safety standards...... good question

means dont be a dumb ass, your looking after your self.
Transmitter pound, the trannys are all put together at the back of the pits, by the peg board, it reduces the cahnce of switching on without the peg and leaving the transmitter on afterwards. at events a person looks after the pound and enforces it.
you use a bungee for launching gliders, the peg is up wind out the way of planes landing, and the pilot must launch from a set point, mine was 300M!!!! peg in the coner of the field and i stood on the patch to launch
Frequency clearence means you must have the peg to fly, we use a peg off system, no peg, no fly
We're not a BMFA club, but we use the guidelines, you've got links to those already
As for the B test thing, its a joke, the B flyers only get to fly at displays and teach if they want to.
