Traffic Load is the total mass of passengers, baggage, cargo (or freight), including any non-revenue load (Flight crew members are not part of the Traffic Load).

For this question, the Traffic Load consists of the passengers, their baggage (62 items - it doesn't say the type of flight, so use "All other"), non-revenue load (575 kg) and cargo load (1800 kg + 1500 kg + 500 kg = 3800 kg).

According to the annex, the standard mass values for the passengers and their baggage of an aircraft having more than 30 passenger seating capacity, are:

• All Adults: 84 kg
• Children: 35 kg
• Infants: (ages less than 2 years) using the same seat as their parents then their weight is not counted.
• Baggage: 13 kg

Therefore, the Traffic Load will be: Traffic Load = 105 Adults (70 Male Passengers + 35 Female Passengers) + 3 Infants on their own seats (count as children) + 62 Baggage items + Non-revenue load + Cargo load

• 105 Adults = 105 x 84 kg = 8820 kg
• 3 Infants on their own seats = 3 x 35 kg = 105 kg
• 62 baggage items = 62 x 13 kg = 806 kg
• Non-revenue load = 575 kg
• Cargo load = 3800 kg

Traffic load = 8820 kg + 105 kg + 806 kg + 575 kg + 3800 kg = 14 106 kg.
