A pressure sensing system strategically located measures static pressure of the inlet air of a gas turbine engine that is utilized as a signal indicative of engine inlet total pressure. The system consists of a number of ports circumferentially spaced around the engine case near the face of the engine which communicate with a manifold for feeding the average static pressure to a transducer.

For a gas turbine engine having a casing defining an inlet for leading air to said engine, a plane transverse to said inlet defining the upstream end of said engine, means for measuring the static pressure for obtaining a value of the total pressure of the airstream in said inlet that exhibits a value within a tolerance that is acceptable to be used in an engine control, said means including a plurality of ports circumferentially spaced in said casing located in proximity to said face for leading static pressure into a common manifold, and means for measuring the pneumatic pressure in said manifold for obtaining an average value of the static pressure of the air being admitted into said engine.
