Interesting to note that Emerald ATR from Belfast City diverted with Runway Condition Code 2 Greater than 1/8 inch (3 mm) depth: Standing Water / Slush Braking deceleration or directional control is between Medium and Poor
Yet the rest are landing OK although no sweeping seems to be getting done, relying on de-icing
Suspect the A388 will need a lot better than Code 2
