Answer explanation

Refer to figure 34.

Input just the number in the answer box.

Answer explanation

To find the maximum amount of fuel this airplane can carry, add the empty weight (1,350), pilot and front passenger weight (340), rear passengers (310), baggage (45), and oil (15), for a total of 2,060 pounds. (Find the oil weight and moment by consulting Note 2 on Fig. 34. It is 15 lb. and –0.2 moments.) Gross weight maximum on the center of gravity moment envelope chart is 2,300. Thus, 240 lb. of weight (2,300 – 2,060) is available for fuel. Since each gallon of fuel weighs 6 lb., this airplane can carry 40 gallons of fuel (240 ÷ 6 lb. per gallon) if its center of gravity moments do not exceed the limit. Note that long-range tanks were not mentioned; assume they exist.

Compute the moments for each item. The empty weight moment is given as 51.5. Calculate the moment for the pilot and front passenger as 12.8, the rear passengers as 22.5, the fuel as 11.5, the baggage as 4.0, and the oil as –0.2. These total to 102.1, which is within the envelope, so 40 gallons of fuel may be carried.

How should the 500-pound weight be shifted to balance the plank on the fulcrum?

• 1 inch to the left

• 1 inch to the right

• 4.5 inches to the right

• 

Answer explanation

Refer to figure 34.

• 79.2, utility

• 80.8, utility

• 81.2, normal

Answer explanation

First, total the weight to get 1,999 lb. Note that the 38 gal. of fuel weighs 228 lb. (38 gal. × 6 lb./gallon).

Find the moments for the pilot and front seat passenger, rear passengers, and fuel by using the loading graph in Fig. 34. Find the oil weight and moment (15 lb. and –0.2 moments) by consulting Note 2. Note the reference point for 38 gal. of fuel is not depicted correctly. Use the fuel weight of 228 lb. for the calculation. Total the moments as shown in the schedule below.

Now refer to the center of gravity moment envelope. Find the gross weight of 1,999 lb. on the vertical scale, and move horizontally across the chart until intersecting the vertical line that represents the 80.8 moment. Note that a moment of 80.8 lb.-in. falls into the utility category envelope.

Refer to figure 34.

• 69.9 pound inches

• 75.1 pound inches

• 77.6 pound inches

Answer explanation

To find the CG moment/1000, find the moments for each item and total the moments as shown in the schedule below. For the fuel, the loading graph shows the maximum as 38 gal. for standard tanks. Note that the reference point for 38 gal. of fuel is not depicted correctly in the FAA figure. Use the fuel weight of 228 lb. for the calculation (38 gal. × 6 lb. = 228 pounds). Find the oil weight and moment by consulting Note 2 on Fig. 34; it is 15 lb. and –0.2 moments. These total 75.1, so this answer is correct.
