While the term space weather may at first invoke visions of Capt. Kirk and his starship Enterprise encountering ion storms, it is in reality something which affects radio communications, satellite transmissions and signals intelligence. And because HF radio is particularly susceptible, it often forces airlines and any other aircraft operating on polar routes to switch to different tracks, and sometimes make unscheduled fuel stops.

A 32-year-old advisory circular still used as the basis for showing compliance with in-flight icing protection rules is currently undergoing an “extensive” revision, and the FAA has published a draft version of it for comments.

As I prepared to write this column the television and radio news programs were reporting on the recent spate of business aviation accidents. One of the widely reported accidents that caused considerable concern at the NTSB was the November 28 crash of the Challenger 601 in Montrose, Colo. In this accident the NTSB is investigating airplane performance issues, including the possibility of upper-surface wing ice contamination.
