I have had the same question for some time. Would an operator need to 
change frequency that often in flight? If the practice was to "net" all 
of the transmitters before takeoff, wouldn't it be quicker to do it with 
an airfield reference?  How accurate would it be at 20 degrees below 
zero at 25,000 feet?
