flaps extended beyond maximum limit
A stall occurs when the angle of attack surpasses the wing's critical angle, causing airflow separation and a sudden loss of lift. Airspeed alone does not define stall without reference to angle of attack.
When encountering a left crosswind en route, which pilot adjustment helps maintain the intended ground track?
Reduce airspeed
Climb to avoid drift
Apply a crab angle into the wind
Increase thrust
Crabbing into the wind by pointing the aircraft nose into the wind counteracts lateral drift. This keeps the ground track aligned with the planned course.
Which radiotelephony call indicates an urgent situation requiring assistance but not immediate danger to life?
Pan-Pan
Roger
Mayday
Securité
"Pan-Pan" signals an urgent situation that needs assistance but is not an immediate threat to life or the aircraft. "Mayday" is reserved for distress emergencies.
What does magnetic variation refer to on aeronautical charts?
Change in aircraft heading caused by electrical fields
Angular difference between true north and magnetic north
Difference between geographic north and grid north
Variation in true airspeed due to magnetism
Magnetic variation is the angular difference between true north and magnetic north at a given location. Pilots apply it to convert between true and magnetic headings.
Which type of route provides the shortest distance between two distant airports on a global chart?
Mercator line
Rhumb line
Great circle route
Isogonal line
A great circle route is the shortest path between two points on the Earth's surface. On a Mercator chart it appears curved compared to a straight rhumb line.
If a flight leg is 120 nautical miles and the true airspeed is 120 knots with no wind, what is the time en route?
30 minutes
2 hours
1 hour 30 minutes
1 hour
Time en route is calculated by dividing distance by speed: 120 NM ÷ 120 kt = 1 hour. This basic nav calculation helps in fuel planning.
Which frontal system is most commonly associated with cumulonimbus clouds and severe turbulence?
Occluded front
Stationary front
Cold front
Warm front
Cold fronts force warm air to rise rapidly, producing cumulonimbus clouds and turbulence. Warm fronts usually produce stratiform clouds with gentler lift.
In which atmospheric layer does most weather phenomena affecting VFR operations occur?
Troposphere
Thermosphere
Stratosphere
Mesosphere
The troposphere contains nearly all weather systems and cloud formations up to about 36,000 feet at the equator. Above it, conditions are generally stable.
Prior to entering Class D airspace, what must a pilot ensure?
Two-way radio communication is established
IFR flight plan filed
ATC clearance in writing
Transponder code assigned
Class D entry requires established two-way radio communications with ATC. A transponder or IFR plan is not automatically required unless specified.
Which instrument component indicates slip or skid during a turn?
Pointer in the vertical speed indicator
Rotor in the attitude indicator
Ball in the inclinometer
Gyro in the turn coordinator
The inclinometer's ball shows lateral acceleration; its position in the curved tube tells the pilot if the aircraft is slipping or skidding. Coordinated turns center the ball.
How does high density altitude affect aircraft takeoff performance?
Improves climb rate
Decreases takeoff distance
Increases takeoff distance
Has no effect
Higher density altitude means thinner air, reducing engine thrust and wing lift. Pilots need longer takeoff rolls and will experience reduced climb performance.
Which radiotelephony response indicates receipt and understanding but not necessarily compliance?
Over
Roger
Wilco
Affirmative
"Roger" confirms that the pilot has received and understood the transmission. "Wilco" combines that understanding with compliance to the instruction.
What is the standard rate of turn in instrument flying?
10 degrees per second
2 degrees per second
5 degrees per second
3 degrees per second
A standard rate turn of 3° per second completes a full 360° turn in two minutes. This rate is fundamental for IFR procedures.
An aircraft has two weights: 800 lb at an arm of 35 in and 1,200 lb at an arm of 75 in. What is the center of gravity arm in inches?
59 inches
65 inches
72 inches
50 inches
Total moment = (800à - 35)+(1200à - 75)=118,000. Total weight =2,000 lb. CG arm =118,000÷2,000=59 in.
At a pressure altitude of 5,000 ft and an OAT of 30 °C, what is the approximate density altitude?
6,500 ft
8,000 ft
9,200 ft
10,000 ft
ISA at 5,000 ft is - 5 °C, so deviation is +35 °C. DA ≈ PA +120à - ISA dev =5,000+120à - 35≈9,200 ft.
Given a true course of 090°, TAS 120 kt, and wind from 360° at 30 kt, what approximate heading and groundspeed will maintain the course?
Heading 104°, groundspeed 116 kt
Heading 090°, groundspeed 120 kt
Heading 076°, groundspeed 116 kt
Heading 076°, groundspeed 88 kt
Wind from 360° is a left crosswind, requiring a 14.5° crab into wind: 90 - 14.5≈76°. Groundspeed =120à - cos 14.5°≈116 kt.
Which ATC instruction requires a mandatory pilot readback to confirm correct receipt?
Runway-in-use
Altitude assignments
Updated QNH information
Reported traffic advisories
Regulations require readback of all altitude (and heading) assignments to ensure clearances are correctly understood. Other items are informational.
Under VFR regulations, what minimum fuel reserve is required for night flights?
45 minutes
15 minutes
30 minutes
60 minutes
Night VFR regulations mandate a reserve of at least 45 minutes of fuel after reaching the first point of intended landing. Day VFR reserve is 30 minutes.
