LCY DIVERTS -
Due to WIP on RWY28 ILS - the performance criteria changes dramatically due the nature of the approach patterns and surrounding terrain. Radar can decend the aircraft to 1800 feet but pilots must have the PAPI's visual before any futher decent. This means the weather minima is 1700 ft ceiling and a visibility of 7kms. The weather and wind direction were issues today which meant trying to land on rwy 10 with a tailwind which is great for a Fokker 50 but not good for a full RJ100!!
