Chinese COMAC ARJ21-700 Certification Testing Continues

This most recent series of tests, involving water ingestion during high speed ground operations, is neither particularly complicated nor dangerous as compared to high AOA or flutter, for example.  But the test is not easy to set up, and the plane still has to pass.  The engine manufacturer is typically the one swetting bullets.  The good news is that often doing something as simple as going to a different nose wheel tire can make a big improvement in how the plane performs.  No report on how this one went, but that sure looks like a lot of water going down the intakes to me.
