IFR Practice Approach CTAF Communications

[martymayes]

Hello, please help settle a friendly hangar argument about CTAF location announcement best practices surrounding IFR practice approach communications arriving at an uncontrolled airport?

1st pilot broadcasts on CTAF airplane location referencing distance & direction from IFR navaids (ex: at Arket inbound VOR 12 approach);
2nd pilot broadcasts on CTAF airplane locations referencing distance & direction from airport (ex: 5 mi west inbound Rwy12 low approach).

Airport & plate referenced is KLVN VOR 12.

I looked in the AIM for IFR vs. VFR CTAF lingo but was unable to locate best practice guidance. Thank you for your help.

There is guidance in the AIM for this exact subject, para 4-1-9 (g)(4).

There is also an Advisory Circular pertinent to this subject, https://www.faa.gov/documentlibrary/.../ac_90-66b.pdf
