AAIB Report
Interesting that the AAIB report says:
It is a widely held view in the flying training community that the CAA will take firm action against those who break the rule, regardless of whether the transgressors are doing so in a reckless fashion or inadvertently breaking the rule as part of a responsibly planned and realistically carried out training exercise.
The BA Flying Club instructor who was wrongly prosecuted a few years ago could confirm 'the widely held view' is accurate.
