SEPTEMBER 16, 1926 " FLIGHT " Photograph AT THE SALES : Competitors waiting at the petrol " shop "to be served. On the right, in front of the Farn- borough Hawker " Cygnet " may be seen Air Vice-Marshal Sir Sefton Brancker with Capt. Goodman Crouch. and in the end the AID. granted the machine a certificate for a total loaded weight of 50 lbs. more. The final figures for the competing machines at the close of the day were as shown in the accompanying table : Machine No. 1 Type. Blackburn " Bluebird " .. 2 D.H. "Moth" 3 Bristol " Brownie " 4 Hawker (Farnborough) " Cygnet " 6 Hawker " Cygnet " 7 Supermarine " Sparrow II ' 9 Avro " Avian " 10 Avro " Avis " 12 Cranwell C.L.A. 4 . . 14 Parnall " Pixie III " 15 Short " Satellite " 16 Westland " Woodpigeon " \\ eightempty. lbs.721 735 623 431 421 605 695 606 529 522 697 570 Petroland oil. lbs.107 115 47 57 49 55 77 104 61 63 63 75 Useful Totalload. lbs.472 700 340 362 430 340 828 340 340 340 340 340 weight. lbs.1,300 1,550 1,010 850 900 1,000 1,600 1,050 930 925 1,100 985 In this connection it is of interest to examine the " struc- tural efficiency " of the various machines by calculating the ratio of useful load carried to weight of machine empty, bearing in mind that each machine is carrying enough fuel and petrol for the longest circuit to be covered non-stop in the competition, i.e., 122 miles over the Lympne-Eastbourne- Lympne-Hastings-Lympne circuit. Thus, with a range of 122 miles this ratio is as follows for the various machines, arranged in the order of " structural efficiency " : Machine. Avro " Avian " Hawker " Cygnet " . . Hawker (Farnborough) " Cygnet " Blackburn " Bluebird " Parnall " Pixie " Cranwell C.L.A. 4 Westland " Woodpigeon " . . Supermarine " Sparrow II " Avro " Avis " Bristol " Brownie " ..
