1. A system for detecting accumulation of ice on a surface of an aircraft, comprising:

  • air pump means for pumping air;

    a first generally horizontal extending exterior surface of an aircraft, said first surface being on an upper side of said aircraft and exposed to precipitation falling from above;

    at least one first opening in said first horizontally extending surface;

    a second surface of said aircraft, said second surface not exposed to precipitation;

    at least one second opening in said second surface;

    first conducting means for conducting air from said air pump means to said first opening;

    second conducting means for conducting air from said air pump means to said second opening;

    differential pressure sensing means for sensing a difference in pressure between said first and second conducting means; and

    indicating means in connection with said sensing means for indicting said pressure difference to an operator of said aircraft.
