If you are taxiing to your take off point and there is lots of CB activity, heavy downpours etc can the weather radar on your aircraft give you accurate information while you are on the ground, or do you have to ask ATC to see if they can give you up to date information?

Have you got to be clear all around on take off, if the standard departure is a right turn after take off and there are some nasty CB's on the radar to the left could you ignore those as you will not be going left, or do you have to factor them in and just assume, that maybe, just maybe, you might have to turn left to avoid traffic if there was a problem?

I try not to zap other airplanes but I do like a good sweep before I take off, especially in those quadrants where I expect to be flying. So ideally, I might be in standby until I'm number one to turn the corner onto the runway. Then I'll fire it up on shortish range and a high antenna angle and look things over. Leave it in that mode as I turn the corner and line up. Now it is sweeping the departure corridor, my area of greatest interest.
You don't want to use it so close behind another plane that you start cooking the meals in their galleys, short out the senior flight attendants' pacemakers and so on.

Not the same thing (lower power) but... when we installed radar on my dad's boat it was mounted on a crossbar about a metre above the deck of the flybridge so when you were sitting up there the beam "sliced" through your head. The supplier and the manufacturer reckoned that, as your head only occupied a small sector of the sweep, you'd be OK. They did, however discourage standing in the sweep zone.

Quoting Zeke (Reply 5): Dont know about those 1950s/60s radars in 727/737.
The only recorded incident I can recall was that first officer getting some pictures of him taken infront of his DC-9, then with a virile pose with his hand on the radome...you see what I mean. Ended up with some damage to the brain, loss of licence etc...
A physician told me at that time that research had shown that normally the blood stream was enough to provide cooling to tissues being heated by the then radar beams, except the brain as most of the blood circulation was through capillary veins with not enough flow to have any efficient cooling effect.
