Cockpit Image Recorder Recommendation
The U.S. National Transportation Safety Board 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 also recommended image recorders be placed into smaller aircraft that are not required to have a CVR or FDR. 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 (CRT or LCD). A mechanical instrument is likely to preserve its last indication 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.

Famous quotes containing the word image:
“You make yourselves out to be shepherds of the flock and yet you allow your sheep to live in filth and poverty. And if they try and raise their voices against it, you calm them by telling them their suffering is the will of God. Sheep, indeed. Are we sheep to be herded and sheared by a handful of owners? I was taught man was made in the image of God, not a sheep.”
—Philip Dunne (1908–1992)
