OCTOBER 6, 1921 NOTICES TO AIRMEN •France: Temporary Obstruction at St. Inglevert Aerodrome WORK is in progress at St. Inglevert Aerodrome in con- nection with the levelling of the ground and the renewal of ground markings. Pilots are, therefore, warned to exercise great caution in landing. Authority : French Notice to Airmen No. 36 of September 5, 1921.; (Where the Notices are abbreviated by us, full forms should be obtained from the Air Ministry.) Wireless Direction Finding Stations : British Isles,. France, Germany and Italy ""•' THE following details (abbreviated) are substituted forthose given in Notices to Airmen, Nos. 17, 30 and 44 of 1921 :— ' British Isles.—1. Stations /—Berwick (Call Signal, BVG) j Carnsore (BVZ) ; Croydon (GED) ; Flamborough (BVN) ; Lizard (BVY) ; Pulham (GEP). N.B.—Aircraft, when within an area northward of the parallel of latitude 51 ° 10' 00" N., and westward of the meridian of longitude 8~ 30' 00" W., should not ask for bearings from Carnsore, as such bearings from it to aircraft in the above area will probably be unreliable on account of the effect of the coastline, the night error in particular being of con- siderable magnitude. 2. Procedure to be followed. France. 3. Stations:—-Barre de l'Adour (Call Signal, FEU) ; Ben Negro (Tunis) (FUA FUB) ; Bernieres (FEB) ; 7 Berre (FED) ; Bizerte (Tunis) (FEQ) ; Brest-Moulin du Seigneur (FEI) ; Casablanca D.F. (Morocco) (CNP) ; Cher- bourg (FUC); Djidjelli (Algeria) (FEJ) ; Gris-Nez (FEN); Guipavas (FEG) ; Kenitra (Morocco) (CNK) ; Lorient (FUN) ; Ouessant (FEO) ; Penmarch (FEP) ; Point du Raz (FER) ; St. Nazaire (FEZ) ; Sfax (Tunis) (FUS) ; Soubise (FES) ; Toulon-Liberte (FUT) ; Treguier (FET). N.B.—I. French D.F. Stations normally use the wave length of 450 metres ; thev also take bearings on 800 metres, and in exceptional cases on 600 metres, but the use of this latter wave will shortly be discontinued. The stations keep watch and answer calls on the 600 metres wave, but transmit bearings on 450 metres, with the exception of Toulon, Ben Negro and Casablanca, all of which transmit bearings on 800 metres. II. The method to be followed by the aircraft depends on various circumstances, but it should be observed that— (a) Bearings can be taken simultaneously by several D.F. stations on the normal wave of 450 metres. (b) If the D.F. stations are not keeping watch on the same wave, each station should be called separately. • (c) If several D.F. stations are specially connected by land telegraph line, one station only need be called (i.e., the nearest transmitting station). The results are sent by this station, each bearing following immediately after the call signal of the station making the observation. Such connection does not, however, yet exist. 4. (Method of procedure follows.) Germany. 5. Stations :—Borkum (Call Signal, KBO) ; List (KAO) ; Nordholz (KBQ) ; Wilhelmshaven (KAN). 6. (Procedure follows.) Italy. 7. Stations:—Murano (Call Signal, IRM). N.B.—Bearings from this station are to be obtained by calling Carbonera ICZ on 600 metres, and are transmitted for Murano by Carbonera. - 8. (Procedure follows.) 9. Cancellations.—Notices to Airmen, Nos. 17, 30 and 44 .. of 1921 are hereby cancelled. . „ ,.....,.; (No. 69 of 1921.) r-:-;.--.••••'' I*"•••'-•- " :"'-V>' -:-"" France : Aerodromes, Etc. •• PREVIOUS notices 4:O airmen relating to France are ampli- fied and amended as follows :— 1.
