The use of the laser dazzler technology on commercial aircraft is stupid. It is not online yet with the vast majority of military equipment, while a much cheaper and simpler missile warning receiver/flare dispenser would be just as effective.
It’s not as if the flares would be going off every other takeoff, and the dispenser system is proven, reliable, and requires much less maintenance than slewing IR video cameras and slaved IR lasers.
Additionally, you are adding ordinance to a civilian airliner. That adds a hazard element to processing aircraft at the ramp.
Does the flare system handle multiple incoming missiles? I know it can pop out a number of flares (heat sources).
