CPL PoF Revision Basic Aerodynamic Theory

Dynamic Pressure

• Is caused by movement against a solid object

• Is caused when there is no movement of air

• Is static pressure²

• Only occurs when the aircraft moves backwards

½pV² relates to

• TAS

• EAS

• IAS

• CAS

Total (pitot) pressure is equal to:

• Static pressure - Dynamic pressure

• Dynamic pressure x Static pressure

• Dynamic pressure + static pressure

• Static pressure/dynamic pressure

TAS is EAS corrected for

• Pressure and density error

• Density and position error

• Density error

• Density and instrument error

Under ISA conditions IAS will be the same as

• EAS

• TAS

• CAS

• IAS²

If an aircraft climbs at a constant IAS:

• TAS will increase due to the increase in density

• TAS will decrease due to the decrease in density

• TAS will increase due to the decrease in density

• TAS will decrease due to the increase in density

Which of these aerofoils would be described as high speed

• B

• C

• A

The red line is

• The mean camber line

• The angle of attack

• The chord line

• The depth of the aerofoil

The angle of attack is the angle between the:

• Chord line and mean camber line

• Trailing edge and leading edge

• Chord line and relative airflow

• Angle of incidence and relative airflow

Angle of incidence is the :

• Angle between the chord line and lateral axis

• The angle the aerofoil is attached to the fuselage

• The angle of the fuselage compared to the main gear

• The angle between the main wing and the tail plane
