The weight doe...its kind of a combination of both.<br /><br />The weight does have to be balanced very carefully in an aircraft. Obviously the smaller the aircraft the more it matters.<br /><br />When My OH flies his Cessna he has to manually caluculate the weight of the fuel , passengers luggae etc and work out what ( or who to put where) to balance things out<br /><br />Airlines use a standard avergae weight for passengers , but its also the fuel and the cargo that they have to consider. Again most airlines have to claculte this for every individual trip. it is one of the reasons that doors close before flight and they won't let late passengers on , it screws up their figure ( they are not just trying to piss you off)<br /><br />budget airlines like easy jet , that rely on a tight turnaround use simplified load sheets , which cut down on the calculations needed and thus the turnaround time<br /><br />its all explained here<br /><br />http://www.pprune.org/passengers-slf-self-loading-freight/366421-ryanair-weight-balance-issues.htmlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-28919367.post-60825575490898036372011-06-07T08:05:52.420+00:002011-06-07T08:05:52.420+00:00There are many calculations that should be perform...There are many calculations that should be performed before any aircraft takes off. Two critical factors are for 'weight' & for 'balance'. They apply equally to a light aircraft and to an Airbus 380, although the numbers will be a lot different.<br /><br />Every aircraft will have a Maximum Take Off Weight and might also have a Maximum Landing Weight, depending upon things like the departure & destination elevation, temperature, atmospheric conditions, runway length available etc. This weight must not be exceeded, so it might mean a trade-off between fuel, freight & passengers.<br /><br />It is also important that the centre of gravity (balance) sits within defined fore & aft limits, otherwise it could be impossible to control the aircraft during all phases of flight. So, even if the weight is within limits, you might have to distribute it appropriately to ensure balance.<br /><br />Then again, it's Ryanair, so the laws of physics might have been set aside in favour of the dismal science.<br /><br />Ray.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-28919367.post-39689919646666990982011-06-06T18:20:24.789+00:002011-06-06T18:20:24.789+00:00Self loading ballast is easier to arrange than bag...Self loading ballast is easier to arrange than baggage, I believe it also allows them to carry less fuel (which is pumped to various tanks to maintain the Centre of Gravity) which means they can fly lighter, using less fuel, but still charge the ballast the same.TonyFhttps://www.blogger.com/profile/14356306581977054156noreply@blogger.comtag:blogger.com,1999:blog-28919367.post-1659121998086642372011-06-05T22:36:08.788+00:002011-06-05T22:36:08.788+00:00What Dafydd said.
