197 pounds under allowable gross weight; CG 83.6 inches aft of datum.

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.

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.

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.

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.

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. -- ? -- ?

75.4 pound-inches.

Determine the aircraft loaded moment and the aircraft 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.

Calculate the moment of the airplane and determine which category is applicable. 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.

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.

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

CG 83.4, within limits.

GIVEN: WEIGHT (LB) -- ARM (IN) -- MOMENT (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.

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.

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?

The CG moves forward approximately 3 inches.

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

Unusable fuel and undrainable oil.

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.

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
