Likely Test Questions

Question 1

Reference an aerofoil section Chordline. Dependant on whether the camber line runs above or below the chord line determines what?

Answer 1

Is the Aerofoil is positively, neutral or negative cambered aerofoil

Question 2

With reference to the lift formula Lift = CL1/2pV^2S, what two variables can the pilot change?

Answer 2

CL (angle of attack) and the EAS
To note - You may be able to change the wing surface area and angle of incidence using flaps. But its not the answer in the PowerPoint

Question 3

The aerodynamic force on an aircraft regardless of altitude is the?

Answer 3

Result of the IAS (or EAS)

Question 4

The difference between the IAS and the TAS is:

Answer 4

TAS is the IAS corrected for density error

Question 5

Total Pressure as Measured by the airspeed indicator is the comparison between

Answer 5

Dynamic and static pressure with static pressure

Question 6

Bernoullis principle is?

Answer 6

An ideal fluid has no internal friction and is incompressible
With an increase in Velocity, there will be a decrease in pressure to remain constant
High speed = low pressure / Low speed = High pressure
Due to this fact, Fast moving air over the surface of an aerofoil generates a low pressure bubble, slow moving air under the wing causes a high pressure bubble

Question 7

What is the total pressure that the Pitot tube is measuring?

Answer 7

Static and Dynamic
