The FAA is reminding operators of Part 25 transport-category aircraft that speeds greater than 250 knots indicated airspeed (kias) below 10,000 feet msl are prohibited unless the aircraft design dictates a higher minimum safe airspeed.

In a newly released Information for Operators (InFO 26010), the agency noted that Part 91.117(a) restricts the higher speed at altitudes lower than 10,000 feet except in cases that qualify under 91.117(d). If the minimum safe airspeed is more than 250 kias, then the aircraft can be operated at the minimum safe airspeed, the FAA explained.
