WASHINGTON - Airline pilots are dead set against putting cameras in cockpits as safety officials step up the pressure to require them as an aid to accident investigation and prevention.
The National Transportation Safety Board launched a two-day hearing Tuesday to renew its call for all civilian planes to be equipped with crash-resistant cockpit image recorders.
Four years ago, the NTSB recommended that the FAA require cameras on large aircraft, but the FAA hasn't done it. Subsequently, the NTSB added small planes to its recommendation.
NTSB senior air safety investigator Frank Hilldrup said cockpit image recorders would produce faster and more accurate conclusions about the causes of accidents.
Supporting the idea was Ken Smart of the British Air Accidents Investigation Branch, who said cameras are used on military aircraft in the United Kingdom and are "very, very useful" in understanding the human actions that lead to airplane accidents.
Nonetheless, the idea of cameras in the cockpits drew strong opposition from airline pilots.
John David of the Allied Pilots Association, which represents pilots at American Airlines, said being monitored would affect their performance.
"It's going to be very intrusive," David said. "You always see the glass lens."
The Air Line Pilots Association, the largest pilots union, issued a statement saying, "The benefits of video imaging are vastly overrated, because far more effective and efficient tools exist."
Advocates of the devices said there are ways to protect pilots' privacy: encrypting the information, for example, or pointing the cameras away from the pilots' heads and shoulders.
But one reason pilots oppose image recorders is that such promises were broken after they agreed to the introduction of cockpit voice recorders in the 1960s, the Air Line Pilots Association told the board.
Pilots had been told the tapes would be used for accident investigations only and wouldn't be publicly disclosed. But in 1989, a 6 o'clock news program played the cockpit voice recorder from Delta Flight 1141, which crashed on takeoff in Dallas. The crew and passengers survived.
Though laws were subsequently passed that limited the use of cockpit voice recordings, they are still used against pilots in criminal proceedings and disciplinary actions by employers, the statement said.
Airlines are skeptical of the cameras. They want a cost-benefit analysis done before they have to pay for the devices.
The safety board maintains that cameras would have helped investigators understand the smoke and fire conditions in the cockpit of two deadly plane crashes: Swissair Flight 111, which crashed off Halifax, Nova Scotia, in 1998, and Valujet Flight 592, which plunged into the Florida Everglades in 1996.
