I am not suggesting it should be pass/fail. I am suggesting that it should contain either a set list or suggested list of items that should be covered to standardise it. SOME instructors/pilots use it as an opportunity to go for an hour bimble and some actually use it for a valuable refresh of skills that may have not been practised. In some circumstances, pilots will not see the value of this hour and do anything to make it easier for themselves. This does happen.
There is a just culture within infringements and the aviation industry as a whole. If a pilot infringes and they are open, honest and willing to learn about it then the whole episode is used as a learning exercise. It is those pilots who refuse to accept they have done wrong (despite evidence showing they have!) and argue and do everything they can to get out of it, are the ones who go against just culture and don't promote the correct attitudes. And those who know they have just infringed and decide to switch off the transponder have a special place reserved for them....
Sadly, it is the few that ruin it for the many.
