(No. 42 of 1921.) Switzerland ; Air Navigation on and above Swiss Waters ; Geneva Customs Aerodrome 1. REGULATIONS FOR CIVIL FLYING (See also Notice to Airmen No. 117 of 1920.) The following Regulations govening Aerial Navigation on and above Swiss waters have been issued by the Swiss Federal Council :— A. Flight above the water (1) Aircraft flying above water must not approach within 200 metres (220 yards) of steamers and large motor-boats carrying passengers. Flight above these watercraft at an altitude of less than 200 metres (660 feet) is likewise pro- hibited. (2) Aircraft flying at an altitude of less than 200 metres may not cross the path of such watercraft at a distance of less than 300 metres (330 yards). As a general rule aircraft should pass behind watercraft at a distance of at least 200 metres. (3) Aircraft must not manoeuvre in company with these watercraft or carry out turns above them. All acrobatic flight above and within a radius of 1 km. (1,100 yards) of these watercraft is prohibited. B. Navigation on the water. (1) Hydro-aeroplanes may only navigate at night on the lakes and navigable waterways on condition that they are provided with navigation lights (the same as for motor- boats). (2) Hydro-aeroplanes must, moreover, observe the following rules :— (a) A hydro-aeroplane must keep out of the way of all watercraft, of no matter what category, which it may encounter on its course. If for any reason a hydro-aeroplane is incapable of manoeuvring, and if it is in danger on account of the proximity of a large watercraft, it must notify the latter by means of the alarm signal (seven short blasts in rapid succession repeated several times on a fog horn). (b) Watercraft may only be passed or crossed on the right side at a minimum distance of 50 metres (55 yards) and at a speed entailing neither danger nor difficulty to the watercraft. Passing on the left side is only permitted if rendered "hecessary by the proximity of the shore or by some other cause. (c) If the path of a watercraft and that of a hydro-aeroplane cross at right angles or almo?t at right angles, the hydro- aeroplane shall manoeuvre so as to pass behind the water- craft. (d) A hydro-aeroplane in distress shall ask for assistance by means of the signal of distress (seven prolonged blasts in rapid succession repeated several times on a fog horn, and at night, in addition, a rapid succession of flashes made with the navigation lights). C. Departure and arrival of hydro-aeroplanes (1) Departure and arrival may only take place if the space in the direction of departure or arrival is free, and shall in no case take place in the direction of departure and arrival of steamers or large motor-boats carrying passengers. For departure, there must be a sufficient free area of water for the hydro-aeroplane to take off and attain a sufficient altitude and speed to permit it to avoid all ob- structions. During departure or arrival no watercraft shall cross the path or crowd upon the course of a hydro-aeroplane. (2) At night, departure or arrival of hydro-aeroplanes will only be permitted on certain areas of water marked by lights or closed to navigation by surface vessels. (3) In case of fog on the water, taking off or alighting on the lakes and navigable waterways is prohibited. Exception to this rule is made in the case of aircraft compelled to alight in emergency." (4) The areas of waters to be marked with lights will be designated and the slipways for use of hydro-aeroplanes will be determined by the Cantonal Authorities in conjunction with the local authorities and approved air navigation companies. In case of disagreement between the parties, the decision of the Railway Department shall be final. 2.
