From Aviation Week Bulletin:
The NTSB met yesterday in its Washington conference center to explore the safety ramifications of "glass cockpits" in small general aviation aircraft. The Safety Board presented an internal study on whether electronic flight instruments in GA cockpits have had any impact on safety statistics. The study showed that the overall accident rate for glass cockpit light airplanes was lower than that of conventionally equipped aircraft but the rate of accidents with fatal outcomes was higher.
The report further showed that pilots of aircraft equipped with electronic Primary Flight Displays involved in accidents were older, had more flying hours, were more likely to hold Instrument ratings and be flying in IMC, and at the time of the accident, likely were flying a longer range mission than accident pilots flying airplanes with round dial instruments.
For those with long memories, the study nearly perfectly reflects the results of previous comparisons of single- and multiengine aircraft accidents, with the more capable multiengine aircraft having a lower accident rate but a higher rate of accidents with a fatal outcome.
The release of the study was followed by the usual NTSB dialog, raising issues of training, standardization of display formats, failure modes, etc.
When it came time to pass recommendations, the session foundered on one that could be interpreted as requiring the FAA to endorse or certify pilots for not only aircraft category, class and type, but also for aircraft model, electronic Primary Flight Display model (if so equipped) and the software version. Vice Chairman Christopher A. Hart objected to the implication, which was hastily reworded by the staff to eliminate recommending equipment-specific initial and recurrent training for glass cockpits.
