Response: A-74-12: THE FAA DOES NOT BELIEVE THAT CONTROLLERS SHOULD ASSUME THE RESPONSIBILITY FOR DENIAL OF CLEARANCES BASED ON THEIR ASSESSMENT OFTHE HAZARDS ATTENDANT TO THUNDERSTORM ACTIVITY AND THAT THE "GO-NO-GO" DECISION MAKING RESPONSIBILITY SHOULD REMAIN WITH THE PILOT-IN-COMMAND. THEY ARGUE THAT CONTROLLERS ARE NEITHER TRAINED NOR QUALIFIED TO MAKE THIS KIND OF JUDGMENT; NOR DO THEY HAVE THE EQUIPMENT TO AID THEM IN REACHING THIS KIND OF DEVISION.
