 In terms of fuel, the main fuselage tank contained up to 1,000 litres (220 gal), while a further 250 litres (55 gal) could be accommodated in each tip-tank.A feature that was intended to be used in emergency situations was the provisioning of the tip-tanks with electrically-actuated valves, which enabled the rapid dumping of any remaining fuel.Actuation of the flaps, dive-brake and undercarriage was provided using electric motors delivering power via flexible shafts and Lear electric motors.
