British Aircraft BA.IV Double Eagle
Страна: Великобритания
Год: 1936

DUPLICATED: Latest of the British Aircraft Manufacturing Company's developments, the Double Eagle is eventually likely to be of considerable interest to the smaller air line or charter operator. The pilot has a very good view in all essential directions and, with the low-middle-wing arrangement, the passengers, too, will be able to take an interest in earthly matters. The engines are Gipsy Majors.
Although its Gipsy Sixes are not of the Series II type and it has fixed-pitch airscrews, Tommy Rose's B.A. Double Eagle is expected to give a very good account of itself.
His mount: The B.A. Double Eagle (2 Gipsy Six) which Flt. Lt. Rose will fly.
Types of competing machines: B.A. Double Eagle
B.A. Double Eagle has an unusual wing arrangement which gives the passengers a good view downwards. Two Gipsy Major engines are used.
One of the B.A. Double Eagles entered has Gipsy Sixes (Series I) and the other Gipsy Majors. The more powerful version should do 190 m.p.h.
The new B.A. Double Eagle with two Gipsy Majors has a very unusual wing arrangement.
