So, I take it you know exactly where the ice is forming on or in the probe, and can tell Thales and Goodyear exactly what is wrong with their designs so they can fix them post haste?
You assume much,
but in defence, did say in the first sentence that the probes may be working outside their original design limits. The design changes may not be trivial but it is, irrespective of how many years of ‘research’ and committee it takes, an engineering problem with a solution. An extrapolation of an existing, well proven and reliable technology. Thought though, is not good enough. One would expect that there would be a process of continuous research and feedback to identify problems proactively. One incidence of a problem noted, several incidences starts to show a pattern. As for the probe heat controller, it’s not exactly rocket science to design one to prevent overheating.
It seems like there have been many reports of probe icing failures over many years. So how many incidences over time does it take before some sense of urgency is attached to the problem. 1, 5, 10 years worth, or what ?. Not a criticism of engineering, more one of process and I do get the feeling that those who should be driving this are in no particular hurry…
