VNAV is not calculating

vnav_zps792f6625.jpgGood morning,

 

I have developed a new problem that seems to only exist on the 737-700. As I enter a flight plan as I have always done, it does not appear to be calculating my VNAV rate of ascent to my cruise altitude. I have done multiple plans and restarted FS after my entry. Any ideas?

Did you execute the PERF INIT page?

 

Would be my first guess too.

 

Either that or you've found a route that trips up the solver somehow. If there's a bunch of complicated block restrictions and stuff it could be that.

Its executed yes. For giggles I loaded the 737-800 and the plan was entered perfectly. Not sure why it is only on the 737-700.

 

**EDIT** It would seem that the problem is isolated to the KIAD airport at this time. I was able to load a plan from KTUS to KSAN and all my numbers were in. KIAD to KDEN failed. Weird right?

Can you share the exact plan so we can try to reproduce it? I fly -700 a lot and have never seen a problem like this.

 

Did you enter runway?

Yes I entered the runway.

Looking at the JAGGR2, it looks like that one could maybe trip the VNAV up.. Try that same route but use the DANND7 instead. If it works ok, then the arrival is the problem.

Ill look at that Steve, I was able to do the flight using the 737-800 though which is beyond odd that one version would do it and the other would not.
