THE LATEST black boxes-which are really bright orange-are better tools for deciphering crash causes. Older data recorders noted some half-dozen flight parameters, such as speed, direction, and altitude over sea level; today’s devices can record more than 100 parameters, including throttle position,altitude over terrain,and outside air temperature. Although most data recorders still use magnetic tape,federal rules may soon call for more reliable solid-state devices. Digital Flight Data Recorder This solid-state device records 25 hours of data.
