As I think I have said before, the FAA/JAA development of regulations for NVG was a cooperative process - both for certification and operations.
The current JAA guidance resides in JAR-OPS TGL 34 and has been in existence for several years. Reading this TGL will indicate where any (necessary - due to variations in regulatory approaches) differences exist. Credit is given to existing FAA, RTCA or EUROCAE documents where they have been used - or amended and used.
