The Preston PS-525 Pitot-Static Test Set is used to check for leaks in the pitot-static and AOA
systems. Other equivalent pitot-static test instruments may also be used, and the procedures for them
should be similar. When using a different test set, use these procedures as guide for test methodology
while referring to the manufacturer’s instructions.
It is acceptable to create connections using alternate means than shown in these procedures so long
as they are confirmed to be leak free.
It is preferable that a calibrated test set be used, but if not readily available, the pitot-static system can
be tested with simple tools such as a syringe. (See “Pitot Static Leak Check Operation” on page 13-75.)
