Hello folks ,
I'm transitioning from the S92A to Agusta 109S (grand) and during my IFR type cert. training I found a kind of "weird" limitation on its Flight Manual and That says on Part 1 Sec 1
"AVIONICS LIMITATIONS"
-- GNS430 and GNS530 systems must not be used for GPS approach.
So , I'm very impressed about it , I couldn't figure out why Agusta has limited those two GPS Units for performing GPS based APP even meeting all TSO's requirements ( C129a , Class A1 , terminal , en route and app)
I need to show the local Regulators that the A/C complies with ICAO PBN requirements but having this manufacture statement it going to be hard.
Does anyone could help me out to understand why is limited ?
thanks guys
