NTSB Safety Recommendation — Aviation
Recommendation text
REPHRASE THE WORDING CONTAINED IN YOUR ALTITUDE/AIRSPEED LIMITATIONS AND DELINEATE EXPLICITLY THOSE INSTANCES WHEREIN AIRSPEEDS IN EXCESS OF 10,000 FEET/250 KIAS LIMITATIONS ARE AUTHORIZED. THE BOARD BELIEVES THAT THE EXCEPTIONS SHOULD BE LIMITED TO THE FOLLOWING: A. CLIMBS AND DESCENTS TO TRAFFIC PATTERNS, AUTHORIZED AND/OR DESIGNATED TRAINING AREAS AND LOW-LEVEL NAVIGATION ROUTES. B. THOSE INSTANCES WHERE SAFETY OF EITHER CREW OR AIRCRAFT REQUIRE OPERATIONS IN EXCESS OF THE LIMITATION.
In plain language (FlightFinder summary)
The NTSB advised the Department of War to clarify its rules regarding altitude and speed limits by clearly listing when flying faster than 250 knots below 10,000 feet is allowed. These exceptions should be restricted to specific situations, such as traveling to training areas or navigation routes, or when necessary for the safety of the crew and aircraft.
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.
