Hi guys,I wonder about something I am sure alot of you have the answer to, it's just something I can't figure out for myself...When i choose a STAR for the landing airport, the FMC nearly always takes me down all the way to the selected runway. Even if i can select transition.So my question is: When do I choose a transition? And how can I see that i need or don't need to select a transition?Reading back now, I see that i ask the same question twice :)Thanks in advance!

The transition determines how you enter (STAR) or exit (SID) the procedure. Some procedures will have multiple transitions available. If you are arriving from the east, you don't want a transition which takes you west of the field, for example.

Hi Caballero, Trevor is 100% regarding STAR transitions. However, if I read your question correctly it was regarding the necessity of selecting approach transitions when flying a STAR. Approach transitions are used either when you are not using a STAR or when your approach transition is also a waypoint on your STAR. You don't see pilots flying STARs almost to the airport then U-turning and heading all the way back out to intercept an approach transition. The answer lies in ATC proceedures. Many times you will not recieve both STAR and approach clearances from the same ATC controller. The approach controller may assign a different STAR than filed, completely negate a STAR and vector you to an approach transition or other waypoint, or just assign headings all the way to final. In short, use your best judgement within fsx. If a STAR/STAR trans and approach/app trans are "on your way", fly them. Otherwise forgo the app trans and just use the STAR and approach. *****Others may feel free to correct content, I'm eager to learn******* Happy flying-Nathan Jaeb

Thanks for the reply, guys!Peter
