Those of you who fly OCAS at times may want to take a look at this new free on-line flightplanning tool, which has just been launched with NATS endorsement. Had a brief look myself and seems to offer more guidance and in a more comprehensible form than has been available to date.

might I also suggest that OCAS if you are unsure as to who to call, give London Info a call. If they can't offer you an appropriate service, they will suggest someone who can.
