Good afternoon! I have found one demo training module of Lufthansa technic company. Here it is http://www.ltt-onlinetraining.de/Data/ltt/presentation/samples/tae/http://www.ltt-onlinetraining.de/Data/ltt/presentation/samples/tae/. I think it's a good matter for training. (illustrations, voice accompaniment - look module B in menu). So, does anybody has similar sources or matter for TECHNICAL aviation english training? May be some books, videos and etc. Thank you!
