PL080 - Principles of Flight PPL(A)

With increasing angle of incidence of the wings: 

With increasing bank angle in coordinated turn G-force: 

The cause of buffeting is: 

Increase of lift force on the elevator caused by the movement of yoke or stick is: 

The point on aerofoil, which is locatede the most aft to the direction of flight is:

The point on aerofoil, which is located the most forward to the direction of flight is:

The point, where the line of resultant aerodynamic force intersects the chord line is:

Point with respect to which the aerodynamic moment does not depend on the angle of attack (in a large range of changes of the angle of attack) is:

 The difference of increase of drag forces resulting from the aileron deflection by the same angle but in opposite directions gives:

Differential aileron deflection is used to:

The movement of the aircraft during flight is described by:

Drag force of the wing moving down in the spin entry phase is:

The force generated by the pressure difference before and after the body flowed by the air is:

Aerodynamic forces depend on the air density. How do they change when the density decreases? 

Slats are used to:

Vertical stabilizer is primarily responsible for stability:

Horizontal stabilizer is primarily responsible for following stability: 

Dynamic lateral stability concerns:

Longitudinal dynamic stability concerns: 

Dutch roll concerns:

Static directional stability concerns:

Static longitudinal stability concerns:

Static Lateral Stability of concerns: 

The ratio of the distance traveled in that time is:

The ratio of the surface of the wing span is: 

Change of the velocity at time t to time t is:

Maximum Thickness:

The Mean Camber Line:

The average angular acceleration in a rotating movement is:

The aerodynamic center is the point:

The aerodynamic center wiith the increase of angle of attack:

Center of Pressure (CP) is a point: 

Change suppression of flight parameters has an affect: 

Buffeting of the tail surfaces is otherwise known as: 

The negative slant of wing causes:

Tail of the direction designed to rotate the airframe towards: 

Tail height designed to rotate the airframe towards: 

To eliminate of the aileron torque resistance as principle we use: 

In everyday life we meet the state of stability: 

In which conditions, the density altitude is equal to the standard altitude accordirng to ISA ?
