What is ROLL?

Aerobatic manoeuvre consisting of a complete revolution about the longitudinal axis. In a slow roll the centre line of the aircraft follows closely along a horizontal straight line; an uyward roll is similar, but considerable height is gained; a hesitation roll is one where the pilot brings his aircraft momentarily to rest in its rolling motion. A vertical upward or downward roll is usually called an aileron turn because these are the only control surfaces involved. A flick roll is an entirely different, very rapid and violent manoeuvre in which the aircraft makes its revolution along a helical path; high structural stresses are imposed and many countries ban this aerobatic. A half-roll is lateral rotation through 180'.
