If you're looking to Download ForeFlight Passenger on your Chromebook laptop Then read the following guideline.

Passenger is the companion app to ForeFlight Mobile that answers the question “Are we there yet?” Built on ForeFlight’s high-performance map engine, Passenger automatically connects to your pilot’s ForeFlight app and displays the current route so you can monitor your flight’s progress. Passenger also provides helpful flight information like time to destination, expected arrival time, altitude, groundspeed, and magnetic bearing. Any time your pilot makes changes to the route in ForeFlight, Passenger will automatically update the route shown to reflect those changes.
