Placard update
15.1 PITOT- STATIC SYSTEM
The pitot system conveys ram air pressure to the airspeed indicator. The static system
vents the vertical speed indicator, altimeter and airspeed indicator to atmospheric
pressure through plastic tubing connected to a static port. The pitot-static mast is located
on the underside of the starboard wing. The pitot-static system detects the total dynamic
pressure and the static pressure.
15.2 PITOT - STATIC WATER TRAPS
The pitot and static systems have not a water trap fitted, PVC tubes should be checked
when doing regular maintenance or after flying through rain. If water is ever found in the
PVC tubes it should be drained immediately. The draining procedure consists of removing
the PVC tubes from the instruments and dry them with compressed air.
15.3 PITOT - STATIC INSPECTION
The pitot-static mast is made from tubular aluminium. The pitot port is recognisable by the
large hole (usually similar in size of the tube). The static vent is recognisable by the small
hole that permits venting of atmospheric pressures.
Air pressure from the Pitot-Static mast is transmitted to the cockpit instruments via PVC
tubing. The dynamic pressure tube is coloured blue; the static pressure tube is coloured
white.
Pre flight inspection is required to ensure that no obvious blockages have ingressed into
the pitot-static head such as insects or dirt. The pitot-static mast should be secured to the
wing with no obvious signs of damage.
NOTE
: It is advisable to keep the pitot-static mast covered with the (pitot mast cover)
supplied with the aircraft whenever the aircraft is parked for prolonged periods.
