Heathrow is resurfacing the southern runway this year. From 3 March to 31 October 2013, Sunday evening to Friday morning inclusive, there will be no night-time runway alternation and planes flying after 10:30 pm and before 6:00 am will use the northern runway. EFRA's area is not directly under the northern runway flightpath but even so we are likely to notice more night-time and early morning aircraft noise during this time.
