Following the death of Her Majesty Queen Elizabeth II, as part of the overall security arrangements, several temporary airspace restrictions are already in force. Currently, the two temporary restrictions are: * RESTRICTION OF FLYING REGULATIONS: BALMORAL CASTLE TO THE PALACE OF HOLYROODHOUSE, EDINBURGH 10 – 13 SEPTEMBER 2022. The briefing sheet for this restriction can be found here. * RESTRICTION OF FLYING REGULATIONS: CENTRAL LONDON, 9 SEPTEMBER – 19 SEPTEMBER 2022.The briefing sheet for this restriction can be found here. The official source to obtain accurate and complete Aeronautical Information in the UK is the UK Aeronautical Information Publication (AIP), which contains details of all permanent airspace restrictions, and separately, details of temporary restrictions. In this instance, due to the short notice nature of these restrictions, they are promulgated as briefing sheets within the Aeronautical Information System, here. Please be aware that further restrictions will come into force in the coming days. We strongly recommend that you continue to monitor official sources of data regularly. 12 September 2022
