Review 7, Weight and Balance

(Refer to Figure 60.) How should the 500-pound weight be shifted to balance the plank on the fulcrum?

1 inch to the left.

(Refer to Figure 34.) What is the maximum amount of baggage that may be loaded aboard the airplane for the CG to remain within the moment envelope? WEIGHT (LB) MOM/1000 Empty weight 1,350 51.5 Pilot and front passenger 250 -- Rear passengers 400 -- Baggage -- -- Fuel, 30 gal -- -- Oil, 8 qt -- -0.2

105 pounds.

If an aircraft is loaded 90 pounds over maximum certificated gross weight and fuel (gasoline) is drained to bring the aircraft weight within limits, how much fuel should be drained?

15 gallons.

An aircraft is loaded 110 pounds over maximum certificated gross weight. If fuel (gasoline) is drained to bring the aircraft weight within limits, how much fuel should be drained?

18.4 gallons.

(Refer to Figures 32 and 33.) Determine if the airplane weight and balance is within limits. Front seat occupants 340 lb Rear seat occupants 295 lb Fuel (main wing tanks) 44 gal Baggage 56 lb

20 pounds overweight, CG within limits.

(Refer to figure 61.) If 50 pounds of weight is located at point X and 100 pounds at point Z, how much weight must be located at point Y to balance the plank?

300 pounds.

(Refer to Figure 34.) What is the maximum amount of fuel that may be aboard the airplane on takeoff if loaded as follows? WEIGHT (LB) MOM/1000 Empty weight 1,350 51.5 Pilot and front passenger 340 -- Rear passengers 310 -- Baggage 45 -- Oil, 8 qt -- --

40 gallons.

(Refer to Figures 32 and 33.) What is the maximum amount of baggage that can be carried when the airplane is loaded as follows? Front seat occupants 387 lb Rear seat occupants 293 lb Fuel 35 gal

45 pounds.

(Refer to Figure 34.) Determine the moment with the following data: WEIGHT (LB) MOM/1000 Empty weight 1,350 51.5 Pilot and front passenger 340 -- Fuel (std tanks) Capacity -- Oil, 8 qt -- --

74.9 pound-inches.

category. WEIGHT (LB) MOM/1000 Empty weight 1,350 51.5 Pilot and front passenger 380 -- Fuel, 48 gal 288 -- Oil, 8 qt -- --

79.2, normal category.

WEIGHT (LB) MOM/1000 Empty weight 1,350 51.5 Pilot and front passenger 310 -- Rear passengers 96 -- Fuel, 38 gal -- -- Oil, 8 qt -- -0.2

80.8, utility category.

(Refer to Figures 32 and 33.) With the airplane loaded as follows, what action can be taken to balance the airplane? Front seat occupants 411 lb Rear seat occupants 100 lb Main wing tanks 44 gal

Add a 100-pound weight to the baggage compartment.

(Refer to Figures 32 and 33.) Calculate the weight and balance and determine if the CG and the weight of the airplane are within limits. Front seat occupants 350 lb Rear seat occupants 325 lb Baggage 27 lb Fuel 35 gal View Figures

CG 83.4, within limits.

GIVEN: WEIGHT ARM MOMENT (LB) (IN) (LB-IN) Empty weight 1,495.0 101.4 151,593.0 Pilot and passengers 380.0 64.0 -- Fuel (30 gal usable-no reserve) -- 96.0 -- The CG is located how far aft of datum?

CG 94.01.

(Refer to Figures 32 and 33.) Which action can adjust the airplane's weight to maximum gross weight and the CG within limits for takeoff? Front seat occupants 425 lb Rear seat occupants 300 lb Fuel, main tanks 44 gal

Drain 9 gallons of fuel.

(Refer to Figure 67.) What effect does a 30-gallon fuel burn have on the weight and balance if the airplane weighed 2,784 pounds and the MOM/100 was 2,222 at takeoff?

Moment will decrease to 2,087 lbs-in.

(Refer to Figures 32 and 33.) Upon landing, the front passenger (180 pounds) departs the airplane. A rear passenger (204 pounds) moves to the front passenger position. What effect does this have on the CG if the airplane weighed 2,690 pounds and the MOM/100 was 2,260 just prior to the passenger transfer? View Figures

The CG moves forward approximately 3 inches.

Which items are included in the empty weight of an aircraft?

Unusable fuel and undrainable oil.

(Refer to Figures 32 and 33.) What effect does a 35-gallon fuel burn (main tanks) have on the weight and balance if the airplane weighed 2,890 pounds and the MOM/100 was 2,452 at takeoff?

Weight is reduced by 210 pounds and the CG is aft of limits.

(Refer to Figures 32 and 33.) Determine if the airplane weight and balance is within limits. Front seat occupants 415 lb Rear seat occupants 110 lb Fuel, main tanks 44 gal Fuel, aux. tanks 19 gal Baggage 32 lb View Figures

Weight within limits, CG out of limits.
