Gun effective ceiling varied depending on the predictor and fuze. The Mk VI ordnance significantly increased the potential effective ceiling. The British definition of effective ceiling at the start of World War II was “that height at which a directly approaching target at 400 mph can be engaged for 20 seconds before the gun reaches 70° elevation”

Famous quotes containing the word performance:

    So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.
    Melinda M. Marshall (20th century)

    To vote is like the payment of a debt—a duty never to be neglected, if its performance is possible.
    Rutherford Birchard Hayes (1822–1893)

    The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.
    Viola Spolin (b. 1911)
