Incomplete NATS

Recommended Posts

Hello captains,I have 2 questions regarding NATS.1. Concerning the NAT message quoted below, westbound track G. Track G starts at 38N040W. This lies in the middle of the ocean, there is no direct connection to it (check http://www.jetplan.com/tda/west.html , you can see it almost on the bottom-center of the picture). Suppose I'm taking off at Heathrow and I want to fly to the carribean using track G. How would I plan the EGLL-38N040W? Or to put it in another way, how can I get to 38N040W in a "correct" way?2. Sometimes you find an incomplete message when going to the DINS NOTAM system to fetch the current NATS. Today's westbound tracks are a good example:===302018 EGGXZOZX(NAT-1/2 TRACKS FLS 310/390 INCLUSIVEMAY 01/1130Z TO MAY 01/1900ZPART TWO OF TWO PARTS-F DOGAL 55/20 55/30 54/40 51/50 DENDU CYMONEAST LVLS NILWEST LVLS 310 320 330 340 350 360 370 380 390EUR RTS WEST BURAKNAR N142B N148B-G 38/40 36/50 34/60 LAZEYEAST LVLS NILWEST LVLS 310 320 340 380EUR RTS WEST NILNAR NILREMARKS.1.

Sometimes, when you're lucky, they correct the message. Most of the time they don't. This makes it very hard for correct NAT planning.When you go to this site: http://www.jetplan.com/tda/west.html , and click on FINAL, you will find ALL the tracks, including A-E. This site is ALWAYS complete, however, it doesn't give you the text version which is necessary for flight planning, it will only give you a generated picture.My question is, does anybody know more reliable sources for NATS instead of DINS (which provide a textual version)?Thanks for your help,Kind regards,Bart
