Single Engine Charter
CASA and most regulators ban S/E charter, wanting to give the paid customer a better chance of survival if the engine fails.
There are exceptions. The prop turbine PC12, the C208 and the TBM but only if they have been specifically approved by CASA for S/E charter ops.
In Australia one Cirrus sales guy was keen to get Cirrus singles approved working on the basis that the emergency parachute gives the customers a safe ride. The Cirrus is not approved at this time. Thus Cirrus singles are not approved for charter as far as I am aware.
