Brazil - Ice damage to speed sensors made by Thales SA may have prompted incorrect readings on the Air France plane that crashed on June 1, contributing to the Airbus A330’s plunge into the Atlantic Ocean, which killed 228 people.

Investigators will ask Thales to supply information because damage to the three external sensors is a possible cause of “incoherent” speed data transmitted by the airliner, said a person familiar with the investigation who asked not to be named because the proceedings are confidential.

Honeywell International Inc., whose components aboard the crashed plane included processors that interpret the data and feed it to the main flight computer, said it has been asked to help with the probe. Thales, based in Neuilly-sur-Seine, France, said it will assist if called upon.

If I understand correctly, they are refering to the petot heads, the inlet that takes in air to sense altitude and airspeed. That is an ancient system. Although all airplanes are still equipped with this, they all have GPS. So, my question is how does a broken sensor on the wing leave the pilot clueless? Unless perhaps, they are talking about the GPS antenna.

Halevi, you appear to be very knowledgeable. Which sensors feed the flight computer?

They are talking about the gasket and the alternator with the relay and contactor. Like you now anything about planes you sound like my mechanic freak!!!!!!!
