The award of a Pilot’s flying badge is provisional until confirmed in accordance with current rules. When I was awarded my badge it was 6 months on an operational Sqn or, for creamies award of a B1.
Currently I believe it is CR (or maybe (LCR) and B1 for creamies.
The only exception I know of is where an individual is medically downgraded, following an accident say, before they can confirm the award. This is discretionary on a case by case basis.
