2.18. PITOT – STATIC PRESSURE SYSTEM
The pitot-static tube is located under the leading edge of the right wing and consists of a air
duct. Total system pressure is sensed through the hole in the pitot-tube face and static pressure is
sensed through the holes on both sides of the rear part of fuselage.
Pressure distribution to individual instruments is received by means of flexible plastic hoses. The
tube supplies dynamic ram air pressure to the airspeed indicator, and the static ports supply
outside atmospheric pressure to the airspeed indicator, altimeter, and vertical speed indicator. If
installed, the altitude hold portion of the autopilot or mode C transponder is also connected to
the pitot system.
