March 10, 200521 yr Just wondering when flying a long trip, say from Toronto to Vancouver I at cruise level get a message from my FMC saying "insufficiant fuel". There is enough fuel on board. I use the fuel calculator and am using FS Nav for to plan the flight. This message remains until just before the TOD, then it disappears. Am I doing something wrong? BGPS
March 10, 200521 yr Hi,Have a look what value you entered in the FMC for reserv fuel, if that value is greater than what you have when you land I belive you will get this warning.
March 11, 200521 yr Author Thanks...I have always used 4.0 as my reserve. Is there a standard that is normally used for the reserve?BGPS
March 11, 200521 yr I belive you'll find that information in the PMDG documentation, I usually use 1000 kg as my reserves.Cheers,
March 17, 200521 yr Any change in your headwind meaning a stronger one i had done that exact flight and there was strong headwinds you needed to board extra fuel.Just a thought!
March 17, 200521 yr Yes - strange things happen when you change the sim rate or pause the sim. The fuel prediction seems to be based on real time, not sim time. It's particularly noticable after you've paused the sim for some time (ie fuel flow rate = 0 ). The FMC then predicts that you'll be able to land with as much fuel in your tanks as you currently have - even if you're 1000 nm from destination. This slowly gets corrected as you fly on at normal sim rate.Ian Ian Box
March 19, 200521 yr Funny you mentioned about fuel consumption and sim rate for I had similar problems but not with the PMDG for I don't use the FMC and fly via manually steering with autopilot (don't ask... I'm just a crazy flightsimmer!:)) I did have fuel IMBALANCE when using the PSS Airbuses and recently, flew the POSKY 747-400 and noticed a fuel imbalance of 10,000 lbs (well above acceptable limits as far as I know). Both times, I was simming at a rate of either 8x (for PSS) or 16X for the POSKY. But I haven't noticed an ACTUAL fuel imbalance in the fuel tanks or fuel running out too soon when running the PMDG 737NG at accelerated sim rates (typicall I use 8X).John I love flying my "iddy biddy Jumbo" CPU: Intel Core 2 Duo E8400, socket 775/3GHz/1333MHz bus/6MB cache MOBO: Asus P5E3 Deluxe WiFi-AP@n/Intel X38 chipset RAM: 4GB Kingston HyperX 1333MHz. rated 7-7-7-20, matched pair (2 x 2GB) GRAPHICS: Sapphire Radeon 5770HD 1GB (w/ fan) MONITOR: Samsung 24", 2494HM LCD wide-screen 1920x1080 SOUND: SoundBlaster Audigy 2 ZS HARD DRIVES: 1xWestern Digital WD1600JD SATA 160GB (primary/Windows XP and system boot drive) 1xWestern Digital WD3200AAJS SATA2 320GB (secondary/Flight Simulator 2004 running off WinXP Pro 32-bit, games video editing drive) 1xWestern Digital 500GB Black series SATA2 (Windows 7 64-bit: FSX is running off Win7; Windows XP Professional 32-bit) CASE: Antec Sonata III 500W OS: Windows 7 Professional 64-bit for FSX; Windows XP Pro 32-bit for other things.
