This discussion is about the benefits of strobes - EC (and which system) deserves a separate thread - if not a different forum! ... but see below.
About Martin's links - I've just skim read the USAF one (I've read and reviewed a lot of documents of that style in my past so I know how to do it) and find two interesting points on pages 142 and 143 of the document:
5.1 "g. Strobe lights will not significantly reduce the potential for mid-air collisions involving Air Force aircraft. The visibility enhancement characteristics of the strobe light when compared to the mid-air threat environment, offer very little, if any, added protection against midair collisions."
and
"5.2 CONCLUSIONS a. Analysis fails to support high intensity strobes for the reduction of the daytime mid-air collision potential with present day technology."
I rest my case m'lud.
However... 5.1"f. Aircraft can be detected at ranges three times greater when the pilot knows the approximate location of the intruding aircraft." supports the use of a radar traffic service (if you can get one) or EC (but which??? - please answer in a different thread.)
