Post subject: | STAR Selection |
I'm confused as to how the STAR and landing runway are being chosen by PF3. I'll use my previous flight (KATL-KSEA) as an example. When inputting the STAR name into PF3 (in this case it was CHINS3), I alter it so I know which runway I'm being assigned to (so I change CHINS3 to CHINS6R for 16R for example). As I approach PDT VOR where I transition into the STAR, ATC clears me to fly CHINS4L for runway 34L. As I reach the end of the waypoints in my .PLN file, ATC then clears me to final for runway 16R. This is where I'm confused as to why I was given a STAR for a completely different runway to the one I'm landing on. I use the ActiveSky Next weather engine, and this situation happens with and without the ATC wind lock activated and approach downloads suppression activated. I understand that without the wind lock, the runway selection can vary. In this flight however, I monitored the wind at KSEA throughout the flight and particularly leading up to the transition into the STAR, and it remained a decent headwind up the 16's so I'm wondering why I was given a STAR for 34L. Am I missing something that I should be doing? I've included my logs folder. |

When you crossed PDT (start of your STAR), this is what the log shows:
As you neared the last waypoint of your flight plan the log shows: I don't use Active Sky Next, but the STAR transition in this case is 175 miles from the airport. I found some info that indicates the ATC Wind Lock option allows the wind to be reset when you are 80 nm from the airport, and I think preventing downloads on approach applies only when you are close to the airport. One thing you can try is getting a PF3 ACARS ATIS report (see the User Guide) as you get closer to the airport, to check the conditions. Another thing to try (if you want) is designating a closer waypoint as your start of STAR. In the US and Canada the STAR transitions are in some cases 200 or even 300 miles from the airport. |

Thank you for your reply, I didn't know the wind changed at all during the flight with that option enabled. I'll try setting a range ring of about 70nm from the destination and get a weather report then |
