What: Qantas Boeing 737-800 en route from Sydney to Brisbane
When: Jul 26th 20
Why: While en route, the anti-icing system of the 737 failed. The flight diverted to Sydney and made a safe landing–after having experienced the same problem on the 25th.
It would be interesting to know the details of the system failure. Around this time last year, Air France Flight 447 went down in mysterious circumstances; it is speculated that the pitot tubes froze over, and that the fly by wire Airbus (unlike this Qantas Boeing) was rendered uncontrolled.
So if this was a frozen pitot tube situation where the pilots were able to make a safe landing in a Boeing, one wonders if aspects of Airbus fly by wire should be re-considered.
But this is food for thought only, as I do not have the exact details of the anti-ice system failure.
