VIII. Battery Life / Deployable Flight Recorders / Solar Panels
Another limitation with the current technology is that batteries within the flight

data recorders on an average last only up to 30 days. This presents a real problem if

the search for the wreckage takes longer than 30 days such as in the search for

Malaysia flight 370. One possible solution is to extend the life of the batteries to a

longer period, e.g, 30-120 days, is by adding a solar charging system to the current

technology.. After Malaysia 370, some commentators called for the battery life of the

underwater locator beacons to be extended from 30 to 90 days, the range of the

locator to be increased and additionally for the outfitting of civil aircraft with

deployable flight recorders, commonly used in military aircraft
