EASA ATPL 081 Principles of Flight Practice Questions - EASA ATPL Theory - Principles of Flight (081) Exam - EASA ATPL 081 Principles of Flight Practice Questions - EASA ATPL Theory

Question 1

Applying the continuity equation to incompressible, subsonic flow through a streamtube, what happens to the flow velocity as the cross-sectional area of the tube decreases?

The velocity decreases The velocity remains constant The velocity increases The density increases proportionally

Correct Answer:

The velocity increases

Question 2

According to Bernoulli's theorem for incompressible flow, if the static pressure in a streamtube decreases, what must happen to the dynamic pressure, assuming total pressure remains constant?

Dynamic pressure decreases Dynamic pressure increases Dynamic pressure stays the same Total temperature increases

Correct Answer:

Dynamic pressure increases

Question 3

Dynamic pressure (q) is calculated using which expression, where rho is air density and V is true airspeed?

rho x V 1/2 x rho^2 x V rho x V^2 1/2 x rho x V^2

Correct Answer:

1/2 x rho x V^2

Question 4

On a conventional cambered aerofoil at a small positive angle of attack, the chordwise point of lowest static pressure (suction peak) is normally located:

At the trailing edge Near the leading edge on the upper surface At the centre of pressure On the lower surface near mid-chord

Correct Answer:

Near the leading edge on the upper surface

Question 5

What is the definition of the chord line of an aerofoil section?

The line equidistant from the upper and lower surfaces The straight line joining the leading edge to the trailing edge The line of maximum thickness The mean line of the camber distribution

Correct Answer:

The straight line joining the leading edge to the trailing edge
