FMC Question for Brad..

[omarza]

Well at last I got the PMDG 737 as well as the 747... I know i'll be using the 737 alot before switching to the 747 but decided to get it so long for
the longer flights. I didnt have time to really use it thus far as i'm working thru the manuals with heavy focus on the FMC part. Thus far I havent
flow the 737 and programmed a few routes into the FMC trying to get the hang of it first... takes alot of patience to not just jump in and fly tho

You knew I was going to bug you once I got the PMDG 737

The question is in 2 parts... one for Arrival airports with STARS and one for those Airports without...

At what point is it best to switch over to manual landing if the airport has a STAR?

If there isnt a STAR... do you disable the autopilot earlier and fly the final procedures (Approach, Landing) of the flight yourself?

Im just trying to get a roughly feel/understanding of the correct way of doing things as im not used to a FMC... call me an old generation person...

I'm assuming that when you're flying your route, you're using LNAV... these answers are based on that assumption:

Normally, if we're following a PILOT NAV STAR (not a VECTOR STAR, since those are a little different), we can keep LNAV engaged until
the LAST waypoint prior to the runway. Most pilots WILL NOT do this, as they like hand flying the majority of the final approach. Normally,
if using LNAV, I'll deactivate the AP at the waypoint at which I begin my final approach. This way the PAX will only have a bumpy final

You'd be suprised how much LNAV is used. If ATC clears us direct a waypoint, we'll enter it in the FMC via the LEGS or RTE page, and let
the AP fly to it. We're encouraged to use the AP as much as possible, due to the fact that it (usually) doesn't make mistakes! So
essentially, with or without a STAR I'll disable the AP when I begin my final (unless there are gusty winds, or other conditions that make
the use of the AP approach mode more desireable). Just keep in mind that of high concern is keeping the PAX comfortable. If you want
to hand fly an approach with 20KT gusts, remember that you've got to accept responsibility for the consequences of that.

I hope this helps... let me know if I didn't answer your question (which I have a tendency of doing)...

Thanks alot... you have answered my question perfectly and it will be a great help. Ive basically finished working thru the PMDG 737 manuals and will
take her out for a flight tonight.
