The associated notes to the APBSS chart are clearly going to be critical - what did they say, and were they read. Given that these were standard notes presumably available to all flight crew and others across a four base IRCG SAR operation over the last 5 years, and are also considered likely to be legacy notes created many years ago and therefore used by quite a few other pilots, I assume there are quite a few reading this thread who know exactly what these notes say. And what they were intended for. Anyone care to comment?
