Facinating analysis - thank you once more mm flynn.
If I have understood it-
Over 90% of UK registered aircraft are GA, and they only account for one third of serious losses of separation.
Two thirds are down to professional pilots using ATC in Controlled Airspace.
I am not criticising - mea culpa, having had a FL100/FL110 clearance confusion & level bust - just musing about proportionality.
Of the one third of losses of separation, about two thirds are down to navigational errors.
Moving maps with Airspace warnings are relatively so cheap, low power and readily available for most recreational aircraft that there is scope for dramatically reducing GA Infringements, ATC workload, risks and disruption costs. Prevention being better than cure?
I have two in my glider.
GASCO are encouraging moving maps.
If Notams were provided graphically on an official web site, infringements of temporary airspace, might also be dramatically reduced. An official version of "Notam Map" or similar would help a lot. Even better if the airspace was downloadable into the moving map.
Are TMZ's and extended mode s mandates the best and most proportional answer?
