Hi Shawn
The JAR definition (Appendix 1 to JAR OPS 3.465) is essentially the same as the UK ANO one. For info the JAA MMELs now add the statement that
"when the FAA MMEL or JAA Supplement restrict flight to "VFR" and the operator intends to use this restriction at night, then operations must be conducted with adequate external attitude reference and in sight of the surface at all times".
Cheers
Steve
