Lecture #1 09/18/11 ASE167M – Apurva Chunodkar 5 Pitot-Static Systems Essential requirements in the measurement of a/c performance are The state of the atmosphere The relative motion between the aircraft and the air mass Of the primary flight instruments (altimeter, airspeed, VVI, HSI, compass, turn coordinator), the first three use the Pitot-static system The Pitot-static systems drive instruments (mechanical movement of a pointer) that use the difference between the static and total pressure, or just static pressure (independent of electrical power supply) System includes a Pitot tube for measuring impact (ram) pressure, and static ports for measuring barometric static pressure.

Lecture #1 09/18/11 ASE167M – Apurva Chunodkar 6 Pitot-Static Systems Feb. 6 th , 1996 – Birgenair Flight 301 crashes shortly after takeoff due to the Pitot tube being blocked and thus causing the system to provide incorrect airspeed data. October 2 nd , 1996 – AeroPeru Flight 603 crashes because of blockage of the static ports. The static ports on the left side of the aircraft had been taped over while the aircraft was being waxed and cleaned. After the job was done, the tape was not removed.
