I always wonder how many "backup" approach charts and airport diagrams airline pilots have in case the plane has to divert. I imagine a few possibilities:
- There are no approach charts in the cockpit. The only ones the pilots have are those with the flight plan: the departure, destination and any alternates they picked along the route. If the plane must land somewhere else, the pilots will ask ATC to guide them in.
- All of the fleet's destinations are available in the cockpit. If the plane diverts to any one of these airports, it is likely that there will be a ground crew to serve the passengers.
- Every airport that can accommodate the size of the airplane is available, irrespective of whether it is a destination of one of the airline's routes.
- Every airport within the operation area, no matter how big or small, is available.
I imagine with more airlines using Electronic Flight Bags, this would be a non-issue as one can easily load all available charts in the world onto the tablet, and updating them is trivial. Still I am interested in knowing what airlines typically do.
