I don't see any reference to a CAI file not do I think the 302 can

p.s.

The assertion that a CAI file is more secure than the IGC file relates
to Cambridge recorders that pre-date the 302 series. Those earlier
recorders produced ONLY a CAI file and it has to be post processed to
create an IGC file that then has no security.
