Leading Edge Anti-icing system C130
I operated C130A-E & H models and I can assure Eddietheagent that all or any engine could provide bleed air for the Leading Edge Anti-Ice system. The C130A did not have the luxury of wing isolation valves. Six pneumatically actuated, solenoid controlled Anti-Ice Valves were used. Two in each Wing and two in the Vertical Stabilizer, Horizontal Stabilizer sections. Bleed air, for either Wing Anti-ice or Vertical Stabilizer/Horizontal Stabilizer Anti-ice was taken from the Cross Wing Bleed Air Manifold which could be supplied by any engine. Later aircraft were fitted with the Wing Isolation Vales as mentioned by Chiltern Flyer. Like CF I can see no reason why the J model would be any different to the earlier models in basic design. It costs big dollars to re-design systems and if it had worked well up until the J, why change it?
