tell me about braking system in a330, the component used, the diagram of the system and the operation
Since I have no manual for the A330, it is one of the systems that is the same with the A340. Normal braking is Green sys. Alternate brake as well as parking brake is Blue sys. There are two BSCU (Brake/Steering Control Unit) this is the main brain which controls braking, steering & anti-skid, even cross talk with if equipped with Brake Temp.Monitoring Unit. One BSCU is active while the other is in stand-by in case of malfunction the good BSCU automatically gets active, in case of normal operation during LDG (landing gear) lever retraction, there is a change-over. Ex. in ECAM it is indicated that BSCU 1 is active, after LDG lever retraction or lever up BSCU 2. takes over automatically, until the next gear retraction which is of course, the next leg BSCU 1 will be now in use. A330 & A340 uses carbon disc brakes easy to dissipates heat. In case of hot brakes, in the ECAM brake page in the cockpit there is an eyebrow atop every wheel TPIS (Tire press. indicating sys.) value, and the hotter it is the thicker the eyebrow and color is pulsating green, it turns to amber I think when overheated (never seen one). BSCU is interchangeable you can use it for A330 or A340. As for the diagram, my friend, well I am not good at drawing, am only good at coloring my manual.
