Hughes - if perhaps HC and DB could dismount from their high horses they might see that what you did was completely fair, not even remotely dangerous and actually good post-PPL instruction.
You established, without drama, the limited extent of the student's aircraft knowledge, retention of taught emergencies and ability to think through a problem that might present itself in the air for real.
DB - no-one said mil pilots don't crash - either in training or operationally - but this thread was started to highlight 2 very preventable accidents and you know how much value the mil puts on doing that. Your rather rigid attitude to instruction is perhaps why people like Geoffersincornwall are complaining about the poor standard of training and flying in civil ops. Box-ticking to meet regulated minima doesn't make for good pilots.
