CASA has published NPRM 1309OS. Details are here:
Civil Aviation Safety Authority - NPRM 1309OS and responses are open until 16 June
This amendment to CASR Part 101 relates to Remotely Piloted Aircraft (RPA) used for commercial operations, but excludes model aircraft used for recreational purposes. It establishes a revised risk based framework for regulating RPA operations. A key part of this amendment acknowledges the existence of a "low risk" class of RPA operations, which are determined as small RPA with a gross weight of 2 kilograms and below while they are being operated under the standard RPA operating conditions as defined and discussed in this NPRM.
For these RPA operations, CASA proposes that the requirements for a Remote Pilot (RP) Certificate or an Unmanned Aircraft System Operator’s Certificate (UOC) will not apply.
RPA with a gross weight above 2 kilograms in all operating conditions, and all RPA operating outside of the standard RPA operating conditions, will require an operational approval.
