FMC quiz

[metamarty]

I've just completed a new feature and I thought I might as well make a quiz out of it so people might learn something. :-P

Below you see a 737 ND, showing an FMC feature:

4309

What is the name of this feature and why is this useful?

Wow! nice work, i think is offset feature good for weather avoidance...

Good try, but not correct. An offset feature would move the path laterally. The turns would remain intact.

[dcutugno]

That is true, i didn't notice the waypoint where different, so now i think a secondary flightplan...

Hi Marty,

My guess is "DIRECT TO" SOKSI intersection and continue from there.

With DIR-TO no waypont in between actual pos and SOKSI so i think no Direct to function...

[ANDYSMITH]

Hi,
I was thinking that it was on a STAR and the "added" waypoints would be for speed/alt numbers in the FMC

You are getting close. The aircraft was on a STAR and a directo to SOKSI was issued by ATC. But this still doesn't solve the extra points visible.

DIR TO with ABEAM waypoints, at least on the A320 that's how its called :cool:

Yes, that's it! You have just won a virtual trip to your favourite holiday destination using your simulator of choice. :mrgreen:

[jeehell]

Wooohoo!! so excited!!
;) :mrgreen:

To clarify the abeam points function:
When a direct-to is entered in the LEGS page, the option "ABEAM POINTS" is selectable. When using this feature, all intermediate waypoints that are about to be deleted, are moved onto the direct-to route.

Now part two of the question:

Why is this better than a direct to without the intermediate waypoints?

[JWS]

I'm out of competition because I know the answer from the book I showed Marty. :lol:
If he is able to put all the stuff that is in the book into the FMC you all are going to be stunned.

Keep up the good work, Marty.

im not very sure, but maybe, if atc asks you too track to a waypoint, say NHJ (made up!) when you are abeam another waypoint, say HKI? this might make no sense, nothing usually does when i try and explain :p anyway, im enjoying findinbg outabout little things like this :p

Hi JWS,

waiting for someone to give the correct answer...
But after that, could you disclose which book it is, that you refer to???
Thanks in advance.

edit: This thread could turn out to be a worthwhile reading for quiet sundays with more FMC questions coming up, when you can´t bother your neighbours with all those loud sim manufacturing noises, hehe.

Yeah Chris, I will. It's a book that I bought a couple of years ago and I can reccomend it to everyone. Tune in next week, when you hear ......:wink:
