AF Flight 447: NTSB Investigating Two Recent Incidents Involving Pitots
LuckyBogey's Blog ^ | June 26, 2009 | LuckyBogey

In the interest of caution, the NTSB advisory appeared earlier yesterday evening in my RSS feed however the advisory was not published on the NTSB website until this morning and I wanted to wait until official confirmation. As Eurocockpit says:

“This initiative of the NTSB is more than welcome: almost a month after an accident for which no one can say that the probes did not play a major role, no airworthiness directive (AD) has been issued (yet?) by Europe.

If the NTSB was to “discover” an anomaly in the AA type probes, the U.S. Administration of Civil Aviation (FAA) could launch an Airworthiness Directive for A330 and A340. It would be a historic premiere.”

The BEA “le circus” in Paris is getting very old. Why not simply tell the truth, provide the public the facts. That is all we ask…

...The National Transportation Safety Board is investigating two recent incidents in which airspeed and altitude indications in the cockpits of Airbus A-330 aircraft may have malfunctioned.

The first incident occurred May 21, 2009, when TAM Airlines flight 8091 flying from Miami, Florida to Sao Paulo, Brazil, experienced a loss of primary speed and altitude information while in cruise flight...

... The Safety Board has become aware of another possibly similar incident that occurred on June 23 on a Northwest Airlines A-330 flying between Hong Kong and Tokyo...

...Ground the Airbus? Airbus composite stabilizers, rudders and couplers have also been involved in a number of other emergency in-flight incidents that did not lead to crashes, injuries or deaths.

There is now a question whether all Airbus aircraft equipped with composite stabilizers and rudders should be grounded until the cause of the crash of Flight 447 can be identified...

What, you think pitot is another word for pilot? A pitot is a tube that is large at one end, then narrows to a smaller diameter, and enlarges again. The constriction causes the velocity of air to increase as a greater volume of air is forced through a smaller opening. Pitots are used in airspeed indicators and in carburetors.

If I may, I think you have defined a venturi, not a pitot.

I pitot measures dirrefential air pressures, not so much flowing air speed per se.

See this diagram as an example
