Set to run over Darwin, Australia, between Jan and Mar 13, NASA GRC is setting up the final preparations for analysing ice particles from Cb Incus and their surprising effects inside jet engines.

The investigation deals with the seemingly strange notion that ice crystals associated with warm-weather storms can be ingested into the core of a jet engine, melt and then re-freeze, potentially causing the engine to lose power or shut down altogether. Safety officials have documented more than 150 incidents of this phenomenon since 1988. Most of the incidents have occurred in the tropics.

For now, pilots are being trained to recognize the potential existence of these ice crystals, which are about the same size as baking soda, and advised to avoid the weather conditions as best they can. Although a potential hazard, no accident has been attributed to the phenomenon in the 23 years since it was identified.

It is expected that updated flight safety rules and engine testing standards will be adopted once all the research is compiled and analyzed during the next few years.



NB: this is ice inside the engine, not the airspeed indicators as proposed for the fault in the Air France F-447 incident.
