...any idea how we can get each air ambo casualty up to the same speed?!
Maybe you don't have to...(exceptions)
...Couldn't air ambulances be classed as charity flights?
5.2 Exception No 2 - Charity flights (Article 159)
A flight will be deemed to be a private flight for all purposes if the only payment is to a registered charity which is not the operator of the aircraft and the flight is made with the permission in writing of the Authority.
But in the case of an air ambulance, perhaps it is down to payment..
3.3 Valuable Consideration
Throughout this paper, the question of whether a flight is public transport or aerial work is discussed in terms of whether "payment" has been given or promised in respect of the flight. In the Order itself instead of "payment" the term which is used is "valuable consideration". This term has a very wide meaning, including the provision of goods and services.
4 How to determine whether or not a flight is public transport.
4.2 Having determined that there is at least one passenger on board, the next question is whether any payment has been given or promised which, if it had not been given or promised would mean that the passengers would not have been carried.
