FLIGHT NOVEMBER 2OTH, 1947 Introducing the Viscount fuel tanks are of the flexible crashproof type, and Viekers' own experience of a crash in which these tanks were in- volved confirms their view that they will successfully with- stand impacts which would normally rupture metal or integral type tanks. The undercarriage is of the nose.wheel type, and each of the main legs carries two wheels. They retract forwards, in about six seconds. The airframe has been designed to with- stand any vertical gusts which are likely to be met at the operating height, and consequently gust alleviators have not been incorporated. Safety Measures Anti-icing has been designed on the thermal system. Exhaust gas is collected from the jet pipe of the turbines, mixed with air and passed through the wings and tail unit, the temperature naturally being controlled. Double slotted flaps have been included to reduce the landing speed, and provision will be made for reversible airscrews, but the first aircraft will not be so fitted, owing to the already complicated airscrew controls on turbines, and further development will be necessary before it can in fact be included. The forward view from pressure cabins is generally rather poor, but Vickers have set out to make the Viscount's view forward at least as good as that on the Viking. To accomplish this, the canopy has been designed as an excre- scence on the natural shape of the fuselage, with the result that despite pressurization, a wider field of view than that of the Viking has been achieved. There is ample headroom for the pilots both when seated and when (Top) Structural details of the Viscount fuselage. Of particular interest is the window-frame construction. (Centre) Interior layout will be similar to that shown in this sectional view of the fuselage. The seat design wUI be as in the separate illustration.

Incidentally, the cabin has been fitted with largg- elliptical windows, which will allow passengers a particularly wide view from their seats. After much study, Vickers found that an elliptical hole required the smallest weight replacement to make an effective seal for a pressurized fuselage. A single reinforcing member around the hole was found to be adequate. The cabin has been designed to accommodate a Captain pilot, second-pilot navigator, radio officer, and steward. There is no navigation station, but a folding table on the starboard side of the second pilot's seat is easily brought into position for writ- ing, and the starboard control column can be dis- connected. The pantry is amidships in the cabin. A rather neat innovation is the loading hole in the floor of the pantry to allow loading and un- loading of a trolley beneath the aircraft. The automatic pilot is the new Smith S.E.P.i, and standard equipment will include the Instrument Landing System, and miniature GEE suspended
