Up in the flight levels, jets fly at relatively low indicated airspeed and still cruise at 7-8 miles per minute.

Moments after climbing through the ceiling over Beverly, MA. We made an IFR departure that morning on runway 16 and climbed above the ceiling in short order. Approaching the Green Mountains of Vermont, the ceiling began to close back up. This meant that there would be no getting into Sodus unless the ceiling lifted.

You can override the system to manual by lifting a sliding door, but it was honestly completely forgotten within the first half hour of our flight demo. Flap overspeed protection makes for one more improvement, preventing the pilot from deploying the flaps above the programmed indicated airspeed relevant to the flap setting selected.
