I must agree with snap as we have had many conversations about this and have spent a couple of hundred hours flying together. I must admit that there is very little that we haven't seen together and apart from a few tech problems both of us agree that most of our workload is spent transiting around glider sites. I am afraid to say gentlemen that you are very difficult if not impossible to see.
We know where you hang out and areas that you are likely to be, but believe it or not the UK airspace is very very crowded.
It is a shame to say it but there are bad pilots in all catagories. The post was about what can be done about being conspicuous not that you have 150 hrs. So lets get back to the point and look at what can be done by owners, before you are regulated.
Does anybody have any idea how many gliders and microlights for that matter have a radio and transponder.
