576 FLIGHT. JUNE g, 1938. oxygen. It has, of course, the hook under the fuselage for picking up messages. The standard armament consists of three machine guns, two of them in the wheel fairings and a Lewis gun for the observer. As already mentioned, when used as a bomber, the machine carries the bombs on two small stub wings bolted to and easily removable from the under- carriage U-tube. One very great advantage of the unusual placing of machine guns and bombs is the remarkable accessibility. " Bombing-up " and machine-gun adjustments and inspec- tion can be carried out conveniently, as the height above the ground is but two or three feet. The Service will appre- ciate this feature when in the field. With an empty weight of 4,065 lb. and a disposable load of 1,855 lt>., the Lysander has a gross weight of 5,920 lb. When fully loaded it has the following speeds : — Sea level .. . . . . . . 206 m.p.h. 5,000ft. . . .. .. . . 220 10,000ft. . . .. .. .. 229 ,, 15,000ft. .. .. .. . . 223 ,, . 20,000ft. .. .. .. .. 212 ,.,, The minimum flying speed (engine on) is 55 m.p.h., and the landing speed 52 m.p.h. It will be appreciated that a speed range of 4: 1 is very remarkable. The sea level rate of climb is 1,650ft,/rain., and the different altitudes are reached as follows:^—', • 5,000ft. in 3.1 mill. 15,000ft. in 11.4 min. 10,000ft. in 6.8 ,, 20,000ft. in 19.5 ,, At 5,000ft. the rate of climb is 1,530ft./min. ; at 10,000ft. 1,180ft./min.; at 15,000ft. 830ft./min.; and at 20,000ft. 500ft. /min. The service ceiling (height at which rate of climb has dropped to 100ft./min.) is 26,000ft. approximately. The economical cruising speed is 150 m.p.h., and the range in still air at that speed is 600 miles. With full load the take-off distance to clear a 50ft. obstacle is 230 yards. Reynolds extrusions used in the Lysander. The smaller ones are used for window frames and similar purposes, while the central one is a main wing spar extrusion. Behind that are two standardised channels used extensively for making forked lugs. The extrusion on the right is used for the lift struts. and the take-off run itself 165 yards. With brakes on the landing run is 200 yards, and the approach distance over a 50ft. obstacle to rest 330 yards. Altogether, it can be said, that the West-land Lysander is a remarkable machine, '/•> . ~ , .
