Airbus PPOS
Hi Everyone
I know the subject has been brought up several times and though I found some good info using the search function, I still need some clarification
Here's what I think is correct:
1) in order to get PPOS, one needs to fly into a discontinuity.
2) if one clears the to waypoint while in heading, PPOS becomes the From waypoint .is that correct?
3) there is a scenario that is often used as an example to explain the need to keep PPOS as the from waypoint: you are flying wihtin 5nm of the runway (E.g: Abeam the airport) or overflying it. If you don't keep PPOS, the flight plan will disappear as the plane thinks the plane has landed.
can somebody please explain that properly?
Does it matter which point is the TO waypoint? Can it be the FAF for this to happen? The runway itself?
Finally, if there are any other rule that any Airbus pilot should know regarding PPOS, I'd apreapprec it if you could list it along with the FCOM/FCTM reference so I can look it up.
Thank you
