5.166 What does an air transport pilot (aeroplane) licence authorise a
person to do?
(1) An air transport pilot (aeroplane) licence authorises the holder of the licence to fly an aeroplane as pilot in command, or co-pilot, while the aeroplane is engaged in any operation.
(2) The authority given by subregulation (1) is subject to the limitations set out in regulations 5.167, 5.168, 5.169, 5.170 and 5.171.
This is the ATPL authorisations, the reference to flying the aircraft must mean that an ATPL holder or CPL holder can not act as PNF then?
Any references to a licence holders privileges will be prefixed with this to enable them to operate an aircraft in flight.
The only casa regulation which pertains to pilot manipulating the controls (pilot flying) is the one with regard to instrument flight time CAO 40. CAR 225 also suggests the PIC need not be seated at a control seat at all as long as a suitably qualified pilot(s)occupy them.
