Response: This safety recommendation addresses a need for development of a thorough convective weather refresher course as part of recurring training for all personnel actively engaged in the control of air traffic. The Safety Board notes that the FAA has developed the recommended course and will release it with the next revision to FAA Order 3120.4.

To: NTSB
Date: 5/23/1989
Response: THE FAA HAS DEVELOPED A NEW REFRESHER TRAINING COURSE ENTITLED "SEVERE WEATHER." THIS TRAINING COURSE CONCENTRATES ON THUNDERSTORM ACTIVITY AND INCLUDES INFORMATION ON HOW WEATHER PATTERNS DEVELOP. THIS TRAINING COURSE WILL BE INCLUDED IN THE NEXT REVISION TO FAA ORDER 3120.4 WHICH DELINEATES REQUIREMENTS FOR REFRESHER TRAINING TO BE CONDUCTED IN FIELD FACILITIES. I BELIEVE THAT THE FAA HAS MET THE INTENT OF THIS SAFETY RECOMMENDATION, AND I CONSIDER THE FAA'S ACTION TO BE COMPLETED.
