Getting close to next patch. As Q8 mentioned, the Preflight menu was a "step back", but I still contend we had to take that step back to take some steps forward. So in the next patch, the following GUI will be avail on the PREFLIGHT tab.
From this GUI, you'll be able to set the start state as usual (via the RESTART button + checkbox state). Also the quick "Plan fuel calculator" for quick fuel calcs is back. For loading fuel, you'll now use a "Aircraft fuel request" panel to add your fuel. You can hit the 'typical' button, which uses a common fuel config for most short hauls...or the "plan fuel" button, which takes its fuel amount from the "plan fuel calculator" ...or finally, you just move the sliders manually. Each of these actions constitutes a 'fuel request'. As fuel is requested, then you will see the amount requested below, along with the estimated time to refuel. If you have the "real time fueling" pref enabled, then this will be on the order of minutes normally, but if that preference is unchecked, then the estimated time will show only a few seconds. To actually add the fuel, you hit the 'start fueling' button. The 'meters' on the right show the requested fuel (red lines) as well as the actual fuel.
The load sheet GUI is used to configure the weight and CG of the aircraft, by adding passengers and cargo and shifting the cargo around. I don't have passenger shifting atm, they're currently 'well balanced' throughout. You can drag a slider to add/remove passengers. There is also a "weight factor" slider, that defaults to one, which represents 'average weights" for humans / baggage"....BUT if you want to overload the plane, or simulate say, a plane full of Sumo wrestlers, then you can up this slider to add some extra "density" to the passenger cabin payload.
There's a pulldown to view the cabin vs. cargo hold. When viewing the cargo hold, there'll be two sliders, one for "additional cargo", which is cargo not related to the passengers, which many airlines do carry...and there'll also be a "bias slider", where you can shift cargo between the front/rear holds to adjust the CG range and get the trim units value. Adjusting the cargo hold loading between front/rear is the preferred way to tweak the CG.
Sorry we had to backtrack a bit before we could get this back in, but hope it helps maintain immersion by not having to go to the default XP menus for fuel and payload.
Down below is what the cargo sliders look like (more or less...this was a few days back and there's been some slight improvements since then)
