G'day Bob
I read some where that the reason why the letter Z or Y is suffixed to an RNAV chart title is because the FMS database can't handle having two approaches to the same runway using the same navaid system to prevent confusion also a suffix Z means a lower MDA compared to suffix Y. ?
Bob could you please make it clear wether or not this is true, also can you explain why the difference between an RNAV-Z (gnss) RWY 14 and an RNAV (gnss) RWY14 when both examples are runway approaches?

G'day FF,
DAP 1-3 might cast a little light on the subject:
As for the different minima, I have not heard of that before, and if you check ILS Z and Y for YBAS (Alice Springs), you will see the minima are identical in both.
