Hi,

 

I got this airplane the other day and it seems quite impressive.  I'm trying to sort out the basics while I'm waiting for my forum access over at Majestic.  One issue is, when in flight, I insert a waypoint into my route while flying along the route.  I successfully added it to the flightplan using the FMS instructions.  So, for example, using the tutorial flight I am flying toward OO and I add ONO (Ontario) after it.  When I go back to the NAV screen, however, the new waypoint is not there and the flight continues on to LERAK.  No, I want to overfly ONO along the way.   Can someone explain how to do that?

 

Thanks,

Gregg

 

EDIT:  Keep in mind this is only for experimenting purposes...ONO would be a stupid fix to put in that route.  My scenario is just to be able to program in a slight diversion into a route and then get back to the route.

Gregg,

 

when you say ONO is not on the NAV screen, do you mean it doesn't show up as your "TO" waypoint? Or are you trying to select it as your next "TO" waypoint and it doesn't show up in the list where you can select those waypoints?

 

If it's the latter, well, I don't know, I've never tried it that way. Others will have to chime in here.

 

If you haven't tried selecting it, though, press the LSK next to "TO" on the left hand side of the FMS and enter the number corresponding to ONO from the list on the right hand side. Just like you did in the tutorial flight (IIRC) after entering the route.

 

Let me know how it goes.

 

Cheers,

Oliver

 

Edit: Keep in mind you'll have to do this on both FMSs in order to have the same display on both sides, the Captain and the FO side.

When you make changes to the flight plan it does not in certain situations refresh the NAV logic, so the flight path it computed from the flight plan exists only on another level above the FPL page, which you can manipulate via the NAV page. This is most plainly obvious when you delete the current TO point from the FPL page and you still see it active on the NAV page. Basically unlike with a Boeing FMC where any change to the flight plan creates an immediate recalculation by the LNAV, VNAV, in the Dash the NAV won't recalculate the amended plan until you reset the NAV page, at least insofar as changing the immediate flight path.

 

Try going to NAV page then resetting the next nav waypoint to be the same one you're going to and it should recalculate the waypoint following it to be the one you just inserted.

 

The FMS in the Dash is a bit slippery. It doesn't automatically do a lot of things for you that other more sophisticated ones will. The biggest difference is that in a Boeing FMC when you make changes which are not immediately activated it tells you this by offering the Execute light. The Dash FMS doesn't and you just have to rely on experience and observation to know when to tell it to do what you've told it already to do.

Thanks.  Your explanation seems sound and I'll try that this morning.  My thinking is that, in the real world, this would be a fairly common occurrence...diverting around wx, traffic or just basic rerouting. 

ATC will normally provide a heading to vector you around traffic or weather.

If you are given a new NAVAID, you can follow the attached guide, taken from the UN-1 manual.
