I would say the film wasn’t accurate because every single thing in the past has used that setup, EU or not.

Rebels introduced TIEs parked this way, before TFA did.

And by the way… There is a technical manual, u know. Cross-sections, technology etc.
This is a official Disney thing.

And it has the two-seater-TIE in it. And the named every cable, every thing like the engines and the weapon system. And well, there is no repulsorlift in it. Some other ships and vehicles have it.

If there was no official technical manual for TFA this TIE details would be not interesting to me.

But there is one and the film is not accurate to it.

Those technical manuals have never been the most accurate of things. It’s just someone making stuff up basically, and they don’t always represent what is seen on screen.
