Annex 1 (Art. 1 para. 2)

Calculation of tonne-kilometres

1 Tonne-kilometres shall be calculated on the basis of the following formula: tonne-kilometres [tkm] = distance [km] x payload [t].

2 Distance means the great circle distance between the aerodrome of departure and the aerodrome of arrival, plus an additional fixed factor of 95 km.

3 Payload means the total mass of conveyed freight, mail and passengers.

4 For the purposes of calculating the payload:

4.1 the number of passengers corresponds to the number of persons on board, excluding crew members;

4.2 aircraft operators may choose to apply either the actual or standard mass for passengers and checked baggage contained in their mass and balance documentation for the relevant flights or a default value of 100 kilograms for each passenger and his/her checked baggage.
