Coming from the SW on the RNAV RWY 15 KONO, how do I align myself with the final approach course? There is only one IAF and no published course reversal. Is it up to me how I get established inbound? [RNAV 15]
It's a RNAV approach. You just fly to PIYID waypoint and that's all. I think all those reversals very useful when there was no RNAV and there was no other reliable way to establish on the final approach course unless you had VOR's and NDB's not at the airport to assist with that. Now it does not make sense. Why to fly more miles if you can fly this approach as published directly.
There are 3 real life situations:
- If you fly commercially you will have a flight plan that will end at PIYID.
- If you just fly somewhere and ask tower for the approach you will get direct to PIYID.
- If it is uncontrolled airport probably it will make sense to go directly to PIYID... or other waypoint.
"Approach, (callsign) request 3 mile offset to the west at CEYTA for alignment."
The offset you request will be what is necessary to execute a roughly 180 deg turn to the inbound course. Keep it snug, but don't cheat yourself out of the space needed to make a comfortable turn in IMC with a little bit of wings level time before you hit the fix.
ATC knows you can't get there and pivot in place, and are usually very accommodating if it is clear what you are asking.
