For purposes of clarity, the Attackers and Wyverns shown in the hangars are spread out rather more spaciously than would normally be the case, and, purely in order to make the drawing as informative as possible, several flight-deck conditions have been merged. Thus, for example, an Attacker is shown on the catapult, whilst a forward deck-park of aircraft is ranged. It should also be pointed out that this drawing shows H,M,S. "Indomitable" as she was prior to her recent re-fit. Full-load tonnage... Length O.A. Beam Draught Cruising range ...

Like the arrester wires, the barriers canalso be pulled out by an aircraft (or anything else, for that matter) running into them, but the maximum pull-out dis-tances are considerably less than apply in the case of the wires. The barriers are remotely controlled from the (port)deck edge midway between them. The catapult mechanism is a virtual reversal of that used for the arrester gear, in that the catapult trolley is actuated by a cylinder/piston unit through a system of rope reevings to give an 8 : 1 magnification of piston travel. The system is basically pneumatic the pressure of air admitted to the cylinder being adjusted to give the trolley speed required for the weight of the particular aircraft being launched. A rough rule in thin context is 1 lb/sq in air pressure for each 10 lb of aircraft weight. Having launched the aircraft, the trolley is returned by admitting water-glycerine to the cylinder in order to re-compress the air. (Continued overleaf)
