As it should be considering Su-37 was never adopted but lesson that was learned on it used on Su-35.
But doesnt change the fact that Su-37 was actually newer (first flight date) and proposed different things when it comes to flight performance(such as canards in that case).
All Su-27M had canarads. Su-37 (Su-27M2) isn’t something special. It’s just Su-27M with TVC engines that weren’t even installed on it for all of its life time.
I don’t know where to ask, so I’ll try here. The Su 27 is equipped with the Ekran system, can anyone compare the Ekran system with the BIT system on US aircraft? I think the difference is that Ekran can tell the pilot what to do and what to check, BIT just shows where the fault is.
