Like any field there is a lot more complexity they didn't cover in the video, but I would expect the designers did, at least in part. Particularly around pressure drops (especially in lube oil and fuel systems) and fouling (again, in a system like oil) Also I'm surprised they use S&T exchangers on a helicopter. I'd have expected plate or PCHEs, both are much smaller and more efficient. If they're using a S&T there may be a reason for it, but I'm not an aviation engineer.
