Hay to all,I am an Italian simmer, and my English is poor! I received this gift frommy son. I do not in which way I can refuelling this plane. From FS, I notes that for all 737, the max. LB are 46062.5!!!!! This isnot possible as the extimate ranges are different, so I feel that should bea different way to do it. Any way, INSUFFICIEN FUEL, appears every time.I need help. I have been used since now only MADDOG. Regards,Luigi BrambillaPS: If someone speaks Italian.......

The insufficient fuel message on the FMS appears if it thinks you don't have enough fuel. It includes your reserves that you put into the FMS. Check your route in the FMS to make sure it has no surpises like a fix on the other side of the world.

Thank you Dan. No problems about fix. I checked several Vole Plane, about istances.This is not the problem. But maybe you can let me know which way are you usingto refuelling. By FS or........ ByeGigi

I use Topcat its good load of infomation as wellanother good one is by Ross Carlson fuel planner on avsim i think.Richard

The 737NG for 2004 is refueled with the payload/fuel dialog box you show a picture of. Click on modify fuel (carburante) button and enter the amount of fuel you want in the wing/main tanks. The wing tanks should be full before adding fuel to the center main tank.Maybe I don't understand the question.

Hi Luigi,What numbers are you putting into the "RESERVES" and "COST INDEX" on the "PERF INIT" page?

Reserve is 55 and cost 50

Reserve is 55 and cost 50

Fuel reserves is the MINIMUM amount of fuel you ever want to have in the tank. So, if you have 20,000lbs of fuel in total, 3,000lbs of which is reserves, you only have 17,000lbs to use.The "RESERVES" field asks for the number of tons. So if you input 55, the FMC thinks you want to land with a minimum of 55,000lbs of fuel! Usually, you want to land with a minimum of around 3,000lbs of fuel, so try putting "3.0" into the "RESERVES" field.
