b) Static pressure sensor:
See Figs. 76-46 and 76-47.
The location of the ambient pressure sensor (1) depends on
the aircraft type, but is limited by the length of the wiring
harness.
■
CAUTION: The sensor is designed for a pressure range of
100 hPa to 1200 hPa and the max. pressure
must not exceed 3500 hPa.
If the max. pressure is exceeded during the course of measur-
ing, the sensor must be replaced.
When taking the following readings the plug connection to the
wiring harness has to be disconnected and reestablished
immediately after completion of checks. The same applies for
the air pressure hose.
The easiest way to check function of the two pressure sensors
is by use of the communication program. If this program is not
at your disposal, the following static checks can be carried out.
-
Inspection for physical damage.
