When all the data is inputted, you can then "CALC" or set everything and get the aircraft's "Takeoff Weight and CoG (centre of gravity), the one thing I will note is that this Magknight B789 is very good for first timers in for a step introduction to setting up aircraf...
Both performance and stability depend on the location of the center of gravity. Therefore, all flight tests must be conducted with an accurate knowledge of the location of the center of gravity at any one point in time. Structural loads. An analysis that is performed on all the aircraft in ...
is not very high either (15,000kg) as per SimBrief. When you have sorted out your loading, then press "Apply Changes" to set the required loads and weights, which are then detailed as your ZFW (Zero Fuel Weight), Takeoff and Landing Weights with you Centre of Gravity (MAC) percentages...
When you do a "CALC" (Calculation) on the EFB, it gives you your load CG (Centre of Gravity), in this case 26.1% with a TO trim as noted (yellow arrow) of 4.25º, so you need to adjust your trim for Takeoff, it makes sense of course. The fix is to simply adju...
