The term is rotate. It is the point when the aircraft is at a speed that it can safely lift off and the pilot rotates the control column aft to make the plane climb. Source(s): Former USAF Aircrew.
Crazing is the phenomenon that produces a network of fine cracks on the surface of a material, for example in a glaze layer. Crazing frequently precedes fracture in some glassy thermoplastic polymers.razing occurs in some thermoplastics such as acrylonitrile butadiene styrene (ABS plastic) when stressed. It is a typical response in rubber toughening, where crazes are initiated at the surfaces of the rubber particles added to toughen the material.
The probe cross section can be distorted to form an ellipse, due to a range of factors such as level of machining accuracy and the material of the pole-piece, imperfections in the casting of the iron magnets and the copper winding. This distortion is called astigmatism and causes focus difficulties. Bad or gross astigmatism can be seen as streaking in the image in an X direction that changes to the Y direction as the image passes through focus from under focus to over focus.
