ABSTRACT OF THE DISCLOSURE A short multiple static pressure sensing probe that is compensated for both subsonic and supersonic speeds in the same probe and a family of such probes for different aircraft with each of the probes in the family having a common barrel configuration except for the final shaping of compensation surfaces and the location of static pressure sensing ports . In an assembly operation, heaters and interconnecting wires, bulkheads and pressure tubing are arranged, internal to the probe, to be clear of predetermined areas in which static pressure ports may be located. In a finishing operation, compensation surfaces are produced and static pressure ports are created at selected locations in the predetermined areas, thus avoiding damage to internal parts. A preferred arrangement of compensation surfaces facilitates multiple subsonic and supersonic compensation by providing at least two regions of relatively constant, but selectable, supersonic compensation pressures that coincide along the length of the barrel with two regions of variable subsonic pressures. The supersonic compensation in this preferred arrangement is adjusted to the desired levels by selecting two of the compensation surfaces . The subsonic compensation is then adjusted by selecting a second two of the compensation surfaces and the location of the static presssure ports .
