NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: TAKE IMMEDIATE ACTION TO REDUCE THE MAXIMUM ACCEPTANCE RATES AT THOSE AIRPORTS NOW MONITORED BY THE CENTRAL FLOW CONTROL FACILITY, AND PLACE LIMITS ON EN ROUTE FLIGHTPLAN APPROVAL TO THE EXTENT NECESSARY: TO ENSURE THAT THE PEAK TRAFFIC IN AIR ROUTE TRAFFIC CONTROL CENTER SECTORS RESULTING FROM THE INTERMIXING OF AIRCRAFT DESTINED FOR DIFFERENT AIRPORTS REMAINS AT OR BELOW PRESENT LEVEL; AND TO ENSURE THAT IN-FLIGHT HOLDING IS LIMITED TO UNPREDICTABLE CIRCUMSTANCES UNTIL THESE FACTORS ARE INCLUDED IN AN AUTOMATED PREDICTIVE AIR TRAFFIC CONTROL SYSTEM FLOW CONTROL PROGRAM BASED ON DYNAMIC SITUATION ANALYSIS. (URGENT)
In plain language (FlightFinder summary)
The FAA is asked to immediately reduce maximum acceptance rates at airports monitored by the Central Flow Control Facility and limit en route flightplan approvals. This is required to keep peak traffic in air route traffic control center sectors at or below current levels and to restrict in-flight holding to unpredictable circumstances until an automated predictive flow control program is implemented.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
