Sure, heavy metal and GA are two different animals. Jet transports dispatch with 60 minutes over destination, most load more on. When I’m down to 48 minutes the fuel LOW checklist comes out! GA has a more ‘limits as targets’ mindset. For example, if the new FFR was 10 minutes quite a few pilots would be comfortable.
If I were a young GA pilot and I knew CASA were proactive, I would always turn up with a comfortable margin above FFR. The $10.5K fine wouldn’t be worth the risk.
