– Static System Test (all J-Series)
11.6 Alternate Static Source (all J-Series)
11.6.1 Description
Jabiru Aircraft may be equipped with an alternate static source. This system is for Night-VFR aircraft
so that, should the primary static source become blocked, the pilot may switch to an alternate supply.
In the Jabiru this system consists of a section of the static tube which is exposed at the underside of
the instrument at a position where the pilot can reach it in flight. Where a problem is detected the
pilot reaches down and pulls on the tube, disconnecting it from the static probe in the tail. The
aircraft instruments will now take cabin pressure as static pressure, which will be a very close
approximation to the outside atmospheric pressure.
