An update from RAF Northolt this afternoon, who report there will be extra flight activity during the night on Monday and Wednesday night/following morning ….
“RAF Northolt will have one of its periodic checks of its flight safety radar systems on 2-3 Feb 15 from 11pm to 4am and again on 3-4 Feb 15 from 11pm to 4am. Only one aircraft will be operating from RAF Northolt throughout the period, making repeated approaches to the runway. The first night will calibrate the Instrument Landing System to Runway 25 (approaching from the east over Ruislip) and the second night will calibrate the Precision Approach Radar to Runway 07 (approaching from the west over Ickenham). These calibration flights are an essential safety assurance process and have to take place when Heathrow is closed.”
As always, the calibration flights will be subject to acceptable weather conditions and may be rescheduled if the weather is not suitable. RAF Northolt apologises for any disruption caused to local residents and appreciates the continued support and understanding of the local community in ensuring that the Station operates to the highest safety standards.”
