CAA NZ CPL Theory - Principles of Flight & Aircraft Performance Practice Questions - CAA NZ CPL Theory - Principles of Flight & Aircraft Performance (New Zealand) Exam - CAA NZ CPL Theory - Principles of Flight & Aircraft Performance Practice Questions - CAA NZ CPL Theory - Principles of Flight & Aircraft Performance (New Zealand) Exam

Question 1

According to the lift equation L = 0.5 * rho * V^2 * S * CL, what occurs to total lift if airspeed (V) is doubled while angle of attack and air density remain constant?

Total lift doubles (2 times initial lift) Total lift quadruples (4 times initial lift) Total lift increases by a factor of eight (8 times initial lift) Total lift remains unchanged due to drag compensation

Correct Answer:

Total lift quadruples (4 times initial lift)

Question 2

What is the fundamental cause of induced drag on a finite aircraft wing?

Air viscosity causing skin friction along the wing surface boundary layer Pressure differential between upper and lower wing surfaces generating wingtip vortices and downwash Form drag created by structural wing thickness interrupting airflow Shock wave formation as local airflow accelerates toward Mach 1.0

Correct Answer:

Pressure differential between upper and lower wing surfaces generating wingtip vortices and downwash

Question 3

What primary aerodynamic phenomenon occurs when an aircraft flies within one wingspan distance above the ground surface?

Induced drag decreases significantly due to reduction in upwash, downwash, and wingtip vortices Parasite drag increases due to compressed air underneath the wings Critical angle of attack decreases, causing an immediate stall at normal speeds Tailplane downforce increases, creating an extreme nose-up pitching moment

Correct Answer:

Induced drag decreases significantly due to reduction in upwash, downwash, and wingtip vortices

Question 4

Under what condition does an aerodynamic stall always occur?

When indicated airspeed drops below published power-off stall speed (Vs0) When the critical angle of attack is exceeded, regardless of airspeed, altitude, or pitch attitude When pitch attitude exceeds 20 degrees nose-up relative to the horizon When engine power is reduced to idle while in a climbing attitude

Correct Answer:

When the critical angle of attack is exceeded, regardless of airspeed, altitude, or pitch attitude

Question 5

What is the principal aerodynamic benefit of extending trailing-edge flaps during approach to landing?

Increases wing camber and max lift coefficient (CL max), allowing a lower landing speed and steeper descent path Decreases total drag while keeping lift constant to extend glide range Shifts the center of pressure rearward to decrease elevator control load Increases critical angle of attack to prevent premature stall

Correct Answer:

Increases wing camber and max lift coefficient (CL max), allowing a lower landing speed and steeper descent path
