PROBLEM TO BE SOLVED: To provide systems and methods for de-icing an inlet screen and dehumidifying an inlet air filter in a gas turbine engine.SOLUTION: A method may include determining a current inlet screen temperature. The method also may include determining a desired inlet screen temperature. If the current inlet screen temperature is less than the desired inlet screen temperature, the method may further include determining a first amount of gas turbine compartment 120 ventilation discharge air necessary to achieve the desired inlet screen temperature, extracting the first amount of gas turbine compartment ventilation discharge air, and conveying the first amount of gas turbine compartment ventilation discharge air to the inlet screen 112.
