27 July 1951 121 of a "go-slow" strike by more than 500 ground-crew membersemployed at Northolt. Last Saturday 42 services had to be cancelled and on Sunday this figure had risen to 50. The strikersare members of the Association of Supervisory Staffs, Executives and Technicians who began working to rule after an offer of awage increase less than that demanded by the Association. Thus B.E.A., it seems, is faced with another considerable financialset-back which it is not in a position to offset by offering additional capacity later on. To help meet the shortage of trained air-crewsit is understood that the R.A.F. is to make available (thought to be eight) a number of radio operators on indefinite loan to B.E.A.Tney will wear the Corporation's uniform but will receive ordinary Service pay. AER LINGUS PROFIT AER LINGUS has announced a profit of £14,646 on its• operations during the financial year ended March 31st. Gross revenue, at £1,300,000, showed an increase of about£160,000 over last year's figure. For the same period, however, expenditure ipcreased by over £100,000, due to aTise in operatingcosts and an increase in capacity ton-mileage flown. The company's operations, with a standardized fleet of DC-3S,have been conducted at a very good passenger load-factor of 69 per cent (the o.r.l.f. was 65 per cent) and this fact, together with theexercise of stringent economy on overheads has enabled Aer Lingus to hold its own against the general trend of rising costs in Europe. The Holy Year traffic, involving the carriage of over3,000 pilgrims by special charter flights, also helped to swell traffic on the company's routes to Paris and Amsterdam. Aer Rianta, which holds a 60 per cent interest in Aer Lingusand is responsible for the running of Dublin Airport, also showed a small operating profit of £3,884. Its general administrationaccount (covering the company's activities other than the manage- ment of the airport) resulted in a deficit of £4,176. AUXILIARY POWER FOR DC-3s THE controversial problem of whether or not to extend theutility of the ageing DC-3 by re-powering it. with a more suitable engine is one which has been in the minds of manyoperators during recent months. One difficulty is that in Europe, at least, even re-conditioned American engines of higher powerare virtually unobtainable. Of special interest, therefore, is the French project (of which an example was shown at Le Bourgetrecently) to give auxiliary power to DC-3S by equipping them with a Turbomeca Palas turbojet. By affixing this unit beneaththe fuselage, the installation is achieved without the need for any major structural modifications, cheaply, and with a very slightincrease in weight. The additional thrust available at take-off allows an augmentation of about 1,540 lb in payload and enablesthe gross weight to be increased to 29,000 lb. Equipped with the Palas, she DC-3 is claimed to satisfy I.C.A.O. requirements withregard to single-engine flying.

These show that, in all, the Corporations enjoyed approximately one-third more traffic than in the previousyear. The actual totals achieved were 835 million passenger- miles (an increase of 32 per cent), and 24 and 13 million freightand mail ton-miles respectively, representing increases of 30 and 18 per cent, over the figures for 1949-50. The average passengerload-factor for both Corporations fell from 62 per cent in the previous year to 57 per cent last year. The overall revenue loadfactor, however, rose to 59 per cent as compared with 57 per cent in the previous year. B.O.A.C. increased its total traffic by 31 per cent to 84 millionrevenue load ton-miles; the o.r.l.f. also rose by 4 per cent. The Corporation carried 196,000 passengers for a total of 569 millionDassenger-miles at a load-factor of 56 per cent. Traffic was seen to be highest on services in the Eastern Area, where it reached 57million load ton-miles. In this area, also, the o.r.l.f. rose to 67 Per cent as compared with 60 per cent in the previous period. B.E.A.'s total traffic also improved considerably, reachinga total of 28 million revenue load ton-miles as compared with 22^ million in 1949-50. This traffic was carried, however, ata reduced load-factor of 58 per cent (as against 61 per cent last year). The totals achieved for passenger traffic were 948,000 pas-sengers carried and 266 million passenger-miles flown. B.E.A.'s passenger load-factor was down by 4 per cent to 59 per cent. In general, improvements were more marked on the Continentalroutes than on those within the United Kingdom, the respective increases in revenue load ton-miles flown being 30 and 12 per cent.Overall revenue load-factors in the British Division declined to 55 per cent from 61 per cent and to 59 per cent from 62 per centin the Continental Division. Charter firms operating under associate agreements with B.E.A.also enjoyed improved traffic. Passenger-miles flown rose by 13.3 per cent for a capacity increase of 14 per cent. The most spec-tacular improvement, however, was seen in the carriage of mail which increased by 128.2 per cent. The average o.r.l.f. forscheduled services flown under associate agreements was about 51 per cent, although the figure for the purelv passenger-carryingflights stood at the more satisfactory level of 58 per cent. Detailed traffic statistics for both Corporations and for thescheduled services flown under associate agreements with B.E.A. are given in the table above.
