If I built a flight plan with FSBUID 2.4. including the TOC/TOP in the Build Options, will it create a plan that will automatically descent to capture the ILS at the arrival airport?

No, the plan will include the waypoints but it is you the pilot and the aircraft that will determine what happens from then on.

 

If properly setup, the FMS will calculate the TOD and if you give it permission (MCP ALT window) it will automatically descend in VNAV. It won't automatically capture the ILS unless you set that up correctly (freq, course, app mode, valid intercept heading/alt).

Thanks Jay for the clarification, So since I have included in the built option of the FSBuild the TOT/TOD and set the FMC properly the MPC ALT indication will automatically display the new altitude of decent and FMC/AP will decent the aircraft to this new ALT. When then I enter the ILS I will take take over to land the plane ( set the correct frequency, direction and press APR. Is the above correct?

Your flight plan won't include TOC and TOD - it's the FMS that calculates those points (since they also depend on your current weight, winds, temperatures etc.; only the box can know those values).

The MCP Altitude wont do anything automatically. Before the TOD point YOU have to change it to the first altitude restriction on the descent. Then the a/c will descend from the TOD point.

 

When intercepting the LOC of the ILS you can either do this in VNAV mode or in HDG SEL mode. Usual practice is to be in ALT HLD with LOC armed. Once LOC captured press APP to arm G/S also. The choice is then yours to either configure for autoland or to allow the A/P to fly you down to a point where you disconnect A/P and land it yourself.

So then, what is the point in FSBulid to have in the "build option" to include or exclude TOC/TPD ? I thought that when you export the flight plan created in FSBuild, FMC will take care of this.

FSBUILD TOD/TOC are not exported - they are just rough indicators where in your flight you gonna reach them. The calculations of these points within the FMC is what matters!

Have you tried the two tutorials yet?

OK Now I get it I was under the impression that the TOD/TOC were in fact imported and FMC will take care of this or at least give me an indication ( a display or something when to descent). I will try the Tutorials hough as you have suggested and see.

You wont get an accurate TOD point until you have entered winds/temps for the descent, so there is no point trying to establish it beforehand.

The FMC does give you indication when calculated climb starts or ends (T/C, T/D). Just look on the nav display it will be written in green symbol and text. It also gives you estimates in various CDU/FMS pages like the progress and cruise page. When you get near the top of descent you will get a FMS message pop up informing you to reset the MCP Alt to a lower ALT (if you haven't yet).

 

But yeah do the tutorials, it should all become clearer.

The main reason is so that you can figure out how much cruise wind is going to affect your time enroute. That's what they're in AS2012 for.

 

Don't rely too much on external programs to do your thinking for the plane or yourself. You really don't want anything telling the box how to do things. Let the box do its job. FSBUILD is meant to be very generic to cover all sorts of aircraft. That's like me trying to use the brakes on my car to run a Formula 1 race. It'll work, but it's not going to get the job done in the best manner.
