I haven’t even looked at failure yet, but I’d be REALLY surprised if you can’t fail other systems like alternators/generators, flaps/gear, etc. Especially when it comes to cockpit systems. Pitot/static, vacuum systems, as well as individual instruments, were all available for failure in other sims for the last 20+ years. Maybe because this sim is so heavily focused on glass cockpits, they didn’t think it was worth the effort?
