Aircraft pressure measurement device including an enhanced cleaning system

A pressure measurement device for use on an aircraft, the pressure measurement device comprising:

• a pressure sensor positioned within the aircraft;
• a pressure measurement path extending between the pressure sensor and an air inlet situated at a skin of the aircraft, wherein the pressure measurement path allows air to flow from outside the skin of the aircraft to the pressure sensor;
• a valve fluidly coupled to the pressure measurement path between the skin of the aircraft and the pressure sensor;
• and
• a fluid port configured to supply a clearing fluid, and selectively fluidly coupled to the pressure measurement path via the valve,
• wherein the valve is actuatable between at least two states:
• a closed state wherein the fluid port is fluidly isolated from the pressure measurement path, and an open state wherein the fluid port is fluidly connected to the pressure measurement path.
