Notes for the management of the fuel system stated that indicated airspeeds (IAS) in excess of were not advisable when fitted with auxiliary drop tanks. Tanks were jettisoned at about , but in an emergency, a release at was permitted. Tanks were to be ejected in straight and level flight only. General flying ability was positive. The maximum climbing rate was up to reducing speed by per above this mark. In stability terms, the aircraft was stable "directionally" and "laterally" but slightly unstable longitudinally, except at high speed, when it was just stable. Aileron control was light and effective up to maximum speed, but at very low speed response was sluggish, particularly when carrying ordnance. The elevator control was rather light and should not be used harshly. There was a tendency to "tighten up" in a looping aircraft. If "black out" conditions were accidentally induced in steep turns or aerobatics, the control column was to be pushed forward "firmly".
