"A very quick glance over the first few pages of the "Safety Investigation and Data Detarpment Occurence Listing - GA occurrences recorded between 21 May 2005 and 19 Aug 2005" seems to indicate as many infringements by King Airs, Cessna 182's and other types probably using moving map GPS as there are by Cessna 150s (which may also be using moving map GPS)."

You mention two types and a collective "other" - King Airs and Cessna 182s. There is no evidence either of these types carry moving map GPS to a greater or lesser extent than other types. There are also numerous CAS busts that go unreported so the list you refer to is unlikely to give a complete picture.

I would agree that King Air crew will not be low timers but equally the type of CAS busts with which they are involved are not typical of those that plague CZ units.

The trouble is there is not a great deal of definitive evidence whether or not the use of moving maps or other means of navigation are more or less effective in preventing CAS busts.

Perhaps following a CAS bust pilots should be required to complete a questionaire (perhaps in consideration of no further action) for a period of time. This might enable a more relaible picture to evolve of the casue (and whether or not moving maps would have helped prevent the bust).
