PITOT-STATIC SYSTEM – MAINTENANCE PRACTICES
3. PITOT STATIC SYSTEM – DRAINAGE
For the static system, ports are located on the lowest part of the system and drainage
occurs through the ports themselves, so that water/moisture will drain towards the
exterior of the aircraft, or through the alternate port.
The dynamic system does not have a natural drainage path but it is fitted with a
parallel path with a dedicated filter which allows catching the moisture present in the
air, in order not to affect the instruments.
The following steps describe the procedure to check for dirt and replace, if necessary,
the mentioned filter (water trap).
