Unfortunately it is indeed that difficult.
You can't just lob a system into a cockpit or flight deck (even for commercial air transport), it has to be integrated. Potential interference with FBW, displays, warnings etc, all have to be quantified to ensure there are no unwanted impacts on airworthiness. Where do you take your power supply from? Current running through wiring generates an EM field, so you need to know what that does to the rest of your systems. Where do you put the display? Does it interfere with (eg) sight lines during AAR, or generate another blind spot in the pilot's field of view? What training do you need to rank FLARM warnings with any others your aircraft might be producing? Will the display interfere with escape systems (contact with equipment during ejection and the like (OK, not A400))? Is the display compatible with NVGs? What is the logistics tail? Mean time between failures? MEL considerations and operating regs? Servicing? Documentation?
There will be other technical questions too.
