Many cockpit crewmembers believe the ingestion of ice crystals by a jet engine is essentially harmless if the engine’s igniters are turned on. However, aeronautical engineers generally do not agree, citing incidents when mixing ice with standard intake air resulted in a noticeable reduction in engine power output and, at its worst, a complete engine flameout. Ice formation inside an engine compartment can also lead to indicator anomalies that may not shut down the engine, but may lead to air data system failures.

University of Cambridge Professor Holger Babinsky has created a one-minute video to dispel the myth that an airplane wing generates lift because the airflow moving over the upper surface has a longer distance to travel and “needs to go faster to have the same transit time as the air traveling along the lower, flat surface.” What actually causes lift, he said, “is introducing a shape into the airflow, which curves the streamlines and introduces pressure changes–lower pressure on the upper surface and higher pressure on the lower surface.
