PIC FMC Question for Radar Contact

Featured Replies

Hi All,Just completed a flight from Denver to LAX, when Radar contact clears you to decend to your initial contact point, as in this flight..Expect to cross 40 miles of FUELR at 10000 and 250 knots, How do you program the FMC in 767 PIC to do this??? Man I have tried every thing. Ended up missing the altitude clearance and it started the down fall of my flight.Also is their any way for Radar contact to recognize that you are flying a STAR (CIVET4)so it does not vector you all over the place, as it did me sending me over the Pacific ocean when I was to land on 24L, Heck I never did get to the airport.Any help is appreciated,Thanks,Dale Reitz

Hi AllNo need to reply, found the procedure in the 767 PIC FMC Manual.

Ok, According to the 767 PIC FMC Manual page 45, When RC gave me the clearance to cross 40 miles from FUELR @ 10000 and 240 kts, I should of made a new waypoint before FUELR as follows.Select waypoint FUELR on the FMC to place it on the scratch pad, then using the scratch pad place /40 so that the scratch pad contains FUELR/40 then press the #1 LSK to enter the along track waypoint into the route.Then selected this new waypoint and enter my speed & altitude and Executed the new waypoint in the #1 LSK (Line Select Key) and then hit the Execute button on the FMC.I would have been way too low 40 miles from FUELR which would of placed me around 65 miles from LAX at 10000 feet. From now on, will be selecting a way point as close to the field as I can even if it is not part of the Arrival Procedure.If anyone has a better Idea on how to do this PLEASE let me know.Thanks

Greetings.If I read the RC documentation correctly, if possible the last waypoint of your flightplan should be colocated with the airport. Heading into LAX, for example, I'd use LAX KLAX as the last two waypoints. Flying into KBOS I use BOS KBOS as my last two waypoints. You'll get a crossing restriction of 10k/250 knots 40 NM from . That would then put you where you'd like to be (10k 40 miles from the field).As for doing this in PIC (or in real life from what I read), yes, you could (if you wanted to use VNAV instead of FL CH) insert a waypoint via the above procedure (personally, I use /-40 instead of just /40 - I guess the FMC is intelligent enough to know you mean 40nm before waypoint since you're going to insert the scratchpad entry before the waypoint in question.. Also, the waypoint does have to exist in your legs page (I mean you can't just pick a random waypoint not already in your plan and insert it via /+-) before this trick will let you add the conditional waypoint. You could also use the FIX page to insert a waypoint on your ND (doesn't have to exist in your legs page), have it draw a ring 40nm from it, dial 10k on your MCP and use V/S to make Kermit the Green Arc cross the line if you were so massochistic as to do the math, speed, descent rate, and restriction compliance calculations all in your head instead of letting the automation do it for you.Personally, I always create my flightplans for export to RC/FS2K, and then after importing them to the PIC FMC (or PSS, or DF, whatever reasonably accurate FMC equipped aircraft you want, actually,) or just manually entering them into the FMC RTE page using airways, whatever method gets the waypoints into the LEGS page - I then go insert a waypoint of with a crossing restriction of 250/10000 before I even take off and save the plan for use in that FMC. That way once I do get to the point where RC clears me to descend, I can just hit DES NOW from the FMC, or dial the lower altitude in the MCP (if VNAV wanted to start down earlier), and either way just let VNAV do it's thing.Take care!P
