NCAA CPL Principles of Flight Practice Questions - NCAA CPL Principles of Flight (Nigeria) Exam - NCAA CPL Principles of Flight Practice Questions - NCAA CPL Principles of Flight (Nigeria) Exam

Question 1

According to Bernoulli's principle, what occurs to static pressure and airflow velocity as air passes over the cambered upper surface of a subsonic airfoil?

Velocity increases and static pressure decreases Velocity decreases and static pressure increases Velocity increases and static pressure increases Velocity decreases and static pressure remains constant

Correct Answer:

Velocity increases and static pressure decreases

Question 2

How is the aerodynamic Angle of Attack (AOA) strictly defined?

The angle between the chord line of the airfoil and the relative wind direction The angle between the longitudinal axis of the aircraft and the horizon The angle between the chord line of the wing and the longitudinal axis of the fuselage The angle between the flight path vector and the horizontal ground plane

Correct Answer:

The angle between the chord line of the airfoil and the relative wind direction

Question 3

In fluid dynamics and aerodynamics, total pressure (stagnation pressure) is expressed by which fundamental formula?

Total Pressure = Static Pressure + Dynamic Pressure Total Pressure = Static Pressure - Dynamic Pressure Total Pressure = Dynamic Pressure / Static Pressure Total Pressure = Static Pressure × Density Ratio

Correct Answer:

Total Pressure = Static Pressure + Dynamic Pressure

Question 4

What is the primary operational distinction between a laminar boundary layer and a turbulent boundary layer over a wing?

A laminar boundary layer produces less skin friction drag but separates more easily than a turbulent boundary layer A laminar boundary layer produces higher skin friction drag and resists separation better than a turbulent boundary layer A turbulent boundary layer contains smooth parallel streamlines with zero mixing between fluid layers A laminar boundary layer is thicker and contains much higher kinetic energy near the wing surface

Correct Answer:

A laminar boundary layer produces less skin friction drag but separates more easily than a turbulent boundary layer

Question 5

What is the primary physical cause of induced drag on a fixed-wing aircraft?

The generation of aerodynamic lift and the resulting wingtip vortices and downwash Surface roughness and skin friction of the wing skin material The frontal area displacement of the aircraft fuselage and nacelles Shock wave formation behind the thickest point of the airfoil

Correct Answer:

The generation of aerodynamic lift and the resulting wingtip vortices and downwash
