Narrative:
Iah recently published several new RNAV approaches. All of the RNAV (rnp) approaches in iah have the phonetic alphabet 'Y' in the title. At other airports that have RNAV (rnp) approaches the letter 'Z' is in the title. So at most airports we are cleared for RNAV (rnp) Z runway xx approach. At houston we are cleared for RNAV (rnp) Y runway xx approaches. At the other airports; the RNAV Y approaches have (GPS) in the title of the approach- RNAV (GPS) Y runway xx. Rnp and GPS approaches have a slightly different FMC box programming protocol. Not sure if the iah approaches were coded wrong; but it would be nice to have a consistent naming protocol when using RNAV (rnp).
