FLIGHT, OCTOBER 5, 1933 METEOROLOGICAL BROADCASTS FROM HESTON /Tip' HE following arrangements came into force on Mon- 0 III day, September 11, 1933. Ill The Air Ministry broadcasts daily, at the times given below, from the Air Ministry Radio Station, Heston Airport, by radio telephony on a frequency of 360 kc/s. (833 m.), weather reports and forecasts, and navigational warnings. The messages are read through once at normal speed and then repeated at dictation speed. Weather Reports and Forecasts.—The weather reports are from stations situated on five routes and in two areas, as follows: — Route (a), Eastern Route to the North. Cranwell, Harrogate, Newcastle. Route (b), Western Route to the North. Upper Hey- ford, Coventry,* Birmingham, Chester, Liverpool, Holy head, Manchester, Southport,* Renfrew. Route (c), West Route. Ross-on-Wye, Pembroke. Route (d), South-west Route. Farnborough, Southamp ton, Amesbury, Portland Bill, Plymouth. Route (e), South-east Route. Croydon, Biggin Hill, Lympne, Dungeness. Area (a), East AngUa. Felixstowe, Yarmouth. Area (b), London Area. Heston, Stag Lane. The reports give the time of observation and the general state of the weather, the visibility, the amount and height of the base of the low cloud and the direction and speed of the wind at each station at the time stated, e.g.-— Amesbury 0700: Partly cloudy ; visibility 3 miles, low cloud 4/10ths at 1,000 ft., wind north-west 5 miles per hour. The forecasts, which are divided into appropriate areas covering Great Britain and Northern Ireland, are prefixed by a statement of the general meteorological conditions existing at the time of issue, and give the surface wind, upper winds at the layer of 2,000-3,000 ft., weather and visibility expected in the succeeding period, which varies, as shown in the time-table, according to the time of issue, e.g.: — " Depression north of Faros. Pronounced cold front Aberdeen to Valencia moving south-east, reaching Mid lands of England this evening and south-east England early to-morrow. " In England, Wales and South Scotland, in advance of front, surface wind south-west, fresh or strong to gale in exposed places with overcast sky and continuous rain. Upper wind 2,000 to 3,000 ft., from 240 deg., 70 miles per hour. Poor visibility and very low cloud. As front passes, wind veering suddenly to north-west with severe squall. In rear of front, surface wind north west, light, upper wind 2,000 to 3,000 ft., from 320 deg., 20 miles per hour. Visibility rapidly improving and sky clearing. " In northern Scotland and Northern Ireland, light west or north-west winds, broken cloud, good visibility." It should be noted that the direction and speed of the wind are subject to possible variations of 10 deg. and 5 miles per hour, respectively, on either side of the figures given in the forecast. Thus, if a direction is given as 245 deg., this indicates that the forecasted direction lies between 235 deg. and 255 deg., while if the speed is given as 30 miles per hour, the forecasted speed lies between 25 and 35 miles per hour. Navigational Warnings.—While conditions of bad visi bility prevail in the vicinity of Biggin Hill and Kenley on the Croydon-Lympne air route, the statement " For regulations in force in Biggin Hill area " will be included in each broadcast. When conditions of bad visibility cease, the statement " Fog regulations cancelled in Biggin Hill area " will be included in the succeeding broadcast. * Coventry and Southport are supplementary, only one raport p;r day being broadcast, S3 SsS £U R.A.F. Accidents THREE service aircraft were involved in accidents while returning from the Coast Defence Exercises, all caused by bad visibility. A Fairey *' Gordon " of No. 40 (Bomber) Squadron, Abingdon, crashed at Bamborough, Northumber land, on Tuesday, September 26, and caught fire. The pilot, F/O. Norman Charles Meyrick, and the observer, Details of the fog regulations referred to are given in the Air Pilot, Volume I, Part 12. Navigational warnings other than the above will be in cluded at the end of the meteorological forecasts only. These warnings will normally only be broadcast prior to the distribution of a Notice to Airmen, and will be omitted from the broadcast as soon as distribution of the Notice has been effected ; in the case of a warning of a sudden and transitory nature, however, the broadcast warning may not be followed by the issue of a Notice to Airmen. When no navigational warning is to be broadcast, the statement " Navigational warnings—nil " will be made at the end of the meteorological forecast. Times of Broadcasting.—The times of broadcasting are as follows: — Winter Time-table (when British Summer Time is not in operation) : — G.M.T. 0845 Weather reports based on 0700 observations. 0930 Forecast for the period from the time of issue until dusk, and navigational warnings. 1030 Weather reports, including recent observations on the S.E. route and from supplementary stations elsewhere. 1130 Weather reports based on 1000 hours observations. 1230 Forecast for the period from the time of issue until dusk, and navigational warnings. 1430 Weather reports based on 1300 hours observations. 1530 Weather reports: Observations supplementary to those given in the 1430 broadcast. 1630 Forecast for the following day and navigational warnings.
