P-RNAV/RNAV-1
I'm a slightly confused controller that can do with a little education please!
RNAV-1 routes are beginning to pop up in various places however someone has told me that the aircraft has to be turned into "RNAV-1" mode by pressing a button and doesn't fly it routinely. Is that correct?
Second question, how aware are you as a pilot that you are now on an RNAV-1 portion of a route, and would you fly differently?
Last question, can you be RNAV-1 compliant and manually flying or does the FMS have to be in full control?
Thanks in advance.
