Effectively they (Service de Police aux Frontières - SPAF) want
a) for the crew
b) for the passengers
1. Name
2. Date of Birth
3. Travel Document (i.e. passport, ID card, etc...) number
4. Place where boarded
5. Destination (i.e. transit passengers or not)
and then they want aircraft registration and type and specifics of the operation (if applicable).
The UK GAR form pretty much delivers all this info, so a copy of that would do nicely.
