With regard to TVSA:
- There are two approaches to RWY04: RNAV(GNSS) and NDB.
- Current iFly navdata has RNAV 04 (without GNSS) and NDB.
Of course, GNSS = GPS, so that approach is certainly usabIe.
Is the omission of (GNSS) due to file space limitations?
Yes, and the NDB approach can´t be coded due to the missing procedure-ident …
Hope that helps,
Richard
But Jim, only to clarify that´s from the standard ARINC424 specification - that doesn´t mean that we are not able to add such a prefix by ourselves - if you want

Thanks, Richard.
