34. NAVIGATION AND PITOT STATIC
34.00.00 General
This chapter provides information on those systems that provide the aircraft navigational data such as
the Pitot static system, Airspeed indicator, altimeter, outside air temperature gauge.
34.10.00 Flight Environment Data/Pitot Static
The Pitot Static system for the aircraft has a single entrance at the extreme front of the pod. A single
6mm ID tube travels rearward to a tee intersection. From the splitter a 6mm ID tube continues to the
pilots left and to the analogue air speed indicator. A second 3mm tube splits to the pilots right and into
the SkyDAT readout. The tubes are both made of PVC and may be replaced if necessary. The length of
the tubing is important in order to ensure that any moisture that may be in the tubes will tend to drain
out of the front of the Pitot tubes. The other function of the length of the tubes is to ensure that there is
less possibility of kinking the tubing. Interference fits are used to keep the tubing in place and some
stretching may be required to get new 3mm ID tubing onto the tee intersection fitting.
34.10.10 Maintenance Practices
Figure 37 Dynamic Port (Pitot Entry)
Check that the Pitot port is free from obstruction, or insect nests. The lines may be visually checked
from the inside of the Pod for obstructions as the tubing is clear.
