Hi,

 

On some SID/STAR procedures I can see that such target altitude exist.

 

They are displayed in FPL pages with an up or down arrow prefix, and as far as I know, they are correctly handled by the VNAV autopilot function.

 

Question is: how can I set one myself to a waypoint from the FPL pages and menus?

 

Thanks and sorry if it has been already asked.

Just click on RIGHT button in FPL page. Then you can set altitude and how many miles before that point you want to be at that altitude.

Thanks, you were so fast :wink:

I'll try asap tonight.

Well, I'm in front of the FMS now and a little bit lost:

- With RIGHT key I can enter the wished altitude for sure, what about "how many miles before"?

 

There is no '/' char to separate inputs

Ok, did my homework with the systems description doc.

It seems that before/after WPT distance can be set on VNAV page, 2nd field on the TO line.

Will try tomorrow.

well worth the puchase

Seriously? You answer a question by promoting another product? Bad form, man.

"At or above" and "at or below" altitude restrictions cannot be programmed in to the Universal FMS by the user, although they are included with some SID/STAR procedures. This is as per the real aircraft.

It seems that you are wrong as the method found in the systems description is effective. I've checked that the VNAV waypoint can be set with a + or - distance value in the field prior to the altitude target, so that sounds good.

 

I still have to confirm it's correctly understood by the flight director in various conditions, and be sure of the meaning of +/- input selector. Logically speaking a positive value should mean 'after' and negative 'before' the waypoint so we reach the equivalent of below / above.

 

It's a good think for me to go back in the documentation as I missed several major FMC capabilities. For example I was still flying the ILS intercept in the old fashion, switching from FMC source to HDG, then NAV/ILS source, but FMC can handle the whole thing in a more efficient manner -_-

I had missed also the ILS auto-tune function as well, can you believe it :o

 

Always a lot to learn on my side :rolleyes:

Yea why not  if  you want  to learn  how to fly  the q400   than this is  product  to get.

I confirm this is perfectly working as expected  :smile:
