Are any companies leaving one Thales probe on or are they replacing all three? Leaving one might allow useful data to be collected?

EASA stopped short of banning the Thales probes outright, allowing operators to continue to use the so-called -BA standard as a third sensor on Airbus widebodies. A regulatory official says continued use of one Thales -BA probe is "probably acceptable."
