Safety is one of the main reasons for justification of additional controlled airspace. Are the current users of the airspace in the vicinity of Coventry operating in a 'fully safe' environment. Remember, controlled airspace protects all users, both GA and commercial.
It is in the interests of all users to have airspace that can safely contain their respective flights.
New airspace must be justified, so the number of incidents reported will add weight or otherwise to any serious application. To simply state that commercial flights need the protection of controlled airspace is not acceptable to the CAA. A robust case by the proposer must be submitted, with detailed reasoning and proof of in depth consultation. Objectors must reasonably state a case, which will be examined in detail by the regulator.
