When computing the mass of passengers and baggage for an aircraft with 20 seats or more:

1. Standard masses of male and female in Table 1 are applicable
2. If there are thirty seats or more, the 'All Adult' mass values in Table 1 may be used as an alternative
3. Holiday Charter masses apply to Table 1 and Table 3 if the charter is solely intended as an element of a holiday travel package
4. Holiday flights and holiday charters attract the same mass values
