December 17, 201510 yr Okay i think we can add using AES as a possible cause of this, i never had this issue before until when i finally configured AES to be used with the T7, ever since then, every time after engine start (even if i didnt use AES services at all or i start at an airport that doesnt use AES like default) i would get this message. What i do is go back to the perf init page after start, make a manual fuel entry (any number will do) then delete that manual entry, it will force the FMC to read the calculated fuel and you should be set from there. Its just one possible clue though Hi guys..... I know this is an old post but I seem to be having a similar issue..... I've just completed the 1.5 Tutorial without a hitch other than an oom at landing... Reastarted computer today and setting up a flight from KSFO to KIAD. For flightplanning I used Online flight Planner. I have used this before and seems to calculate the fuel pretty close.... The total fuel recommended is 112972 lbs for about 6-7 hours of flight time So, under fs actions I selected that amount and picked a random payload. Bingo... Insufficient fuel.... I check progress and it showed 0 at arrival in KIAD. I kept upping the fuel and re-setting zero fuel weight and everything else as well as re-entering the complete flight plan runway to runway... no go. So i set long range wich places it at 100%..... Still insufficient fuel and zero fuel at KIAD Reserves I tried 7.0, 15.1 both used on tutorials... Dont know what it is and then I saw this older post... All i have running is GSX but had not used the features.... Any clues... Being an old original post hopefully some of you figured this out... Thanks kindly and to the skies... Will Charles....

December 17, 201510 yr Will, Did you verify the total length of your route on the PROG page after you activated it? KSFO to KIAD should be about 2150 nautical miles, give or take. I am wondering if one of the waypoints in your route might have been misspelled or mid-entered, and actually located halfway around the world. I have made that mistake before. I was planning a flight from Detroit to Miami, in the 737 NGX, and accidentally transposed two letters in a waypoint name in my route. It was a legitimate waypoint - but located in Central Asia! I couldn't figure out why I was getting insufficient fuel warnings until I realized that my total trip distance in the FMS was showing 9,500 miles, instead of the expected 980 miles. This could also happen if the online flight planner you utilized is based on current (Dec 2015), Nav data, but you have the older original Nav database in your 777. It is possible that a waypoint name that is now located in US airspace, was once located elsewhere.

December 17, 201510 yr Commercial Member For flightplanning I used Online flight Planner. I have used this before and seems to calculate the fuel pretty close.... Which one? Depending on the flight planner, it might not be at all accurate. Reserves I tried 7.0, 15.1 both used on tutorials... Values like these are flight-specific - they were calculated for those flights specifically, and will change for any other route, day and weather picture. All i have running is GSX but had not used the features.... No weather programs? SFO to IAD is an eastbound trip, which means that it's wind aided on most days. The planner might have assumed you'd have a tailwind and given you less fuel than you'd need if you weren't using weather (and therefore had no tailwind to shorten the flight time). Kyle Rodgers

ASN running in background here is animage of flight olan with waypoints fuel and a map.. http://fsfiles.org/flightsimshotsv2/image/73n Nothing weird in flight plan... The thing is I just flew from KIAD to EDDM which is a longer flight on 3/4 of a tank per PMDG 777 Tut 1.5 and for this flight I went ahead and topped off the feul tanks just to go to extremes... Still 0 a KIAD. Now I now given any condition except a leaking tank that the 777 will reach KIAD from KSFO given the worst head wind on a full fuel load.... Something is wrong and I dont know what it is.... As mentioned before.... Identical backround addons running for both the KIAD-EDDM from the tutorial as the KSFO-KIAD. The only thing was that I couldnt program the J28 route so I went from the SID direct to the OBH waypoint.... Let me verify the DU with the path on it and see if it takes a odd spike and will get back...... Will Charles Which one? Depending on the flight planner, it might not be at all accurate.

December 17, 201510 yr No doubt the FP from the planning tool is legitimate, but the important thing is to see what the FMS is showing as the total distance to your destination after you enter it. If it is not approximately 2200-2300 NM, something is wrong in the way the FMS is interpreting your route.

December 17, 201510 yr Did you really load the fuel or just changed the number in the perf page? Rob "Sponge" SzymanskaOwner of: PMDG 737/747/777/MD11/J41. LD 767. Aerosoft Airbus X Extended. Majestic Dash 8 Q400. And many more. Vatsim Hours: 1000+
December 17, 201510 yr Commercial Member Please see attached image link Can't. Filtered web traffic for being "peer to peer," apparently. The day job's web filtering is like a paranoid nanny. Either way, to be honest, if you got 0 at IAD for an eastbound flight, your route string was either interpreted poorly (especially possible if you used a site to create a route file for you), or something else you did caused it, like loading a panel state for a pre-service pack version of the plane, or not clearing a manual entry of fuel on the PERF INIT page. If you set a value in there, it doesn't matter how much fuel is in the tanks, it will take your word for it. In Tutorial #1.5, we used a manual entry in that box because we were setting the plane up while it was being fueled. This was then removed later to ensure the aircraft was using how much fuel it thought was in the tanks. If your aircraft is already fueled, then there's no reason to enter anything in that box.

December 17, 201510 yr The only thing was that I couldnt program the J28 route so I went from the SID direct to the OBH waypoint....I don't see J28 in your generated route. The airway from LIN to OBH is J84. In any case, it is essential in troubleshooting this problem to load the route into your FMS, and then check the total distance to your destination from your starting position on the PROG page. The only reason that the FMS would give you zero fuel at IAD even with full tanks, is if it thinks your total trip distance is much longer than the actual 2200 NM from SFO to IAD, OR (perhaps) due to a corrupt installation of the aircraft, or a bad saved panel state. You said it worked well on the tutorial flight, so I would think your installation is OK. [edit] Just noticed Kyle's response - as he mentioned, having an incorrect MANUAL fuel entry could also cause the problem.

However, As far as fuel loading, I tried with the default c& d panel state. The issue I believe is the LIN waypoint Still working on it but I believe as you mentioned.... There is another LIN out there and it sure aint in California! My vectored route from LIN to obh was over 5 thousand miles.... I believe coast to coast is about 3000 give or take.,.. I will confirm it it after awhile and let you... As far as the fuel loading, I do have that down.but cant count on some of the waypoints not having duplicates worldwide... Will get back...

December 17, 201510 yr Commercial Member There is another LIN out there and it sure aint in California! My vectored route from LIN to obh was over 5 thousand miles.... Bingo. This is why I asked what the route was, and suspected an error in it. Sounds like the wrong LIN was selected. Kyle Rodgers
December 21, 201510 yr Thanks Guys... All is well...... Had a wonderful flight and landing! Guillermo Schleimer
