Editing Flight recorder (section)

==== Image recorders ====
The NTSB has asked for the installation of cockpit image recorders in large transport aircraft to provide information that would supplement existing CVR and FDR data in accident investigations. They have recommended that image recorders be placed into smaller aircraft that are not required to have a CVR or FDR.<ref name="ntsb"/> The rationale is that what is seen on an instrument by the pilots of an aircraft is not necessarily the same as the data sent to the display device. This is particularly true of aircraft equipped with electronic displays ([[Cathode-ray tube|CRT]] or [[LCD]]). A mechanical instrument panel is likely to preserve its last indications, but this is not the case with an electronic display. Such systems, estimated to cost less than $8,000 installed, typically consist of a camera and microphone located in the cockpit to continuously record cockpit instrumentation, the outside viewing area, engine sounds, radio communications, and ambient cockpit sounds. As with conventional CVRs and FDRs, data from such a system is stored in a crash-protected unit to ensure survivability.<ref name="ntsb" />{{better source needed example|reason=unclear where this source says this|date=July 2019}} Since the recorders can sometimes be crushed into unreadable pieces, or even located in deep water, some modern units are self-ejecting (taking advantage of [[kinetic energy]] at impact to separate themselves from the aircraft) and also equipped with [[radio]] [[emergency locator transmitter]]s and [[sonar]] underwater locator beacons to aid in their location.<ref>{{Cite web|title=These Black Boxes Are Designed to Eject Themselves in a Plane Crash|url=https://www.travelandleisure.com/airlines-airports/airbus-self-ejecting-black-boxes|access-date=October 5, 2021|website=Travel + Leisure|language=en|archive-date=October 5, 2021|archive-url=https://web.archive.org/web/20211005220134/https://www.travelandleisure.com/airlines-airports/airbus-self-ejecting-black-boxes|url-status=live}}</ref>
