Hope this helps, FAA legal take on this
Essentially if you configure the aircraft to meet a speed requirement than do so.
it mentions minimum safe speed, not minimum clean speed. Someone asked if the could fly a 737 clean, and they turned around and said no, configure the jet.
they also talk about ATC requirements

No it doesn’t.
That interpretation specifies landing aircraft.
The whole truth:
Get this frequently out of LAX. The intent is at 10,000 that you’ll accelerate to 280 kts. The “administrator” can authorize speeds in excess 250 kts below 10,000 (IAH a number of years ago) individual controllers however cannot invoke the administrator’s authority.
Now if you need in excess of 250, that’s a different story.
