Hi,I've only just started to fly the J4100 and have a question regarding the FMC. If I want to enter a route and only specify my departing rwy and then DCT to my first fix is this possible? To me it seems I'm forced to choose a SID and/or transition.For instance I have a route like this...ESSA SID RESNA T314 DEGAL L870 OSS T405 NETAV P600 LURAP STAR ENTCand I would then be able to go direct from the dep rwy at ESSA to RESNA.Is this possible with the FMC in the J4100 or do I always need to use a SID?

Is this possible with the FMC in the J4100 or do I always need to use a SID?

No need to choose a SID. Many smaller airports don't have them at all.

I know that, what I don't know is how to choose a dep rwy in the FMC without having to also choose a SID and transition but I've just started to learn the J4100 so I guess I figure it out after a few more flights.Now on my last flight I faced another problem using the FMC. If you look at the pic below I was coming from OSS on airway T405 and I wanted my next waypoint to be NETAV but no matter how I tried I was unable to select it trying to use the LSK 1L. I ended up changing my flightplan so I went direct from OSS to NETAV instead.

Hi Richard, just choose the SID and use "direct to" button to set the fix You want to go to. Cheers.

That's a good tip, I'll try that on my next flight - thanks :(

Instead of selecting departure and sid enter airport code as first waypoint. This way you won't even have to choose runway. As for selecting this waypoint pews the lsk twice, that should do it.Grzegorz Furmanski.

In fact that is the way I've been doing it having the dep airport as the first entry in my flightplan but beeing more familiar with Boeing FMCs I'm used to always enter my dep rwy as part of setting up the FMC before each flight.

I am not sure exactly what purpose it serves in a Boeing FMC to program the departure runway when you don't fly a SID (other than to display the runway symbol on the navigation display). The FMC in the JS4100 doesn't seem to need it, at least not in the simulated version.I don't remember having trouble selecting waypoints on an airway, but the FMC does sometimes misbehave, the programming does not seem quite as solid as in the 747 or MD-11. You learn to work around it. (In your example the end result was the same, since the FMC in the JS4100 doesn't store the airway information you enter, only the waypoints).

Makes sense what you say and I'm sure after spending some more time in the J41 we will learn to get along just fine the a/c and I :(

As for selecting this waypoint pews the lsk twice, that should do it.

Should be press :), was writing that on my mobile browser and it autofilled it this way for some reason. Grzegorz Furmanski

:( Thanks but I understood what you meant but I did press the LSK many times but it just wouldn't let me select that waypoint so maybe it was a minor bug of some kind. Not a big problem though since I solved it easy by going DCT instead.
