If a dispatcher presented me with a flight plan that had a course depicted like this one right through the centre of severe to extreme weather, I and no one I work with would dream of accepting it - so how was their flight plan created? Do they have a qualified flight dispatch department? If this is accurately portrayed why would the planners have thought it acceptable to file a course through an area of very heavy weather? Why should a pilot have to get airborne on a route that was clearly not going to work, and then have to start "negotiating"?
