It was cleared.

I got original manual for SPitfire MK II from July 1940 where it is emergency boost +12 boost allowed for take off or for 3 minutes.

"Take-off" boost is not the same as "emergency" boost. See Pilot's Note General (1st Edition, June 1941):



The description exactly applies to the Spitfire II. There was a "gate" for "take-off" boost and a "cut-out" for emergency power.

From July 1940





and another manual (probably later)
