self test for pitot static system?

A LH Cargo 772 recently took off with the two main static port lines not connected after maintenance. Clogged, capped or frozen Pitot tubes have caused air plain crashes.

Is there no self testing system commercially available or has been proposed that would detect major leaks, unconnected lines or closed ports to the outside world?

That’s pretty sad. Some engineers signed off the work as completed, when it obviously was not. Could have cost lives, as it was it did cost the price of all that fuel they dumped.

B2 should have carried out a complete test with a test set. If the system was incomplete, it would have showed a massive fail. The stamper should be prosucuted in a legal court if they signed it off. Too many gash people with stamps. Actually both stampers should be done as they stamped and never checked.

Yes, all that has been discussed ad nauseam in the Rumours & News forum. Does anyone know if a self test has been proposed or commercialised?

A pitot static system is a physcial thing. It needs an external test device to prove it. That needs a competent person to do the test. I would never operate a Drunk test set without the training. B1.1 . Not passed the levels of knowledge to be proved as competent.
