The old trick question "can a PPL holder fly in IMC without an instrument qualification"
Actually you mean IFR not IMC. To fly in IMC you need an appropriate qualification however; a UK National Licence holder could fly IFR outside controlled airspace withou any instrument qualification. A JAA licence holder has never had that privilege as the ANO stated that the licence was subject to JAR-FCL 1.175, which stated you cannot fly IFR without an Instrument qualification, even in VMC. This of course has transferred across to EASA and even prevented night flying without the exemption that has now been issued.
