January 17Jan 17 Random question here. My home airport is Providence, RI (KPVD) and I fly into quite a bit with the Fenix and iFly. The standard STAR for Providence when coming up the coast is the JORDN2 arrival. It's a very simple STAR, pretty much just hit waypoint JORDN at 11,000' and you have one other waypoint and that's it. Question is - in both the Fenix and iFly, when using that STAR, the FCM has me much higher at JORDN, typically around 17,000' which doesn't give me much time to descend to the correct approach altitude. I can easily overide this in the FMC but I'm just curious why both aircraft don't reflect the hard limit that is shown in the STAR? Is this a glitch or is this accurate RL behavior?

Perhaps has something to do with programming the FMC/MCDU for that STAR and transition. In a scenario landing for RWY 5, at JORDAN, it is "expected to cross at 11000" not a hard altitude, so the FMC/MCDU is looking ahead to find a hard altitude. In our case, the next hard altitude is at CUTSI (2000 ft), and along that STAR, with the transition, we really have no other mandatory crossing ATC restrictions. So, when the T/D is computed for an "idle" descent, your altitude might vary above JORDAN due to other factors. In my case, in reference to aircraft loads and weather conditions for RWY 5, IT DID COMPUTE 13,500, and for RWY 23, with PVD transition, it was FL210, my CRZ ALT. Now, if you want to cross JORDAN at 11000, just put a hard altitude at that point. 747 Captain for the last 39 years, and still learning.
