It may appear 'absurd', but remember that the CVR/FDR provisions that exist in FAR 25 aircraft are there by regulation. Yes, technology has advanced since those regulations were first enacted, however, it would be an interesting exercise to review the regulations to see if the off-board real-time transmission of the FDR/CVR data would satisfy the current regulations, or a case could be made in respect of an equivalent safety finding. A great idea. Another fail-safe avionics subsystem for the major airframers to develop and certify means someone is going to have to pay for it. I wonder if the commercial airlines are going to push for this ? You'd think it would be a 'no brainer' ?
