Leak Detection 2/3 ||Pneumatic system #a320 #leak #detection #pneumatics #loop #flyingaurpeace

Hello everyone I have tried to cover all the relevant information about leak detection, which is important for airline written exam point of view . Please let me know in comments or through direct messages if something left or incorrectly explained. IG Link https://instagram.com/flying_aur_peac... Leak detection loops detect any overheating near the hot air ducts in the fuselage, pylons, and wings. For the pylon and APU, the sensing elements are tied to form a single loop and for the wing, a double loop. When the two wing loops detect a leak, or when one loop detects the leak and the other one is inoperative, they activate a wing leak signal. BMC1 and BMC2 each contain identical control logic for the system.‐ A wing leak signal causes : • bleed valve on the related side to close automatically • the associated FAULT light on the AIR COND panel to come on • the x-bleed valve to close automatically (except during an engine start) • the APU bleed valve to close automatically if the APU bleed valve is open and if the leak concerns the left wing (except during engine start).‐ A pylon leak signal causes : • the bleed valve on the related side to close automatically • the FAULT light for the related engine on the AIR COND panel to come on • the x-bleed valve to close automatically (except during an engine start). • the APU bleed valve to close automatically if the APU bleed valve is open and if the leak concerns the pylon 1 (except during engine start).‐ An APU leak signal causes : • the APU bleed valve to close automatically (except during engine start). • the FAULT light the APU BLEED pushbutton switch on the AIR COND panel to come on • the x-bleed valve to close automatically (except during an engine start). . .A beautiful picture has been taken by plane spotters & Photo copy right of the A320 jet airways livery goes to https://www.planespotters.net/photo/1... #pylon #leak #pneumatics #320 #a320 #crossbleed #bmc #failure #detection #wing #apu
