Calculation of the Charge

6.—(1) The charge shall be calculated in ECUs according to the following formula—

r = N × U

where

  • r is the charge for the flight, N is the number of service units relating to that flight and U is the appropriate unit rate specified in column 3 of Schedule 2 hereto in relation to the specified airspace through which the flight is made, increased or decreased as the case may be by the same percentage as the relevant national currency has increased or decreased against the ECU as compared with the rate of exchange specified in column 4 of the said Schedule in relation to that airspace.

(2) For the purpose of the preceding paragraph, the number of service units relating to a flight shall be calculated in accordance with the following formula—

N = d × p

where

  • d is the distance factor for the flight in the specified airspace in question and p is the weight factor for the aircraft concerned.

(3) For the purposes of the preceding paragraph—

(a)the distance factor shall be the number of kilometres in the great circle distance between the points specified in paragraph (4) of this regulation minus 20 kilometres for each landing and take-off in the specified airspace in question, divided by 100 and expressed to two places of decimals, and

(b)the weight factor, subject to the provisions of paragraphs (6) and (7) of this regulation, shall be equal to the square root of the quotient obtained by dividing by 50 the number of metric tonnes of the maximum total weight authorised of the aircraft and shall be expressed to two places of decimals.

(4) The points referred to in paragraph (3) of this regulation are—

(a)the aerodrome of departure within the specified airspace in question or, if there is no such aerodrome, the point of entry into that airspace; and

(b)the aerodrome of first destination within the specified airspace in question or, if there is no such aerodrome, the point of exit from that airspace.

(5) For the purposes of the preceding paragraph, the point of entry into the specified airspace in question and the point of exit from that airspace shall be the points at which the lateral limits of the said airspace are crossed by the route described in the flight plan communicated by or on behalf of the operator of the aircraft either to the appropriate air traffic control unit or to the Flow Management Unit of Eurocontrol with any modifications thereto subsequently made or approved by or on behalf of the operator.

(6) Subject to paragraph (7) below, the weight factor for an aircraft of any type shall be calculated by reference to the maximum total weight authorised of the heaviest aircraft of that type.

(7) Where an operator has indicated to Eurocontrol, within the period of one year immediately preceding the flight, the composition of the fleet of aircraft which he operates and which includes two or more aircraft which are different versions of the same type of aircraft, the weight factor shall be calculated by reference to the average of the maximum total weight authorised of all his aircraft of that type so indicated to Eurocontrol.

(8) For the purposes of this regulation the rate of exchange of the ECU to a national currency shall be the average monthly rate of exchange of the ECU to that national currency established by Eurocontrol for the month preceding the month during which the flight takes place.
