Pneumatic system
The aircraft pneumatic system consists of:
• Static (P
STAT
) piping for the ASI and altimeter
• Dynamic (P
TOT
) piping for the ASI
• Static piping for the variometer from fin probe
• Total energy (TE) piping from the fin probe
The pneumatic piping is colour coded as follows:

Table 7.5-1
Figure 7.5-2 gives a schematic of the instrument layout.
NOTE: The ASI must use the static sources located in the rear
of the fuselage tube. The airspeed calibration values are
based on these static port readings.
NOTE: Static ports located in the rear of the fuselage tube are
marked with a red ring and must be kept unobstructed
to ensure correct ASI readings.
