RNP$-$AR$,$ RNP$,$ or just a simple RNAV procedure. Same as last time, you

are required to discuss the following aspects about the procedure: $($i$)$

lateral trajectory, $($ii$)$ vertical gradient, $($iii$)$ aircraft performance

requirement, $($v$)$ minimum operating condition, $($v$)$ airport surrounding

environment.

$$ Some airports selected might not have implemented RNP$-$AR or any

PBN procedure yet. It is oaky to study those airports but you may want

to consider what extra benefits will there be if RNP procedure is

implemented in the near future.

$$ Then, you are required to compare and contract the corresponding

conventional procedure and PBN procedure from the $($i$)$ operational, $($ii$)$

financial, $($iii$)$ environment and $($iv$)$ safety perspectives.
