Question 1

Dynamic Rollover

Answer 1

Susceptibility to a lateral rolling tendency that requires three conditions

Pivot point
rolling motion
exceeding the critical angle

Question 2

This symmetry of lift

Answer 2

Difference in lift between the advancing and retreating halves of the rotor disc

Question 3

Translating tendency

Answer 3

Tendency of a hovering helicopter with a single counterclockwise rotating main motor blade to drift to the right

Question 4

Transverse flow

Answer 4

Right full of the aircraft between 10 and 20 knots
