Denti:
EGPWS doesn't emit so I don't see the connection to this discussion?

Thanks for the informative link. It seems to mainly focus on ground crew though. And consider this from the article:
...never to place any part of the body in region of the antenna and the feed horn......Doppler X-Band (9300 – 9500 MHz) transmitter with a nominal output of a few hundred watts of microwave power....
We are sitting close to the antenna which is basically a microwave oven.
I know microwave ovens are only dangerous to domestic animals in the States (
) but how would you feel about spending 8 hours a day 2 meters from one while it buzzes away at home?
Also, personally I have never experienced a radar not coming on again after being switched off in flight but I might have been lucky.
I say turn it on when you need it.
