Pitot-Static System Overview
The pitot system uses a composite fairing with an aluminum tube as pitot tube, connected via PVC hoses and
connectors to the dynamic pressure ports of both airspeed indicators and the GSU 25 ADHRS unit.
To drain water, a T-connector is installed at the lowest point of the system (in ground attitude) under the front
seat panel. The pitot line has a quick disconnect installed at the LH root rib, to simplify disassembly and
reassembly.
The static system features 2 static ports on the side of the fuselage, connected via PVC hoses and connectors
to the static pressure ports of the airspeed indicators, altimeters, altitude encoder and GSU 25 ADHRS.
The lines loop upwards from the static ports, preventing water intrusion.
To drain water from the system, the T-connector connecting both static ports can be opened.
To clean the lines, disconnect all ends of each line (instrument- and air data probe side), use compressed air to
remove fluids or other contamination. Inspect as required in accordance with section
5-06 item 19.
CAUTION: Never blow air through a line with an instrument connected,
this will cause serious damage to the instrument!
