1. Pitot / Static System (See Figure 1.)
The pitot air system consists of a pitot mast located on underside of left wing, with its related plumbing.
Ram air pressure entering the pitot is transmitted from the pitot inlet through hose and tubing (routed
through the wing) to the airspeed indicator (and, if installed, to the Primary Flight Display (PFD) of the
Avidyne Entegra system) on the instrument panel. A partially or completely blocked pitot head will give
erratic or zero readings on the instruments.
The static air system consists of two static ports located on the left and right side of the aft fuselage.
The static ports are directly connected to the airspeed, altimeter and rate of climb indicators in the
instrument panel by means of hose and tubing. An alternate static air source is located below instrument
panel in front of pilot. Alternate static source is part of standard system and has a shutoff valve which
closes the port when it is not needed. A placard giving instructions for use is located on instrument
panel. Pitot and static lines can be drained through separate drain valves located on left lower side of
fuselage interior.
