December 28, 201114 yr Hi everyone,I had a look on here but couldn't find this answer.Obviously there is a maximum landing weight, but is there a maximum amount of fuel you can land with?The maximum landing weight could be made up of a different balance of fuel and payload but I would think they wouldn't want to land with a lot of fuel left for safety reasons, also considering the extra expense of flying a heavy plane.Thanks.

December 28, 201114 yr It´s up to you to (if you haven´t a fuel program, like Topcat or Vroute flightplan) to check you don´t have to much fuel when landing.If the ac is overloaded when you depature, there will be RED text in the CDU.Have a look in progress page what theoretical fuel you should have left when reaching your destination.You´ll have to have done all your preflight in CDU first. If you see that you have 10 000 kg then justchange the fuel amount before departure so it says some 3000-4000 kg when reaching your destination./ Leffe Leif A Mikkelsen **********************
December 28, 201114 yr Author Thanks for that.I usually plan to land with about 3,000kg fuel.I was just wondering if there is a rule that states a maximum I can land with. Maybe airlines set one or Boeing has. Brett Williamson
December 29, 201114 yr As long as you are below MTOW you are fine. Obviously you wouldnt want to carry more than you have to normally, but there are sometimes reasons to do so. For example lets say the fuel in your destination airport is expensive. Smart airline planning software will then tell you how much fuel to take with you ("tankering") so you dont need to buy expensive fuel in an outstation. If the price is high enough, you may very well end up lading with 8-10 tonnes of fuel, and leaving again without buying a drop more at the airport.Obviously it can also happen the other way and if you flew in to somewhere with dirt cheap fuel, your airline might want you to "fill er up" until you are limited, and to take home as much as you can. --Peter Fabian
December 29, 201114 yr Performance and safety wise the only thing that counts is the Maximum Landing Weight. As long as you are below that it's OK. Obviously the greater your payload (passengers & cargo), the lower the amount of fuel you can carry on top of that. Conversely the lower your payload, the more fuel you can carry on landing.From an airline's point of view fuel is cargo that they don't get paid for, so unless you are tankering (as explained in the post above) having less fuel is better, but that is an economic consideration. A lighter plane has a lower stall speed (and thus VREF) and will be easier to stop, but also has less fuel reserves for a go-around or possible diversion, so the safety benefits of landing with less fuel are debatable.John-Alan Pascoe John-Alan Pascoe

This varies depending on how likley things like delays due to weather or traffic, diversions due to weather concerns, distance to suitable alternates etc.Trent Hopkinson Trent Hopkinson, 2015 Crewmember of www.mangrove.com.au WorldFlight sim Youtube channel www.youtube.com/user/musicalaviator
