Some of you people need to do some research regarding the CAO 100.66 system before you shoot your mouths off on here. Five minutes on the CASA website would save alot of the BS some of you write.
Ngineer, you're right, there is alot more avionics on these new types- most of which can be certified by a B1.1 LAME. I suspect a ratio of about ten to one is about right. If a B1.1 guy can cover all Engine, Airframe and Electrical also LRU with BITE on Instrument and Radio how many B2 guys do you need on Line or even in Servicing?
