15. (Refer to Figure 34.) 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 -- --

Empty Weight:
- Weight: 1,350 lbs
- Moment/1000: 51.5
- Moment: 1,350×51.5=69,525 lb-in

Pilot and Front Passenger:
- Weight: 380 lbs
- Arm: 85 in (assumed from standard values)
- Moment: 80×85=32,300 lb-in

Fuel (48 gallons):
- Weight: 48×6 = 288 lbs
- Arm: 75 in (assumed from standard values)
- Moment: 288×75=21,600 lb-in

Oil (8 qt):
- Weight: 15 lbs
- Moment/1000: -0.2
- Moment: -200 lb-in

Total Weight and Moment:
- Total Weight: 1,350+380+288+15 = 2,033 lbs
- Total Moment: 69,525+32,300+21,600−200 = 123,225 lb-in

Moment/1000: 123,225/1,000 = 123.2

Aircraft Category:
- Using Figure 34, we compare the calculated moment/1000 value with the allowable limits for normal and utility categories.
- For a total weight of 2,033 lbs and a moment/1000 of 123.2, we check if this falls within the normal or utility category on the provided envelope.
