Flight Plan Update implementation

2/26/2014

To update a flight plan,

1. Register a handler in KDS thread to handle updates of moving points from all devices.

Handler handleUpdates(List<MovingPoint> p){

for each p:

check if p is similar to KDS’s prediction

if not {updateFlightPlan(p);}

}

2. In GetLocation Async background task, after getting the data of all moving points, put them into a list of MovingPoint and call KDS.handleUpdates(list of moving points) to handle the updates. This is done repeatedly each 2 seconds because GetLocation is called every 2 seconds.
