Hi everyone,
Forgive me if this may have been discussed before but, I am currently working on an uni assignment where I must discuss the benefits vs limitations of RNP.
I have found a mountain of information regarding the benefits of RNP (eg: saves fuel, reduces spread of noise, lower minimums, etc). However I have not been able to find much information regarding the
limitations of RNP. The only issues with RNP I have found so far are:
> Maintenance Costs - maintenance facilities may have to meet a higher standard of maintenance. (source:
http://www.aea.net/AvionicsNews/ANArchives/RNPJan08.pdf )
> RNP cant be coupled to auto-land (i dont remember my source for this)
> A somewhat lack of contingencies if sudden failure were to occur on approach at such low minimums (AC90-101) "The operator’s contingency procedures need to address at least Failure of the RNP system components, including those affecting lateral and vertical deviation performance (e.g., failures of a GPS sensor, the flight director or automatic pilot)"
I guess this is why its called a 'research assignment' - yet i simply cant find anything in regards to 'cons' of RNP
Any help is really appreciated
