OCTOBER 13, 1921 NOTICES TO AIRMEN Norway : Customs Aerodromes, Aerial Corridors, Prohibited Areas 1. Customs Aerodromes. (a) By the terms of the provisional agreement relating toAir Navigation between Great Britain and Norway, signed on July 15, 1921, all aircraft entering or leaving" Norwaymust land at, or depart from, either Kjeller (land machines) or Horten (seaplanes).The following particulars of these stations are available :— (ft) KJELLER.—Military and Civil Customs Aerodrome. Position.—Latitude 59° 58' N., longitude n° 3' E. SituatedICJ kms. E.N.E. of Christiania, 1 km. N.W. of the small town of Lillestrom. Description.—The aerodrome is divided by a stream into two sections, the northern section being 400 x 275 yds. and the southern section 600 x 400 yds. During the winter one portion of the aerodrome is kept clear of sno-w. the remainder being left snow-covered for the use of machines fitted with skis. The aerodrome is normally well drained, but is liable to be flooded when the snow melts. The surface is reported to be not very good. The altitude of the aerodrome is 340 ft. The surrounding country is generally hilly, but immediately to the east of the aerodrome there is marshy ground. A wind indicator is displayed from the roof of a hangar on each portion of the aerodrome. Flares are available for night landings. Obstructions.—Northern section.—The approach from the north is rendered difficult by the presence of factory buildings, hangars and a hill 200 ft. high. Southern section.—East side : telephone wires. Accommodation, etc.—Hangars are available on each ground. Petrol and oil are available, and there are good repair facilities. (c) HORTEN.—Naval and Civil Customs Seaplane Station. Position.—Latitude 59° 26' N., longitude io° 30' E. Situated on the western side of Christianiafjord, 56 kms. S.S.W. of Christiania. The station is 2 kms. north of Horten and on the western side of the small peninsula on which stands Karl Johannsvaern Dockyard. Description.—A part of the inner harbour (to the west of the station) which is almost entirely surrounded by low- lying islands, is available for alighting : dimensions (approx.) 1,000 x 1,000 yds. Sheltered water will be found in the fjord, near the station, in practically all weathers. There is a wind indicator on a hangar on the east side of the station. Night landing arrangements.—There are no permanent arrangements for night landing. Two marine lighthouses in the vicinity form a good guide—one on the island of Basto, 6 kms. S.S.E., and the other on the island of Gulholmen, 5 kms. E. of the station. (See map attached.) For the characteristics of these lights, see Admiralty List of Lights and Time Signals. Accommodation, etc.—Hangars, repair facilities, petrol and oil are available. AM?.—Since Horten lies within a prohibited area, it should be noted that it can only be approached by certain corridors, at a maximum height of 200 metres (650 ft. approx.). See para. 3 of this notice and the map attached. 2. Aerial Corridors. No special corridors have at present been laid down for crossing the Norwegian frontier. Aircraft in doing so, however f should not pass within 5 kms. of a Prohibited Area. They should moreover, as far as possible, enter Norway «ast of Faeder Lighthouse (latitude 590 2' N., longitude io° 32' E.) or at Fredrikshald. The further course over Norwegian territory or territorial waters should, as far as possible, be laid in such a way that the aircraft can be observed from Fulehuk Lighthouse (lati- tude 50° 10' N., longitude io° 36' E.) or from Skiptvejt Church, about 30 kms. east of Moss, as well as from the above-mentioned places. The places mentioned in this paragraph are shown on the attached map. 3. Prohibited Areas No foreign aircraft may fly over the following areas, or approach their borders, within a distance of five kilometres (except alons; certain routes determined by the Ministry of Defence) unless notification of the passage of the aircraft is of Blindevannet—north end of Svanevanne—northern point of Lago. Within this area flight at a maximum altitude of 200 metres is permitted above the fairway in the middle of the Christianiafjord and the Drammensfjord (Svelvik river). Horten.—The area between the South end of Basto—Adal Station—railway line as far as Nykirke railway station— south end of Molen up the middle of the fjord to the southern point of Basto. Within this area flight at a maximum altitude of 200 metres, is permitted above the fairway between Horten and Basto.
