7.12. PITOT AND STATIC PRESSURE SYSTEMS
The pitot pressure is measured on the leading edge of a calibrated probe below the left wing. The static
pressure is measured by the same probe using two holes in the lower edge and rear edge of the probe.
For protection against water and humidity, water sumps are installed within the line. These water sumps
are accessible beneath the left seat shell.
The error of the static pressure system is small enough to be neglected for the measuring of the altitude.
For the error of the airspeed indicating system refer to Chapter 5.
The pitot static pressure probe should be protected whenever the aircraft is parked to prevent
contamination and subsequent malfunction of the aircraft systems relying on its proper functioning.
NOTE
Use only the factory supplied pitot static probe cover, P/N G-659-200 with the “Remove
before Flight” flag attached.
7.13. STALL WARNING SYSTEM
When the airspeed drops below 1.1 times the stall speed, a horn sounds in the left instrument panel. The
horn grows louder as the speed approaches the stall speed. The horn is activated by suction on a hose
that leads from a hole in the leading edge of the left wing to the horn. The hole is marked by a red circle.
The stall warning hole should be plugged whenever the aircraft is parked to prevent contamination and
subsequent malfunction of the stall warning system.
NOTE
Use only the factory supplied stall warning plug, P/N 20-1010-01-00 with the “Remove
before Flight” flag attached.
7.14. AVIONICS
The center of the instrument panel contains the radio and navigation equipment. The microphone key for
the radio is installed in the control stick. There are two connectors for headsets on the backrest of the
seat.
Operating instructions for individual avionics equipment should be taken from the manuals of the
respective manufacturers.
