the TRE told me something I had never heard before (I have been flying for 35 years now !)
I first read about that circa 1978 and after that diligently scanned the runway ahead (737-200) prior to departure from Pacific atolls where sea birds concerned us. Had only one bird strike over several years but I always thought it was a dodgy theory. But like believing in God, thought I would cover my arse, "just in case."
Then I happened to read the Collins WXR-700X Pilots guide, (October 1974 edition) and at page 33 it states:
"The average radiated power density of the Collins WXR-700X Weather Radar System is significantly less than the 10mW/cm2 allowable for limiting the exposure of rf energy to humans as noted in FAA Advisory circular, number 20-68B, dated august 1980. The WXR-700X doe not require the use of a dummy load when operated on the ground."
That was in 1974. Presumably the modern radars are safer still?
