Black Jake - I think you will find that anybody getting as far as starting up a web browser has already got a brain
Situational awareness, in flying, mostly means knowing where one is.
It is no use posting that one needs a brain also; that is just a waste or bandwidth.
And the best way to know where one is, laterally, is a moving map GPS.
The reason I bang on about this is because large chunks of the GA community still have not got that far and are fumbling and stumbling with their stopwatches and not doing what they originally learnt to fly for which is to enjoy flying.
There is a substantial body of individuals in GA who just keep banging on about how hard everything should be, how one should be tense, how one should expect the plane to blow up any second, etc. It's a good job they are not writing the regs. I wish this was Usenet because then I could stick them into a killfile and be done with them.
