Similar recommendations have been formulated in the 2nd BEA report. (source: BEA-AF447-Interim Report 17-DEC-2010, pp71f)

On the basis of this work, le BEA recommends that EASA and ICAO:
1. extend as rapidly as possible to 90 days the regulatory transmission
time for ULB’s installed on flight recorders on airplanes performing
public transport flights over maritime areas;
2. make it mandatory, as rapidly as possible, for airplanes performing
public transport flights over maritime areas to be equipped with
an additional ULB capable of transmitting on a frequency (for
example between 8.5 kHz and 9.5 kHz) and for a duration adapted
to the pre-localisation of wreckage;
3. study the possibility of making it mandatory for airplanes
performing public transport flights to regularly transmit basic
flight parameters (for example position, altitude, speed, heading).
In addition, the BEA recommends that ICAO:
4. ask the FLIRECP(19) group to establish proposals on the conditions
for implementing deployable recorders of the Eurocae ED-112
type for airplanes performing public transport flights.
