    (2) Subject to paragraph (3) for the purpose of calculating the total weight of the aircraft the respective total weights of the passengers and crew together with their hand baggage entered in the load sheet shall be computed from the actual weight of each person and their hand baggage and for that purpose each person and their hand baggage shall be separately weighed.

    (3) The total weights of the passengers and crew together with their hand baggage may, in accordance with paragraphs (4) to (9) and subject to the provisions of paragraphs (13), (14) and (15), be calculated at not less than the appropriate weights shown in Tables 1 or 2 and the load sheet shall bear a notation to that effect.

Table 1

           Passenger Seats Available

           20 or more 30 or more

           Male Female All adult

    (5) Where the total number of passenger seats available is 30 or more, the "all adult" weights in Table 1 may be used for passengers over the age of 12 years.

    (6) For the purpose of Table 1, "holiday charter" means a flight by an aircraft for the carriage of passengers each of whom is carried pursuant to an agreement which provides for carriage by air to a place outside United Kingdom and back from that place, or from another place to United Kingdom (whether or not on the same aircraft) and for accommodation at a place outside United Kingdom.

    (7) Where the total number of passenger seats available on an aircraft is 19 or less the weights in Table 2 are applicable.

    (9) Where an immersion suit is worn or carried by a passenger or crew member, 3kg shall be added to the appropriate weight shown in Table 1 or 2 in each such case.

    (10) Subject to paragraph (11) for the purpose of calculating the total weight of the aircraft the respective total weights of the hold baggage and cargo entered in the load sheet shall be computed from the actual weight of each piece of baggage, cargo or cargo container and for that purpose each piece or container shall be separately weighed.

    (11) In the case of an aircraft where the total number of passenger seats available is 20 or more, the total weights of the hold baggage may, subject to the provisions of paragraphs (13), (14) and (15), be calculated at not less than the weights shown in Table 3 and the load sheet shall bear a notation to that effect.

Table 3

Journey made by aircraft Hold baggage per piece

Domestic 11kg

European 13kg

Intercontinental 15kg

    (12) For the purposes of Table 3:

(a) a journey made by an aircraft shall be treated as domestic if it is confined within an area enclosed by rhumb lines joining successively the following points—

N7200.00 W01000.00 N7200.00 E04500.00

(c) A journey made by an aircraft shall be treated as intercontinental if it is neither domestic nor European.

    (13) If it appears to the person supervising the loading of the aircraft that any of the circumstances described in paragraph (14) arise he shall, if he considers it necessary in the interests of the safety of the aircraft, or if the CAA has so directed in the particular case, require any such person and his hand baggage, passenger or hold baggage, as the case may be, to be weighed for the purpose of the entry to be made in the load sheet.

    (14) The circumstances referred to in paragraph (13) are:

(a) any person and his hand baggage to be carried exceeds the weights set out in Tables 1 or 2; or

(b) where paragraph (8) applies any passenger to be carried exceeds the weights set out in Table 2 as adjusted in accordance with that paragraph; or

(c) any hold baggage to be carried exceeds the weights set out in Table 3.

    (15) If any person and his hand baggage, passenger or any hold baggage has been weighed pursuant to paragraph (13), the weights entered in the load sheet shall take account of the actual weight of that person and his hand baggage, that passenger or that hold baggage, as the case may be, or of the weight determined in accordance with paragraphs (3) or (11), whichever weight shall be the greater.

     ‘the landing distance available' means the distance from the point on the surface of the aerodrome above which the aeroplane can commence its landing, having regard to the obstructions in its approach path, to the nearest point in the direction of landing at which the surface of the aerodrome is incapable of bearing the weight of the aeroplane under normal operating conditions or at which there is an obstacle capable of affecting the safety of the aeroplane;

     ‘the take-off distance available' means either the distance from the point on the surface of the aerodrome at which the aeroplane can commence its take-off run to the nearest obstacle in the direction of take-off projecting above the surface of the aerodrome and capable of affecting the safety of the aeroplane, or one and one half times the take-off run available, whichever is the less;

     ‘the take-off run available' means the distance from the point on the surface of the aerodrome at which the aeroplane can commence its take-off run to the nearest point in the direction of take-off at which the surface of the aerodrome is incapable of bearing the weight of the aeroplane under normal operating conditions.

    (4) For the purposes of Schedules 2 and 3—

(a) the weight of the aircraft at the commencement of the take-off run or of the take-off shall be taken to be its gross weight including everything and everyone carried in or on it at the commencement of the take-off run or of the take-off;

(b) the landing weight of the aircraft shall be taken to be the weight of the aircraft at the estimated time of landing allowing for the weight of the fuel and oil expected to be used on the flight to the aerodrome at which it is intended to land or, any alternate aerodrome, as the case may be;

(c) where any distance referred to in paragraph (3) has been declared in respect of any aerodrome by the authority responsible for regulating air navigation over the territory of the Contracting State in which the aerodrome is situated, and in the case of an aerodrome in the United Kingdom, notified, that distance shall be deemed to be the relevant distance.

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations consolidate the Air Navigation (General) Regulations 1993, as amended by the Air Navigation (General) (Amendment) Regulations 1995, 1997, 2000, 2002 and 2003, the Air Navigation (General) (Second Amendment) Regulations 1999, and the Air Navigation (General) (Amendment) (No. 2) Regulations 2003. Those Regulations are revoked.

In addition to minor, drafting amendments the Regulations make the following changes of substance—

    (1) Under Article 44(1) of the Air Navigation Order 2005 aeroplanes registered in the United Kingdom and flying for the purposes of public transport must comply with JAR-OPS 1 but the CAA may grant a permission under Article 44(5) in respect of such aeroplanes, authorising them to comply with the applicable provisions of Schedule 2 of these Regulations instead. Aeroplanes to which the CAA grants a permission under article 44(5) of the Air Navigation Order 2005 are required to comply with Schedule 2. This comprises public transport aeroplanes designated as aeroplanes of performance groups A, B, C, D, E, F, X and Z, the latter designation being intended for aeroplanes with no performance group classification in their certificates of airworthiness. (Regulation 5 and Schedule 2).

    (2) Regulations 7 to 12 of the Air Navigation (General) Regulations 1993, which specified prescribed performance criteria, have been transcribed to Schedule 2. The Schedule to the Air Navigation (General) Regulations 1993 has also been transcribed to, and is now paragraph 7 of Schedule 2.

    (3) Regulations 19, 20 and 21 of the Air Navigation (General) Regulations 1993 have been transcribed into Schedule 3 of these Regulations. Schedule 3 applies to helicopters, to which article 45(1) of the Air Navigation Order 2005 applies. This comprises public transport helicopters carrying out performance class 1, 2 and 3 operations. (Regulation 6 and Schedule 3)

    (4) The Regulations prescribe the capability and function for Mode S elementary surveillance and Mode S enhanced surveillance under paragraph 3 of Schedule 5 to the Air Navigation Order 2005. (Regulation 15)

    (5) Regulation 14 of the Air Navigation (General) Regulations 1993 (Certificates of Maintenance Review and of Release to Service—issued by maintenance engineers licensed by prescribed countries) has not been replicated in these Regulations.
