The integrated solution is nice and compact, and you can use less tubing, so I thought that Eurocopter and Bell have a good reasons not to use them.
The front of the aircraft is ideal for dynamic pressure measurements (pitot tubes), but not for static pressure measurements. Vice-versa for the static port locations. Therefore, the total result could be worse.
The certification leaves some space for interpretation. Maybe the AW169 system is just good enough. Or it is perfectly fine. That is what I was curious about.
