I can't see how CASA can be happy with frictions, as the CAO's state "controls locked", if you go with the proper definition of a lock:
1) A device operated by a key, combination, or keycard and used, as on a door, for holding, closing, or securing.
2) A section of a waterway, such as a canal, closed off with gates, in which vessels in transit are raised or lowered by raising or lowering the water level of that section.
3) A mechanism in a firearm for exploding the charge.
4) An interlocking or entanglement of elements or parts.
The above definition requires the helicopter controls to be locked with either a key, combination or keycard.
I know this would mean there would be no hot refuelling carried out, unless some engineer has designed a lockable collective/cyclic!
It doesn't mention engine at idle in the CAOs either but common sense would prevail, unfortunately in a court of law, legal documents would outweigh good, old common sense!
I also have another bone of contention with CASA and the wording of their documents in regard to sling loads over public areas, but I have let of enough steam for the moment.
