In a letter to the Federal Aviation Administration (FAA), the NTSB said, “Recent events have highlighted that recovering flight data can be costly and difficult when an accident occurs in a remote area, outside radar coverage.” To prevent such difficulties, the NTSB has recommended installation of tamper-resistant location transmission devices in all aircrafts.

Furthermore, the NTSB called for regulations mandating that the flight data and cockpit voice recorders of all commercial airliners be equipped with low-frequency underwater beacons capable of being easily located.

Cockpit video recorders and longer lasting batteries on the beacons are also among other recommendations submitted for consideration by the FAA.
