load in a route and where origin and dest appears the flightplan shows within this area

---

Are these routes that you saved using the 737 FMC/CDU?

no this route I downloaded from Simbrief and then from the FMC loaded it in via saved flightplans

The jet airways are not included, so all waypoints are DIRECT, and, AFAIK, neither are Speed/Altitude Constraints included.

If I use a 3rd party flight planner, I use it only to provide the jetways, SIDs, and STAR/App, info, and I do the programing in the 737's CDU.

Well how odd your 757 and 767 do so why not the 737-300

FMC 737 is fully compatible with routes created in the 767/757, you can use routes created by 57 67 in the 737.
FMC 37/57/67 also supports importing airways from Prepar3D/FSX flight plan.

In this short 3 min video showed how to create a flight simulator flight plan, import it into the 737 FMC with the airways, add SID and STAR, and save it in the native Captain Sim route format (saved file EGKKEIDW.rt is located in p3dv4\Captain_Sim\737-classic\routes).
Sorry, no mouse pointer on video.

This video also shows that there are no problems with DEP/ARR, or I do not know how to see it.
