15.5 PITOT & STATIC SYSTEMS
15.5.1 DESCRIPTION
The pitot system conveys ram air pressure to the airspeed indicator.
The static system vents the vertical speed indicator (if fitted), altimeter and airspeed indicator to
atmospheric pressure through plastic tubing connected to a static port.
In Jabiru Aircraft the pitot and static systems each have a water trap
(or “low point”) fitted which must
be checked during scheduled maintenance or after flying through rain.
CAUTION
Proper maintenance of pitot and static system is essential for proper operation of the altimeter,
airspeed indicator and vertical speed indicator (if fitted). Leaks, moisture and obstructions in the
pitot system will result in false airspeed indications, while static system malfunctions will affect
readings of all three instruments. Cleanliness and security are the principal rules for system
maintenance. The pitot tube and static ports MUST be kept clean and unobstructed.
