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.
Astigmatism occurs when the normally spherically shaped lens of the eye is elongated in shape. The irregular form scatters the light that comes through the eye onto the retina, rather than focusing it on a single point. The result is fuzzy sight. Toric lenses are manufactured to properly bend the light so that it hits the retina on one spot. To provide consistently sharp vision, toric contact lenses need to stay relatively stationary on the eye. These special lenses have different zones of correction. Because of this unique construction, the lenses have to stay in place so that the areas of correction are hitting the right places.
