Sorry must hand you the shovel. CAT A refers to the helicopter not the procedure. Under JAROPS there are now 3 performance classess. You require a CAT A helicopter to perform Class 1 and 2 procedures
Class 1 which equates to the old Cat A ie critical engine stops anywhere and helicopter can continue to fly away or land safely in the reject area.
Class 2 which equates to the old Cat A restricted, ie critical engine stops and helicopter can continue to fly away but if failure occurs early during t/off or late in landing phase a forced landing may be required.
Class 3 where the performance is such that an engine failure in flight may result in a force landing in a multi engined helicopter but will be required in a single
The CAA allow class 2 performance for operation to an elevated helipad (oil rig) so why can't the police/AA arrange the same dispensation.
It is all about risk management. Is it more likely an engine will stop at a critical time or will you be hit by a FJ because your lookout is restricted by procedure limitations. Is it safer to land in a field with a better approach/dep path which allows Class 1 performance but is further from the casualty who may need instant attention. Can you move after dropping off the medics to a safer t/off point. These are all questions that an exp pilot should be asking.
It seems that not enough is being done on BOTH sides to alleviate the danger.
