FUGHT. 3 November 1949 583 CIVIL AVIATION NEWS..; c and cargo in addition to a 150-lb baggage allowance ior eachpassenger. Adequate space should be provided for accessible stowage of personal belongings, life jackets, pillows and blan-kets, each seat should have a separate reading light and atten- dant call-button, and arrangements should be made for theserving of two full meals. The cabin should be designed, he thought, to provide apressurized altitude of not more than 8,000ft regardless of the aircraft's actual height, and a self-contained air-conditioninginstallation, operative both in the air and on the ground, should provide a cabin-tempeiatnre range of from 65 to 80 deg F.Large windows fitted with a de-frosting device should be in- stalled, and an address system provided to relay " music whileyou fly." Gen. Harris considered that the crew should number five inall, three of whom would be pilot-navigators and two cabin attendants. Only pilot-operated R/T. communication wouldbe used, and a flight engineer carried only if the aircraft had reciprocating engines. Desired performance should include theability to fly non-stop in both directions between New York and London with full load, speed to be as fast as possible withindesirable operating limitatioas, with not more than 2,000 yd runway length tor landing and take-off, regardless of air orgeographical conditions at either airport. The aircraft should also be able to reach an airport from any point en route afterlosing 50 per cent of its engine power. Such a machine might well be forthcoming if the cost envisaged by Gen. Harris—' 'notmore than $2,000,000 (£715,000) per unit'*—could be con- sidered economically feasible. V.H.F. R/T. COVERAGE /"MVIL pilots flying over the Aberdeen-Shetland route inv-^ north-cast Scotland can now maintain constant R/T com- munication through the five civil airfields on the route. Thenew system erf " coatinHOBs voke communication " has been made possible by the provision of V.H.F. R/T communicationsystems along the roate, incorporating a V.H.F./D.F. service on the sam« wavelengths. The M.C.A. is responsible for theinstallation, which is the first of its kind in this country. Airports so equipped are Dyce (Aberdeen), Dalcross (Inver-ness), Wick, Kirkwall (Orkneys) and Sumburgh (Shetlands), while R/T stations have also been provided at Tarbatness(Moray Firth) and Windyhead (Fraserburgh). R/T coverage for the North-West Scottish routes, including the Hebrides, willfollow. Northern Scotland is the first section of a project planned by the M.C.A. for providing continuous V.H.F. R/Tcoverage, for the whole of Great Britain, the Channel Isles and part of Northern Ireland. The next area projected for coverageis Southern England,"to be followed by Central Scotland and later by Northern England and Northern Ireland. While theNorthern Scotland facilities are designed for specific routes only, Central Scotland, England, Wales and Northern Irelandwill have complete area coverage, provided by a "floodlight"- system employing the multi-carrier principle (a fractional varia-tion in frequencies within a group of transmission stations), use being made of common transmitter and receiver stationsstrategically located on high ground. The transmitters will be modulated from, and receiver outputs fed into, air-traffic con-trol centres at Uxbridge, Barton Hall (Preston) and Prestwkk for Southern England, Northern England and Central Scotlandrespectively. In the last-named case use is being made of exist- ing Gee sites. Existing high- and medium-frequency W/T communicationand D/F systems will become obsolete when the project is complete, except in relation to aircraft flying the North andSouth Atlantic and the trunk roates to the east, for which H.F. W/T will remain. The medium frequencies put oat ofoperation by this plan will "be used for other navigational facili- ties, such as M/F radio ranges and beacons which are to beinstalled under the airways (air corridors) plan. LF.A.L.P.A. CONFERENCE "DEPRESENTATIVES of 13 nations attended the fourth•*-v conference of the International Federation of Airline Pilots Associations, held in Copenhagen on October 10th. A numberof resolutions which had been discussed at previous meetings were ratified, one of the more important being the decisionthat an assessment of weather conditions by a pilot should always be considered as final. On the question of conditions of service, maximum flying-times agreed upon were 85 hr per month and 935 hr per year on short-haul work, and no hr per week and 1,000 hr per yearon long-haul duties; the distinction between short and long hauls was left for settlement between member associations andthe operators or governments concerned. It was agreed, also, that I.C.A.O. should be requested toconduct an investigation into the harmful effects of continuous flying in pressurized aircraft; and another decision reached wasthat I.F.A.L.P.A. should ask to be represented at all future international meetings dealing with civil air-transport prob-lems. Brussels was chosen as the venue for the next annual conference, to be held in April, 1950. BREVITIES IT was recently announced in Sonth Africa that as a resultof devaluation the total cost of four Constellations on order for South African Airways will be about £500,000 higher than was originally expected'. Part of the purchase price had already been paid. ( • • • B.E.A. and Swissair have advanced the date of the intro- duction of their winter excursion fares to Switzerland so that ORNAMENT TO ANY AIRPORT : The new Thompson-Leytand "Tyne" refuefter for targe aircraft has a 4,003-gallon tank, pumping chamber and cab fabricated as a single unit. Each of its two pumps delivers fuel at up to 200 gal/mim and it is also designed to de-fuel aircraft. A " handsome and impressive appearance *' has been aimed at, and the photograph suggests that Thompson Bros. (Bilston). Ltd., have admirably succeeded rn their objective. they became effective on November 1st. Valid for 23 days,the reduced fares will be available until March 31st. Currency exchange rates have not affected the excursion fares, whichare £23 between London and Geneva or Basle, and £24 to Zurich. The regular return fares between the United King-dom and Switzerland have been increased to £28 9s to Geneva and Basle (as against £27) and to Zurich £30 9s (£28 16s). In Notam No. 155 the M.C.A. warns pilots against flyingbelow 3,000ft in the Solent area south of the Southampton Control Zone in I.F.R. conditions, owing to the considerableamount of instrument training and test flying which takes place in that area. Pilots who are obliged to fly within the areain I.F.R. conditions are advised to contact the Southampton (Eastleigh) Approach Control before eatering the area in question. .•-.•' :• • * ••'••••• In the hearing of the compensation claim made by Allied Airways (Gandar Dower), Ltd., against the Air Ministry, concluded in Edinburgh on October 25th, judgment was reserved. The claim was originally for the sum of £7,253 per annum for ten years in respect of compensation for loss of revenue daring the RAJ. occupation and use of Dyce Airfield, but it was later modified to £3.500 per annum. A witness for the Air Ministry stated that in bis opinion, based on compensation awarded in similar cases, £1,250 per annum would be the maximum figure. • • • On October 24th K.L.M. started a weekly service by Doug- las DC-4s between Amsterdam and Baghdad; it is intended to relieve the Amsterdana-Batavia services of Middle East traffic, which is mostly to and from the Kuwait airfields.
