No, IAN is for straight in approaches. Think NDB/VOR or RNAV Z approaches. RNP with curved legs should be flown using LNAV / VNAV as per the FCOM.
what is the definition of a “straight in approach”? I saw somewhere that this is around 3degrees of centerline. Is that correct? Does that mean you shouldn’t do an IAN on an OFFSET approach?
