I dont think people realise you can be in beta RANGE without selecting reverse, they are not the same animal.
I think every person who has flown a PT6 powered aircraft has been in Beta RANGE totally legally. Beta RANGE is when the prop speed is controlled by the power lever, i.e. taxi, and often on final approach. Beta range is not the same as reverse range, however the reverse range can also be considered in the beta range.
Alfa RANGE is when the prop levers control blade angle.
I do not agree with your comments about "bush technique of “cracking it into Beta” is not an approved method of operation in any of the Twin Otter" as the aircraft is in flight idle". It happens every day, totally legal.
Sorry to digress, please continue.
