FAA Private Pilot Test Prep

Correct answer: C. 210 pounds less and the aircraft is aft of the limits. First calculate the burn of fuel- 35 gallons at 6 pounds per gallon = 210 pounds less. Now look at figure 33 under the fuel numbers: find 35 gallons which is 210 pounds which will change the CG by 158 according to the chart. Subtract the weight from the original weight 2890- 210= 2680. Then subtract the moment of 158 from the original moment of 2452 equals 2294. Now on figure 34 find the new weight of 2680. Look at the two moment numbers for that weight. The first number is the forward GC the second is aft CG. The aft CG for this weight is 2287, our number is now 2294, which mean we are now aft of the acceptable aft CG.
