By day, whenVMC does not exist, theATCunit responsible for aCTRmay
authorise, at pilot request, a Special VFRflight in theCTR, or in aCTAnext to
theCTR for the purpose of entering or leaving theCTR, provided that:
• theSpecial VFR flightwill not unduly delay an IFRflight; and
• the flight can be conducted clear of cloud; and
• the visibility is not less than 800m (for helicopters); and
• a helicopterwill be operated at such a speed that the pilot has adequate
