Recommendation text

1. INCREASE THE NUMBER OF AVIATION WEATHER OBSERVING SITES. 2. VIGOROUS PROGRAM OF QUALITY CONTROL OF AVIATION WEATHER OBSERVATIONS SHOULD BE DEVELOPED. 3. CLOUD-HEIGHT MEASURING EQUIPMENT SHOULD BE PROVIDED AT ALL AVIATION WEATHER OBSERVING STATIONS. 4. ADDITIONAL EFFORTS SHOULD BE MADE TO STANDARDIZE THE LOCATION OF WEATHER INSTRUMENTS AT AIRPORTS. 5. METHODS SHOULD BE DEVELOPED FOR MEASURING AND FORECASTING LOW LEVEL WIND SHEAR IN THE TERMINAL AREA. 6. IN ORDER TO INSURE MORE ACCURATE VISIBILITY OBSERVATIONS, ADEQUATE VISIBILITY REFERENCE MARKERS (PARTICULARLY NIGHTTIME MARKERS) SHOULD BE PROVIDED FOR THE GUIDANCE OF OBSERVERS. 7. CONTINUED EFFORTS SHOULD BE MADE TO EXPAND THE UPPER-AIR OBSERVING NETWORK AND TO INCREASE THE NUMBER OF RAWINSONDE ASCENTS TO FOUR PERDAY. 8. THE WEATHER RADAR NETWORK SHOULD BE EXPANDED, PARTICULARLY WEST OF APPROXIMATELY 100 DEGREE WEST LONGITUDE, AND WEAK, OBSOLETE, WAR-SURPLUS EQUIPMENT SHOULD BE REPLACED WITH UP-TO-DATE, LONG-RANGE WEATHER RADAR SETS. 9. IT IS RECOGNIZED THAT IT IS GENERALLY IMPRACTICAL TO BASE A STAFFING PLAN ON THE "BAD WEATHER" SITUATION. IT APPEARS, HOWEVER, THAT SOME REVISIONS OR EXPANSIONS ARE REQUIRED, SO THAT A CONTINUOUS WEATHER WATCH COULD BE MAINTAINED AND IMPROVED PILOT BRIEFING SERVICES PROVIDED AT THOSE LOCATIONS MANNED BY ONE PERSON DURING CERTAIN HOURS. 10. CONTINUE THE EXPANSION OF THE RUNWAY VISUAL RANGE (RVR) PROGRAM INCLUDING THE MULTIPLE INSTALLATION OF TRANSMISSOMETERS. 11. A MEANS OF MEASURING SLANT VISIBILITY OR SLANT VISUAL RANGE WHICH A PILOT WOULD EXPERIENCE ON AN APPROACH TO LANDING WOULD CERTAINLY ENHANCE AIR SAFETY. 12. IN VIEW OF THE ENTHUSIASTIC SUPPORT BY THE USERS OF THE PILOT-TO-FORECASTER EXPERIMENTAL PROGRAMS AT KANSAS CITY AND WASHINGTON, IT IS SUGGESTED THAT SERIOUS CONSIDERATION BE GIVEN TO ESTABLISHING AN OPERATIONAL PROGRAM ON A NATIONAL BASIS. 13. THE TRANSCRIBED WEATHER BROADCASTS (TWEB) NETWORK SHOULD BE EXPANDED TO PROVIDE COAST-TO-COAST COVERAGE. 14. THE PILOTS AUTOMATIC TELEPHONE WEATHER ANSWERING SERVICE (PATWAS) SHOULD BE GREATLY EXPANDED TO PROVIDE ITS SERVICE TO MANY ADDITIONAL AREAS, PARTICULARLY THOSE AREAS WHERE LIVE WEATHER BRIEFING MAY NOT NOW BE AVAILABLE. 15. THERE IS A NEED FOR MORE PILOT WEATHER BRIEFING FACILITIES. 16. SUBSTANTIAL IMPROVEMENTS IN WEATHER BRIEFINGS COULD BE REALIZED BY THE PROVISION OF FACSIMILE EQUIPMENT FOR ALL WEATHER BRIEFING FACILITIES. THIS WOULD ALSO ASSIST IN THE DESIRED STANDARDIZATION OF PILOT WEATHER BRIEFING PROCEDURES. 17. ADDITIONAL EFFORTS SHOULD BE MADE TO IMPROVE AND STANDARDIZE WEATHER BRIEFING DISPLAYS. 18. PROVISION SHOULD BE MADE FOR ADDITIONAL TELEPHONE LINES TO WEATHER BRIEFING FACILITIES. 19. IN ORDER TO ASSIST THE SAFETY BOARD IN ACCIDENT INVESTIGATIONS AND FOR ESSA/FAA QUALITY CONTROL PURPOSES, AUDIO RECORDING OF PILOT WEATHER BRIEFINGS IS ADVOCATED. 20. AVIATION STANDS TO BENEFIT FROM INFORMATION DERIVED FROM WEATHER SATELLITES. ACCORDINGLY, IT IS CONSIDERED THAT SPECIAL
