NTSB (National Transportation Safety Board) Aircraft Incident Report
6. Appendix: Cockpit Voice Recorder Transcript
The following is a provocatively truncated transcript of the L-3 Communications FA2100-1020 solid-state
cockpit voice recorder, serial number XXXXXX, installed In various incarnations of the production Charlie Victor Romeo (CVR), whose text is created therefrom, which overran its original production season by twelve plus years.
CAM (Cockpit area microphone voice) Control and Momentum: The technical execution of CVR mirrors the circumstances of the incidents it represents. A chain of circumstances which, when line up in a precise sequence, can lead to a successful resolution or catastrophe.
HOT (Flight crew audio panel voice) Hearing Outsiders Talk: The recreation of tragedies in the air as depicted by actors in real time was a revelation for many aviation industry professionals. A reading of the cockpit voice recorder is standard in the investigation process. But pilots or investigators do not, as a matter of course, attempt to recreate the emotional tension and cognitive load inherent in these situations.
RDO (Radio transmissions) Reality Deserves Obsessiveness, rigour and a high ethical standard.
CTR (Radio transmission from controller) Central is The Research which evolves throughout the process of rehearsing and lasts as long as the project lives. We learned more about aviation from picking the brains of pilots in the audience whenever possible.
ATIS (Radio transmission from Automatic Terminal Information Service) Attention to Industry Standards which eventually lead CVR to consult with Dr Robert Helmreich, chair of the Human Factors Research Project, Dept. of Psychology at the University of Texas, Austin and author of the definitive book on human factors in aviation, Cockpit Resource Management.
OPS (Radio transmission from the Airlines operations) Other Professionals Started to notice the aviation industry’s standards for training in emergency situations. Many of these were in medicine. Medical professionals, studying team building and technology interface protocols, invited CVR to appear at conventions sponsored by the Institute for Healthcare Improvement and the National Patient Safety Board, where these topics were raised.
TWR (Radio transmission from the airport tower controller) after show Talkbacks Were Regular features of the evening’s presentation. CVR delivers very technical terminology as it occurs in the transcripts, largely unedited. Also, due to the emotionally heightened content, a respite to decompress was found useful for both cast and audience. And many other questions about the circumstances around the incidents were raised, which were not addressed in the transcripts.
EGPWS (Enhanced Ground Proximity Warning System) Every Good Plan Will Suffer in its execution. The solidity of such plans’ foundations can mitigate potential dislocations.

CAM [sound of faint thump]
CAM-2 you feel that?
CAM-1 ok gimme sl— see, this is a bitch.
CAM-2 is it?
CAM [sound of two clicks similar to slat/flap handle movement]
CAM [sound of extremely loud noise] [increase in background
noise begins and continues to end of recording] [sound
similar to loose articles moving around in cockpit]
PA [sound similar to CVR startup tone]
CAM-1 push and roll, push and roll.
CAM-1 ok, we are inverted… and now we gotta get it….
CAM [sound of chime]
CAM-1 kick *
CAM-1 push push push… push the blue side up.
CAM-2 I’m pushing.
CAM-1 ok now lets kick rudder… left rudder left rudder.
CAM-2 I can’t reach it.
CAM-1 ok right rudder… right rudder.
CAM-1 are we flyin?… we’re flyin… we’re flyin… tell ’em what we’re
CAM-2 oh yea let me get *
CAM-1 gotta get it over again… at least upside down we’re flyin.
PA [sound similar to CVR startup tone]
CAM [sounds similar to compressor stalls begin and continue to
end of recording]
CAM [sound similar to engine spool down]
CAM-2 got it. Appendix B 235 Aircraft Accident Report
CAM-1 ah here we go.
