I do not disagree with you, FLARM does help, with the emphasis on help, it

does not replace or indeed lessen the necessity for a good lookout. My

argument was contering the statement that, "The difference between midairs

and all other cause of accidents is that it is the only type which you can

do almost nothing to prevent it, except using flarm." which I think you

will agree is a load of total ********. FLARM can assit the aware pilot, it

is NOT the answer to preventing mid air collisions.

Statically it is. Midairs, once the number 1 accident cause, are now almost nonexistent in Switzerland, since the introduction of Flarm.

You can also assume that no pilot wants a midair collision and maintains good look out. But there are limitations to the human senses, as stated by Gerhard.

We have to stop threating the glider pilot as a luminous all seeing perfect elite being. (paron the pun.) We make mistakes. Hundreds each flight. In fact its a human quality to err.

Here is where technology helps. It maintains its constant SA and fills in our human attention gaps.
