RNAV initial offset onto ILS

[FlightPathOBN]

OK,

I dont think that qualifies as RNAV to ILS, it is simply a Point in Space Navigation, with a vector to the ILS capture.

There have been a few trails looking at this. The issue tends to be the terminator for the procedure in the coding. We have been looking at RNP transitions to an ILS final for sometime, but the transition to capture tends to be more abrupt than acceptable.

According to Airbus, they were successful in a trial, once, but have not seen or heard of any use.
