I don't disagree that recording a sortie can have it's benefits and when used properly can indeed be an effective debriefing tool and indeed, approved cameras and recording software are available for even the smallest cockpits. I don't feel that an instructor filming with the device in his hand or a student's field of view being impaired by a 'dash' mounted camera is prudent. I've seen too many solo consolidation exercises and even first solo's used as social media opportunities with GoPro's in one hand or somehow supported in the cockpit, to know that they are an unnecessary distraction. Maybe that's why they call me 'old fashioned'?
