RNAV (GPS) Approach NoPT Confusion

Asked by: 3730 views , ,

The RNAV (GPS) Z RWY 19R at Concord CA (KCCR) has been a source of confusion. Link to the approach: Concord GPS 19R Z For example, if flying the full approach, own nav, how do you join the approach if coming from the south or west without making a Procedure Turn? The depicted hold is for arrivals and must be assigned by ATC. It is also the missed approach hold, but it is not part of the approach (thin line hold). Are you expected to fly at the MSA of 5,100 or higher and make your way to the IAF while staying within the 25 mile MSA? Isn't the goal to join the approach with maximum 90 degree turns? One more thing: This approach only has LPV minimums. If near the FAF and your GPS WAAS check fails and you get LNAV annunciation I assume you must go missed at that point and fly all the way to the MAP at 1,300 feet, then execute the missed procedure. Concord also has the 19R Y, which is the LNAV version of this approach and is almost identical, except for a slight difference in the missed instructions. Could you legally swap out one approach for the other if you had to finish it LNAV? Thanks

    The MSA 5100 MSL has no operational use on this approach. It may only be used in the case of an emergency. If cleared to REJOY along a magnetic track between 156 and 336, the turn to the 246 degree magnetic course will be 90 degrees or less and the hold would not be needed. If on the other half of the compass, you would either request the arrival hold or it would be assigned to you.

    You can also be vectored to final or vectored to a point that direct to FEVTA does not require a turn to exceed 90 degrees to the FAC.

    This approach can’t downgrade to LNAV, so it will downgrade to TERM or MAPR and you will need to fly the missed approach. You were cleared for the RNAV Z RWY 19R and not for the RNAV Y RWY 19R, so you are not authorized to fly it in lieu of the Z. You need a new clearance and probably a vector or back to the MAPH and hold at REJOY where you can request the Y.
