Absolutely fair point HWD; however it costs a lot of money to publish and mail out this mag and IMHO it is wasting an opportunity to modernise attitudes in GA.
It's exactly the same with the CAA safety presentations. In fact I wonder if they are done by the same man... can't remember his name but he's well known. Ex RAF I believe.
One can take the charitable view that the UK average PPL annual time is 10-20 hours (I read that on the internet so it must be true) and constantly reminding them of the most basic errors is where money should be spent. If that is the case, it's no wonder pprune readers find it a bit of a bore since I would bet most of them are well above that annual figure.
But aircraft owners will usually be doing a lot more hours (otherwise why own something) so mailing such a "don't forget to rotate when you take off" magazine to them has got to be a waste of resources.
