According to the average weights table, what is the Summer weight for an adult?

• A. 195
• B. 185
• C. 180
• D. 190

Answer: (B)

Knowing how the average weights table is used in flight planning is key here. The table provides typical occupant weights separated by season so you can account for how weather and clothing affect how much people weigh on average. For an adult in the summer, the standard value is 185 pounds. This reflects lighter clothing and warmer weather, which generally reduces average weight compared to other seasons. This value is what you use when estimating payload or performing weight and balance calculations for summer operations. For example, two adults would contribute 370 pounds to the payload, plus baggage, fuel, etc. The other numbers would correspond to different seasonal assumptions, not the summer figure.
