OK I give in. What is a B737efis?
And what is a B737 classic. I see its got a HMU so it can't be a B737-200. (Now that is a classic aircraft!)
Anyway the B737-400 has an efis, and it has CFM56-3 engines which have big mechanical HMU fuek control units and no FADEC.
It has a big steel cable going out to the engine.
Perhaps your B737efis had CFM56-7 engines with a fadec and electric wires, but mine has steel cables.
A good guide is that if it has a FADEC then it has electric wires.
But it gets muddied with RR.
The RB211-535 has steel cables
The RB211-524G (B747-400) has electric wires, but no FADEC!
Now the B767 can have either steel cables or electric cables depending on the engines.
Just to confuse.
But I am still confused over the term B737 classic.
If this is a B737-300 (with or without efis), then what do we call a B737-200?
