Some RNAV DPs have a MOCA and MEA on certain segments yet some do not.
Reference KMIA DEEEP ONE SID (RNAV): Most of the segments have a MEA and MOCA.
Reference KCLT DEBIE SIX SID (RNAV): None of the segments have a MEA or MOCA.
Since some aircraft RNAV systems use DME/DME and DME is based upon ground stations, I am assuming the line of sight principle applies of which make sense to have a MOCA and MEA for these type of navigators. And of course there has to be a minimum altitude for GPS navigators for proper terrain/obstacle clearance and communication reception.
Question 1: Why do some RNAV DPs have a MOCA and MEA on certain segments yet some do not?
Question 2: Since a DME/ DME RNAV system can be used for the KCLT DEBIE SIX, why is there not a MOCA or MEA ?
Thank you for the feedback.
