34-10-00 FLIGHT ENVIRONMENT DATA
This Section describes that portion of the system which
senses the environmental conditions and uses the data to
influence navigation.
34-10-01 Pitot/Static System
The pitot/static tube is designed to pick up pitot pressure and
static pressure. It is screwed through the L.H. outboard
leading edge into an attachment block located at the rear web
of the main spar. From there the pressures are transmitted by
means of a vinyl tube which is routed through an aluminium
tube inside the wing to the left side of the fuselage and
further to the instrument panels. The ends of each vinyl tube
are marked with the letters "P" or "S" for pitot resp. static
pressure line. The pitot/static system can be drained by
means of an U-shaped drain which is located at the left side
of the cockpit as shown in figure 1.
