Articles 28(6) and 37(2)

SCHEDULE 4 Aircraft equipment

1.—(1) Every aircraft of a description specified in the first column of the Table in paragraph 4 which must carry equipment specified in this Schedule must be provided, if flying in the circumstances specified in the second column of the said Table, with adequate equipment.

(2) For the purpose of this paragraph the expression ‘adequate equipment’ means, subject to sub-paragraphs (3) and (4), the scales of equipment respectively indicated in the third column of that Table.

(3) If the aircraft is flying in a combination of such circumstances, the scales of equipment are not on that account required to be duplicated.

(4) Equipment carried in an aircraft that is necessary for the airworthiness of the aircraft is to be taken into account in determining whether this Schedule is complied with for that aircraft.

2.—(1) For the purposes of the Table in paragraph 4 flying time in relation to a helicopter or gyroplane is to be calculated on the assumption that it is flying in still air at the speed specified in the relevant flight manual as the speed for compliance with regulations governing flights over water.

(2) In this Schedule ‘day’ means the time from half an hour before sunrise until half an hour after sunset (both times exclusive), sunset and sunrise being determined at surface level.

3.  The following items of equipment are not required to be of a type approved by EASA or the CAA—

(a) the equipment referred to in Scale A(2);

(b) first aid equipment and handbook, referred to in Scale A(3);
