Part B Section 12.36
12.36 PITOT STATIC SYSTEM
01 PITOT STATIC SYSTEM
The pitot head is a single, non-detachable unit. It's mounted with its axis parallel to the
thrust line of the aircraft, on the centre section leading edge of the Port wing.
The switch for the operation of the Pitot Heat is on the yoke. This switch should be off
whilst operating on the ground unless icing is suspected, and used only whilst airborne in
icing conditions.
Pitot-static tubes are designed to operate satisfactorily under all operating conditions,
including those in which rain and ice are encountered. Snow and ice are melted by the
heating element and the resulting water is prevented from entering the connecting tubing
by drain traps in the Nose. An accessible drain plug incorporated in the lowest point of
each system of connecting tubing removes water. These plugs are located beneath the
port side of the instrument panel.
An Alternate Static source is available in the flight station, switched from the far right side
of the instrument panel.
02 DE-ICING EQUIPMENT
All of the de-icing gear has been removed from the aircraft, including the heat exchange
mechanism for de-icing the wings and tail.
The anti icing systems remaining are the electrically operated Carburetor Heat and Pitot
Heat, both switched from the Yoke.
