The Civil Aviation Authority annual statistics show a remarkably balanced year, with 20,027 aircraft nominally active, precisely one more than on 1 January 2017. Fixed-wing microlights had a productive year, as did autogyros, and hot-air balloon numbers rose after a long decline. There was a balancing fall in flexwing microlights. Airliners increased, driven by easyjet’s fleet expansion, although this may reverse with strategic reassignment to foreign registers, mostly Austria but also Spain and Guernsey. Exactly one third of the fleet has no current Certificate of Airworthiness or Permit to Fly, although this does include more than 600 exempted by SSDR rules (aircraft of qualifying types were re-allocated this year).
