Sorry; "HEMS or Air Ambulance?", my perennial question as we launched, was in regard to possible use of HEMS exemptions and permissions.
The exemptions and permissions were granted for 'HEMS' flights only, not 'Air Ambulance' flights.
The difference was that a 'HEMS' flight was "where immediate and rapid transportation is essential" An 'Air Ambulance' flight was where this urgency was not deemed to be present and only normal CAT limits could be used.
I simply needed to be told the status of the flight in order to use my HEMS exemptions.
