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.
3,084. Ground lenses are more prone to crazing, due to slight changes in the substrate caused by uneven tool pressure. Heat is the primary cause, substrate changes are the second most common cause of crazing I see. Crizal is more prone to heat damage than other AR's.egassing is when the water is taken out of the lens through heat before the coating process. If any moisture remains, it could be detrimental later. If the lens is warmed with trapped moisture it can cause crazing months or years down the road.
