Idea: deplane by row. Each row leaves when a light in that row turns on. An algorithm decides when to turn them on based on several factors: keeping large groups together, expected speed of deplaning (eg. elderly may be slower), current occupancy of the aisle. Advantage: should be very fast, easy to follow, groups stay together.
