G!^ accordance with the directions of the Secretary of State has been made in flying trials that the aircraft is sale for the purpose for which it is intended.^ Periodic Overhaul 5. All passenger aircraft must-be inspected, overhauled and certified as airworthy by competent persons appointed by the owners or users of them, and licensed for the purpose under this schedule, at such times as the Secre tary of State may direct, and such certificate or certificates must be produced to the Secretary of State on demand. 6. Aircraft inspected, overhauled, or certified as provided in the foregoing paragraph may be inspected by authorised representatives of the Secretary of State, and the Secretary of State is entitled under these regulations to cancel or suspend the certificate of airworthiness of any aircraft deemed to be unsafe as a result of such inspection. Examination before each Flight 7. No passenger aircraft carrying passengers shall on any day proceed on any journey unless it has previously been inspected at least once on that day by a competent person licensed for the purpose under this schedule, who shall not be the pilot of the particular machine. 8. If such competent person is satisfied that the aircraft is fit in every way for the flight or flights proposed he shall sign in duplicate a certificate to that effect, which certificate shall be countersigned by another person in the employment of the owner, giving the time and date of such certification. For this purpose the countersignature of the pilot may be accepted. 9. One copy of each certificate will be retained by the owner of the air craft, and the duplicate copy must be carried in the aircraft. 10. The pilot will be responsible for seeing that the aircraft, before com mencing any flight, is, in his opinion, in a satisfactory condition, and does not carry more than the load specified in the certificate of airworthiness, and must sign a certificate to that effect SCHEDULE IV.—Registration and Nationality Marks • I. The registration and nationality marks shall be such as the Secretary of State may direct. 2. The registration and nationality marks shall be affixed in Mack on a white ground in the following manner, and underlined with a black line :— (a) Flying Machines.—The marks shall be painted once on the lower surface of the lower main planes, and once on the upper surface of the top main planes, the top of the letters to be towards the leading edge. They shall also be painted along each side of the fuselage between the main planes and the tail planes. In cases where the machine is not provided with fuselage the marks shall be painted on the nacelle. (6) Airships and Balloons.—In the case of airships the marks shall be painted near the maximum cross section on both sides and on the upper surface equidistant from the letters on the sides. In the case of balloons two marks shall be painted on the maximum horizontal circumference as far as possible from one another. In the case of airships the side marks shall be visible both from the sides and ground. 3. The nationality mark in the case of flying machines and airships shall also be painted on the port and starboard sides of the lower surface of the lowest tail planes or elevators and also on the upper surface of the top tail planes or elevators, whichever is the larger. It shall also be painted on both sides of the rudder, or on the outer sides of the outer rudders if more than one rudder is fitted. In the case of balloons the nationality mark shall be painted on the basket. 4. In the case of flying machines the height of marks on the main planes and tail planes respectively shall be equal to four-fifths of the chord, and in the case of the rudder shall be as large as possible. The height of the marks on the fuselage or nacelle shall be equal to four-fifths of the depth of the narrowest part of that portion of the fuselage or nacelle on which the marks are painted. In the case of airships the nationality mark painted on the tail plane shall be equal in height to four-fifths of the chord of the tail plane and in the case of the rudder shall be as large as possible. The height of the other marks shall be equal to at least one-twelfth of the circumference at the maximum transverse cross-section of the airship. In the case of balloons the height of the nationality mark shall be equal to four-fifths of the height of the basket, and the height of the other marks shall be equal to at least one-twelfth of the circumference of the balloon. In the case of all aircraft the letters of the nationality and registration marks need not exceed 8 ft. in height. 5. The width of the numbers or letters shall be two-thirds of their height and the thickness shall be one-sixth of their height. The numbers or letters shall be painted in plain block type and shall be uniform in shape and size. A space equal to half the width of the numbers or letters shall be left between each number or letter. 6. In the case of underlined letters the thickness of the lines shall be equal to the thickness of the letter. The space between the bottom of the letters and the line shall be equal to the thickness of the line. 7. Where the registration and nationality marks appear together a hyphen of a length equal to that of one of the numbers or letters shall be painted between the nationality mark and registration mark. 8. The registration and nationality marks shall be displayed to the best possible advantage, taking into consideration the constructional features of the aircraft. The marks must be kept clean and visible. SCHEDULE V.—Log Books 1. Log books shall take the form of an aircraft log book, an engine log book, a journey log book, and a signal log book. If more than one engine is fitted a separate log book shall be provided for each engine. 2. Each log book shall be self-contained, but all log books shall be kept together in the aircraft in a waterproof bag of a pattern authorised by the Secretary of State. 3. The log books shall conform in all essentials to the patterns authorised by the Secretary of State, and shall contain such information and particulars as the Secretary of State may direct.

The prohibited areas are more particularly shown in a map issued for the purpose by the Secretary of State. 3. The officer to give the signals and take the action mentioned in section 2 of the Aerial Navigation Act, 1913, shall be a commissioned officer in His Majesty's Naval, Military, or Air Forces. 4. The signals which may be given when an aircraft flies, or attempts to fly, over any of the prohibited areas shall be as follows :— By day : three discharges, at intervals of not less than 10 sees., of a pro jectile showing smoke on bursting. By night : three discharges, at intervals of not less than 10 sees., of a pro jectile showing red stars or red lights. On such signal being given, the aircraft shall immediately land at the nearest practicable spot ; provided that, if it be approaching or flying over any prohibited area, it shall not, in descending, advance further towards or into the area. 6. If an aircraft is unable to land immediately in response to the signal, owing to stress of weather or other unavoidable cause, it shall make the following signal:— By day : show, from the place where they can be most clearly seen front below, a red triangular flag, together with two black balls superimposed vertically one above the other ; By night: wave a white light, at the same time extinguishing the side lights ; and shall, as soon as possible, land at the nearest practicable spot in the United Kingdom. SCHEDULE VII.—Rules as to Lights and Signals and Rules of the Air. Interpretation of Rules In these rules— The word " aircraft " comprises all balloons, whether fixed or free, kites, airships, and flying machines ; The word " balloon ," either fixed or free shall mean an aircraft lighter than air, and having no means of propulsion ; The word " airship " shall mean an aircraft lighter than air, and having means of propulsion ; The word " flying machine " shall mean all aeroplanes, seaplanes, flying boats, or other flying machines heavier than air, and having means of propulsion. The word " visible," when applied to lights, shall mean visible on a dark night with a ciear atmosphere. An airship is " under way " within the meaning of these rules when it i» not made fast to the ground or any object on land or water. The angular limits laid down in these rules shall be determined when the aircraft is in its normal attitude for flying on a rectilinear horizontal course. 1.—RULES AS TO LIGHTS AND SIGNALS. 1. The rules concerning lights shall be complied with in all weathers from sunset to sunrise, and during such time no other lights which may be mis taken for the prescribed navigation lights shall be exhibited. The said prescribed navigation lights must not be dazzling. 2. A flying machine when in the air, or manoeuvring on land or water under its own power, shall carry the following lights :— (a) Forward, a white light, visible in a dihedral angle of 220° bisected by a vertical plane through the line of flight, and of such a character as to be visible at a distance of at least 5 miles ; (6) On the starboard side, a green light, so constructed and fixed as to show an unbroken light between two vertical planes, whose dihedral angle i^ JIO° when measured to the right from dead ahead, and of such a character as to be visible at a distance of at least 3 miles ; (c) On the port side, a red light, so constructed and fixed as to show an unbroken light between two vertical planes whose dihedral angle is no" when measured to the left from dead ahead, and of such a character as to be visible at a distance of at least 3 miles; (d) The said green and red sidelights shall be fitted so that the green light shall not be seen from the port side, nor the red light from the starboard side; (e) At the rear, and as far aft as possible, a white light shining rearwards. and visible in a dihedral angle of 1400 bisected by a vertical plane through the line of flight ; (/) In the case where, in order to fulfil conditions (a) to (e) above, the single light has to be replaced by several lights, the field of visibility of each of these lights should be so limited that in no case can more than one !»• seen at a time. 3. The rules as to the lighting of flying machines shall apply to airships, subject to the following modifications:— (a) All lights shall be doubled, the forward and aft lights vertically, and the side lights horizontally; (b) Both lights of each pair forward and aft shall be visible at the same time. The distance between each light comprising a pair shall not be less than 6 ft. 4. An airship, when being towed, shall carry the lights referred to in rule 3, and in addition those specified in rule 6 for airships not under control. 5. A flying machine, when on the surface of the water and when not under control, that is to say, not able to manoeuvre as required by the regulations for preventing collisions at sea, shall carry two red lights not less than 6 ft. apart in a vertical line one over the other, and of such a character as to be visible all round the horizon at a distance of at least 2 miles. In addition the side lights must be shown if the flying machine is under way. 6. An airship, which from any cause is not under control, or which has voluntarily stopped her engines, shall, in addition to the other specified lights, display conspicuously two red lights, one over the, other approximately in a vertical line, not less than 6 ft. apart and constructed to show a light in all directions and of such a character as to be visible at a distance of at least 2 miles. By day an airship, when being towed, or which from any cause is not under control, shall display conspicuously two black balls or shapes, each 2 ft in diameter, placed one over the other and approximately in a vertical line. An airship moored or under way, but having voluntarily stopped its engines, shall display conspicuously by day a black ball or shape 2 ft. in diameter, and shall be treated by other aircraft as being not under control. 7. A free balloon shall carry one bright white light below the car at a distance of not less than 20 ft., and so constructed as to show an unbroken light in all directions and of such a character as to be visible at a distance of at least 2 miles. 6l0
