The pitot system (ram air pressure) consists of one electrically heated pitot tube on
the left side of the nose, connected to the
airspeed indicator. The static system (ambient
air pressure) contains four electrically heated ports, two per side (upper and lower)
located immediately in front of each crew door.
The
upper right and lower left static ports provide primary equalized ambient pressure
to the airspeed and vertical speed indicators, and altimeter through the alternate static
source switch [PRI position]. The
lower right and upper left ports provide the switch
an alternate
ambient source [ALT position], and include provisions to connect to the
optional copilot instruments and optional wheel landing gears' auxiliary pitot-static
system (landing gear warning switch).
