First and foremost,thank you very much mr loop for the info you've provided.I sincerely appreciated it.I was actually looking for a cross sectional diagram of the 800 & 900 series which has the labelling of every parts of the engine provided in it.Its like those pull out spreads you'll get from Flight International.The reason as to why I'm asking for the parts is because I'm actually doing a thorough study on both the 777-300ER and also the A380-800 and the engines are just one of the many chapters.I'm looking for more technical stuffs on both these types,everything from their avionics,powerplants etc.I've tried looking around many other sites but there's not much info that's available.I really appreciate it if you guys could provide some useful links.Thanks!
