 Further instructions ordered all but fighters and night bombers to have Type A under the wing tips.This was clarified in November to the effect that only reconnaissance maritime aircraft (e.g., Short Sunderland flying boats) would have the Type A on the upper wings but all aircraft would use the Type B on the sides.A decision was made to make roundels more conspicuous and, in May 1940, the yellow outer ring was ordered to be added back to fuselage sides (along with red, white, and blue stripes on the fin).
