No Active Route on FMC Right After Take Off

Recommended Posts

Hi,

 

I created an overseas route from KEWR to EDDF in route finder. Route Finder give me a GPS direct route via NATS.  I then loaded this route into Sim Routes and created a RT2 File as a company route.  I named the Route:  KEWREDDF001.  I loaded the company route into the FMC, and it loaded rigth away;  the GPS route and distance was duly noted in my navigation display.  Everything seems peachy.

 

As soon as I take off and engage the autopilot L-CMD  then hit the LNAV switch, an FMC message pops up.  When I look at the FMC, "No Active Route" Message shows up at the bottom, and my programmed route is gone.  What happened?  I'm a bit confused.  Is this an issue with a GPS route?

 

Comments are appreciated

Yes, I did. Everthing looks fine..thenI continue on to the Perf Init, Thust limit, and takeoff pages without any problems.  I don't have any issues with the flight plan dropping out when loading a flight plan for overland routes....These routes work fine

Hi, Hornet65,

 

You can arm LNAV (and VNAV) before takeoff.  If something is wrong you should get the "No Active Route" message then, and have more time to figure out why you are getting that message.

 

PMDG wants you to sign your full name in its forums.

Thank you Mike,

 

I'll give that a shot.  Though, if the message "no active route" comes up after arming the LNAV, will the FMC allow me to reprogram and execute the flight plan again after pushing back from the gate....during taxi or on the runway?

 

Also, is there a better "free" site to create flight plans and save as both a RT2 and a FSX PLN file ( I've created mirror routes on overland routes in both RT2 and PLN files.  This way I can load the PLN though FSX, then load the RT2 into to FMC. This allows me to interact with FSX's ATC functions. With the mirror courses, they agree and FSX won't tell me I'm off course)

 

Getting back to my question about a better "free" flight plan resource, Sim Routes is spotty at best...often I'll need to make several attempts before a plan will save.  All I want to do at this point is enter a departure and destination airport and get a flight plan.  I'm spending my time getting used to the 747-400 and its systems, and I'm  not looking to spend a ton of time creating flight plans with some of the payware programs out there.  Some of these resources are quite involved.

 

Thanks again,

After you have entered your compny route, check both the RTE and LEGS pages to see if they make sense. No disco's for example.

 

You can ammend the route at any time.

Thanks For the comments.  I think I'm beginning to understand what the issue is.  Route Finder gave me a GPS route with a Departure and Destination input only.  In my legs page I only see the depature and destination.  So, It looks like the flight plan drops out as it does not really exist as far as the FMC is concerned.  I'm not sure if my PMDG 747-400 is GPS compatible....so perhaps this is the problem.

 

It would be nice if PMDG would allow FSX PLN routes....and use them.  I realize this isn't as sofisicated as some of the 3rd party payware navigation software progams out there...but right now I'm more interested in learning the 747-400 systems.

 

Any suggestions as to a more user friendly "free" navigation utility?

 

Thanks,

well, it sounds like you maybe just don't have the flight plan saved in the right folder, or maybe you are generating an empty plan to begin with? what exactly were the waypoints you were trying to use? maybe they were of a different airac cycle or something (although nat routes usually have a few generic lat/lon points in the middle that should load....)

 

will the FMC allow me to reprogram and execute the flight plan again after pushing back from the gate....during taxi or on the runway?

 

 

you can reprogam the fmc at any time pretty much, in fact it is quite normal if you aren't sure which runway/star to expect on arrival for example.

 

Any suggestions as to a more user friendly "free" navigation utility?

 

 

maybe have a look at simbrief.com ... for popular routes you can see ones people used recently and just use those, might be enough for what you are trying to do. it still needs to be configured (like simroutes) to put the plan in the right spot, etc. 

 

anyway good luck

Instead of using a flightplanner, you can go to Flightaware.com.  It has thousands of RW flight plans, focusing on the U.S. and several other major areas, and includes many long haul plans.  You can just enter them directly on the Route page.

Thank you Mike and Andy for your suggestions.  Mike, Flightaware seems like a utility for actual line pilots and not for flight simulator hobbyists.  Correct me if I'm wrong.....I was somewhat intimidated by the site....other than plugging in an actual airline and flight in real time. I didn't immediately see a section where RW flightplans were available for download for flight simulators. 

 

Andy, I did create a user account at  Simbrief. After entering a departure and desitnation airport ( in this case KEWR -EDDF)  I was given the 5 most recent flightplans.  The most recent was entered into the route box.  When I pressed the analyse button three errors  came up stating invalid endpoints or  airay/fix not found.  What do I do to correct these errors to ensure route contiuity?  Once these issues are corrected and I save the flightplan, does it save it as a PMDG RTE file?  And can I enter it as a company route so that I don't need to enter each waypoint manually?   I'd really prefer to enter the flight plan file name in the company route selector, and have the waypoints automatically load the flight plan.

 

Also I notice that the Airac availalbe is the oldest one on the Airac list.  The newer airacs need to be purchased at Navigraph to unlock them.  It looks like there's a different download for each addon such as PMDG, Captain Sim..etc at Navigraph.   What is the funciton of this download for a given addon?

 

This more sofisticated flight plan generating software is all new to me, so I'm not quite understanding how the various products (ie Simbrief, Navigraph, etc work with each other).  I looked at the Simbrief Youtube tutorial video but it wasn't very intuitive.  My brain is just beginning to evolve from the simplicity of the FSX route generation uitility. 

 

PS...I'm still flying "lone wolf" though the base FSX  ATC.  With PMDG I have created some routes (trhough route finder and sim routes) and saved as PMDG RTE files and FSX PLN routes.  I've loaded the FSX route throught he FSX route utility, then load the "mirror" PMDG route in the FMC.  My last question here is:  Are Navigraph, Simbrief, and Flightaware designed for use with a virtual online ATC Service?

 

Thanks again for your comments and support.

Hi, Tom,

 

Flightaware doesn't have flight plans for direct download, but it does give the flight plans for thousands of real world flights.  Just enter the departure and destination airports and you will see many flights.  Most of them have flight plans in the box at the right.  I was just suggesting that you copy one manually directly into the CDU (screen giving access to the FMC) route page, entering the individual waypoints and airways.  Often they have SIDs (departure procedures) and STARS (arrival procedures) as well.  These need to be entered on the DEP/ARR pages in the CDU.  This would give you a better sense of the components of a flight plan.

 

 

 

This more sofisticated flight plan generating software is all new to me, so I'm not quite understanding how the various products (ie Simbrief, Navigraph, etc work with each other).

 

I'm not familiar w/ SimBrief, although at a brief glance it looks to be very useful.  FSX's database is six or seven years old, so to obtain current navigation data you need to use a service like Navigraph.  If you tried to enter a current flight plan from Flightaware or another up-to-date source, using FSX's flight planner, you would find many waypoints not available.  FSX's approaches are very limited as well as being outdated.  Fortunately, when you save a PMDG or other advanced addon's flight plan in FSX format, it will work pretty well (except FSX's ATC doesn't handle approaches well at all).

 

Most addon makers have their own data format; PMDG has one, Level D 767 has another, Aerosoft A320 has yet another, etc.  So each of these needs to have its own update file format from Navigraph.  Flight planning software programs, including SimBrief, also each have their own.  Navigraph has many formats available, and only charges one rather modest fee per Airac cycle for as many formats as you want.

 

Hope this helps!

Tom, I think you would benefit a lot by actually inputting a flight plan directly in the FMC yourself. You will then understand better what makes up the different elements. Start with a shorter route than a transatlantic one.

 

You can use rouefinder to plan your route, then use the RTE page to input the airways and waypoints. At the bottom of the routefinder page, you will find the entries needed. By using airways and wayoints you do not need to enter every single waypoint, but they will appear in the legs page.

Hi Mike,

 

I wasn't aware that I could save a PMDG RTE file as a FSX PLN file. Do I simply copy the PMDG RTE File from the Flightplan Folder over to the FSX Route folder and change the file type? Or do I need to do somehting else.

Navigraph has many formats available, and only charges one rather modest fee per Airac cycle for as many formats as you want.

 

This makes sense. And I agree the the price to purchase an Airac (or a group) is fairly nominal and reasonable. Once I purhcase and download the resepctive format file, what does this give me in terms of creating / saving a flight plan?  I will have the most current routes and waypoints, obviously.  Will this eliminate any route discontinuity issues?  I suppose I do need to learn to manually load a flight plan on the legs page of the FMC.  But it is so bloddy easy just to enter a flight plan in the company route field, enter the departure and arrival details then push the execute button.  I do have a solid understanding of how the FMC works ( I've deleted legs and updated a flight plan for instance in flight).  I guess I need to be willing to do the more mundane tasks as well as the fun stuff

 

Thanks again for your help

Hi Peter,

 

I would agree with you that I would benefit from manually entering a flight plan into the legs page.  I'll need some form of tutorial to be sure I'm entering the data correctly (or is this fairly intuitive and simple).  As I posted to Mike, I guess I need to be willing to do the more mundane tasks as well as doing the fun stuff like flying and managing the aircraft.  But it is so bloody easy to enter a flight plan into the company route field, enter the departure and arrival details than push the execute buttion! LOL  PS...I find with Routefinder that transatlantic routes are not happening. I keep getting error messages.  Suggestions?

 

Thanks again for your Input. You guys have been great with your comments

The 747 manual as an extensive section on how to enter a route. You enter using the RTE page not the LEGS page.

 

When using routefinder for transatlantic you need to enable NATS in the dropdown box.

Couldn't find a routing between JOHN F KENNEDY INTL (KJFK, KJ) and FRANKFURT MAIN (EDDF, ED) at FL331 - FL390.

 

Possible causes:

  • The system may have failed to find a suitable transition to/from enroute.
  • No airways are linking the departing and arriving places at that altitude range

You may try to:

  • Select a different cruising altitude range
  • Disable SID and/or STAR (the SID/STAR database is not guaranteed to be up-to-date yet)
  • Consult SID charts for departure aerodrome and enter as 'starting fix' the identification if the last fix of a SID procedure
  • Consult STAR charts for the arrival aerodrome and enter as 'ending fix' the identification of the first fix of a STAR procedure

 

PS....I read through the FMC chapter. It is quite extensive. I'll need to go though it a few times....mostly where entering the route is concerned.  Otherwise, I'm famliar with entering everything else from Pos Init, Route page (entering company route), Dep/Arr, sid/stars etc.  Just need to get my head around entering a flight plan correctly with airways, waypoints,  etc.  I believe I read that you can save a manually entered flight plan in the FMC for future use...though I don't recall seeing an explanation on how to do that.

 

Again, thanks a ton!

Hi Mike,

 

OK....I'm starting to get familiar with Flightaware.  I clicked on a flight from LAX to EWR and got the details on the status...and found the flight plan listed. I clicked the "decode" button and got the expanded flight plan below.  The basic flight plan with Airways, and VORS are listed above in boldface. The List below show all the way points, reporting points, VORs....but no airways listed(ps..this acutally shows up as a spreadsheet layout, not a continous string as shown below).  Anyhow, this is where I'm getting a bit fuzzy about entering a flight plan properly.  In the 747 manual, the airwarys (eg  J169) are entered in the VIA field and the various waypoints, VORs..etc are in the TO field. This is where I need a bit of help understanding the correct way to enter the flightplan. Any comments, tips, or direction are appreciated.

 

Thanks again for your support!!  Once I become proficient I'll be more thant happy share my experience with others!

Hi, Tom,

 

First, the plan begins w/ a SID, HOL:TZ9, and ends with a STAR, PHLBO3.  They should be saved for after you have entered the rest of the plan. 

 

There are two ways to enter the plan: using the ROUTE page and using the LEGS page.  The ROUTE page is much easier, and you only need the form of the plan I've copied above.

 

Begin by entering TRM in the right TO column, then on the next line TO column BLH (since there is no airway between them).  Then on the next line enter the airway J169 in the VIA space on the left, and  then KOFFA in the TO blank on the right.   If you now look at the LEGS page you will see that an intermediate waypoint, SALOM, has been filled in automatically.  The next few entries are simply waypoints.  Those go in the TO (right) column.  When you get to further airways, enter them as you did for J169.  After you have finished entering, you can again go to the legs page.  For this plan, you will see that between BKW and GVE several more waypoints will have been automatically entered -- should be all the intermediate waypoints in the long version of your plan.  All of the waypoints in the long version should be listed on the LEGS page, and you could have entered them one by one there.  But the ROUTE page makes entry much simpler.

 

Finally, go to the DEP/ARR page, choose DEP, enter the departure runway and then on the right HOLTZ9, the SID.  Then go to ARR, find the likely arrival runway, select it, then select PHLBO3 (Not all SIDs or STARS are available for all runways, so you may have to pick a different SID or STAR).  You can view U.S. SID and STAR charts, as well as runway final approach charts (IAPs) at flightaware, by selecting a specific airport and then IFR PLATES.  HOLTZ9 appears to be available only for west KLAX departures, while PHLBO3 looks to be available for all EWR runways.

 

I don't own the 747 for FSX, but I'm sure it came w/ at least one tutorial.  You  will get a lot out of following it (or them).

You need the RNAV box checked.

 

You should also tick the boxes for SIDS STARS in routefinder. The reason being that the planner will then create a route that starts at a major intersection which coincides with the endpoint of the usual SIDS. Likewise it will end at a major intersection which coincides with the beginning of the usual STARS. This will enable you to load the route into the FMC, and you can select which departure SID to use once you actually know which runway you will be taking off from, as they are runway specific. Likewise you do not need to enter a STAR until you are closer to your destination and have a better idea which runway you will be landing on.

 

If you untick the boxes for SIDS STARS the flightplan will start/end at waypoints that may not correspond to waypoints in the SID/STAR that you expect to fly.

Mike,

 

Thanks for your input.  You filled in quite a few blanks with your explanation!  I have a pretty good grip on entering flight plan information correctly now. Also, I'm getting a better handle on Simbrief. This is actually a very good utility once you start getting a handle on it. I've generated several flight plans and saved as FSX and RTE files.  However, as you mentioned above, I believe these routes contain SID/STAR fixes. So, I'll need to identify them and change/remove accordingly based on current runway availability.  That said, I'm going to enter a few short flight plans manually as suggested. This will be a good exercise no doubt.

 

Peter,

 

Thanks! I checked the SID/STAR and RNAV boxes. This solve the issue of generating a route in Simroutes.  I then inserted the route into Simbrief...and generated a good route.  Also, I found that with grabbing a RW flight ( ie airline, flight number dep/arr from Flightaware, Simbrief automatically loaded the flight plan for that specific flight. Very cool!..

 

I haven't used the VNAV yet as I've been happy to take FSX's ATC prompts to lead me to my flight plan....at which point I engaged the auto pilot and  LNAV.   Thus I haven't been using sid/stars.  That said, I will work towards using these navigation features now.   We'll see how FSX's ATC behaves with this.

 

Thanks again Gentlemen!  I'll let you know how I progress.

You will find that the default ATC does not know aything about SIDS/STARS. All it knows are waypoints. If the SID/STAR you are following in your 747 FMC differs from the waypoints in your FSX flightplan (they almost inevitibly will), you will get nagged by ATC to follow a different course. You will have to ignore their instructions, until you reach the end of the SID when you should be back in sync. Same with a STAR....if it leads you to line up with the ILS for the runway you will have to ignore any ATC vectors, unless of course you wish to be vectored.

 

There are better ATC addons you can buy, but none are perfect and take a bit of getting used to. I suggest you wait a bit before trying one.

Hello Peter, Mike,

 

Your suggestions have been very helpful. I've successully loaded flight plans manaully. Also, I saved flight plans in FSX and PMDG file formats. I found the Flightaware and Simbrief resources to be quite good.  As mentioned we can get any number of real world/real time flights just by plugging in an airline and departure/destination details.  you can select a flight and get a map of the route. I found that you can grab the route in Flightaware and plug it into Simbrief when creating a new flight.  Interestingly, if you plug in a given airline, flight number, departure and destination, simbrief will automatically load the flight plan into the flight planer. There you can check the validity of the flight against the available AIRAC.  If a waypiont isn't recognized it will tell you so, and you can remove it, and re-check the flight plan.  You'll get the thumbs up when all "errors" are removed.  This is very cool.  

 

Once you added pax weight, cargo weight, and Zero Fuel weight, then  you can file the plan, and get a detailed printed flight plan.  This plan will caclulate fuel burn, contingency fuel, taxi fuel, rerserves, and alternate fuel for you based on the current weather, etc.  

 

The one thing I've noticed with the PMDG FMC is that not all airports have available SIDs.  For intance KEWR (Newark Liberty) and KIAD (Wash. Dulles) don't have any SIDs. When you select a runway for departure, the SIDs column says "None"  As such you don't get the detailed climbout and cruise altitudes and target speeds at each waypoint.  I know you can enter these manually...easily enough.  And the detailed simbrief flight plan gives you target altitudes and air speeds. But the airspeeds seem kind of high. For instance, leaving Dulles (KIAD) the first waypoint is SWANN @ 59NM.  The report says I'll cross this waypoint at FL 237, and Mach .82  TAS 505NM.  This seems awfully fast for the altitude even for the 747-400.  Any comments on this?

 

PS...I did create a flight plan from Honolulu (PHNL) to Newark(KEWR)  PHNL did have SIDs available and I was able to select one and enter the transition waypoint as well.  Once I executed the plan, I got a detailed FL and Airspeed targets for each waypoint along the way. So, my VNAV worked just fine. Also, FYI KEWR did have availabe STARs

 

Any comments about SIDs not being available at certain airports?

 

Anyways....do recommend the resources that you guys mentioned (ie Simbrief and Flightaware. They are quite useful and easy once you get the hang of it).

 

Cheers!

PS.....I just realized that the FL and Air Speed details aren't calculated unit you completed the Fuel load, take off and thrust pages.  So that question is answered.. However this doesn't answer the question about available SIDs

Hi, Tom,

 

Thanks for reporting about SimBrief.  I need to check it out.

 

You should have SIDs and STARs for both KIAD and KEWR.  I've flown the 777 in and out of KIAD recently and they were certainly there.  Take a look in FSX/PMDG/SIDSTARS and find the files called KIAD.txt and KEWR.txt.   As long as you don't edit and save them, opening w/ notepad won't do any harm.   You should see lists of both SIDs and STARs in each file, along w/ the waypoints and other data such as speed and altitude restrictions under each named SID/STAR.  If they are missing perhaps you have an old Airac.  Current number, just released, is 1503.  (The FMC should show you the Airac number and date; also each [airportID].txt file should give the Airac number and dates near the top.)  If they are there I'm not sure why your FMC would not see them (except that some SIDs/STARs are limited to certain runways; once you select a runway some may disappear for this reason). 

 

Some airports do not have SIDs and/or STARs.  KORD only has STARs. All departures are vectored.  KMOB, where I live, has neither (not all that much traffic).   You can check the IFR plates on flightaware -- if an airport shows as having charts for SIDs and STARs, they should show up pretty much the same in your FMC.

One top tip for Simbrief users -- the PMDG 747 burns quite a lot more fuel than the real thing. It's not quite consistent across the flight regime which maks it quite difficult to compensate completely accuratelt, but I find that using a fuel bias of P08 works well in general. As a very, very rough TLAR (That Looks About Right) cross-check for your figures, I usually assume a burn of around 12T per hour (for comparison, the real thing is much closer to 10T per hour).

 

On that subject, I find Simbrief to be largely accurate as far as the flight profile predictions are concerned -- top of climb and descent are never going to be exact but I find they are close enough for the fuel predictions to be pretty accurate once the P08 bias factor is applied, which is really the main thing. I also find that the initial optimum altitude and subsequent step climbs are pretty close as well. There are some inaccuracies in the PMDG 747 flight model -- for instance, the real thing climbs quite a bit better and burns less fuel overall -- which pose challenges for any flight planning software, but on the whole it's good enough.

Hello Simon,

 

Thanks for the Tip. I will use fuel bias P08 and see how that goes. The fuel burn rule of thumb ( ie 12T/hr) is good to know.  I'll run with this.

 

Mike,

 

I still can't quite figure out why I'm not getting any SIDs for Newark or Dulles.  I haven't purchased the most recent AIRAC yet.  However with Simbrief, you can remove waypoints that earlier AIRACs don't recognize. I'd think that earlier SIDs should be in the PMDG FMC database.  Puzzling for sure.  I'll check the files you mentioned though

 

Thanks Gents,

 

Cheers
