Role (aerobatics)
Role referred aerobatic several maneuvers , in which a plane at 360 degrees to rotate about the longitudinal axis . The flight direction and altitude are roughly maintained in level flight. One differentiates:
- Steered roller : The aircraft is steered by the roller with normal rudder action.
- Torn role : an auto-rotation is triggered by a deliberately induced one-sided stall.
- Barrel roll : A combination of controlled roll and simultaneous looping. The plane flies the surface of a lying imaginary cylinder.
Analog movement in biology
- When diving, a person can swim a role in any direction.
- Bats land to hang from a ceiling using a half roll by folding a wing.
