Commencing an approach at an IF with a procedure turn

Asked by: 891 views FAA Regulations, General Aviation, Instrument Rating

I’m a controller at ZLA and I recently got into a debate about an approach at KDAG. 
The question is whether or not an approach clearance for the RNAV Rwy 26 can be issued from BASAL (a feeder fix to the IF). On the chart basal is identified as a feeder fix to the IF (DOGSE). It is more than 90 degrees but DOGSE has a HILPT. However I cannot find a regulation that specifies that the approach can begin at an IF where it is more than 90 degrees. Could this be a chart error and DOGSE should in fact be identified as an IF/IAF? Or is there a reg someone could direct me to that allows this clearance to be issued. Thanks.

    I’m not sure what you are asking.

    Are you asking whether you can issue a straight in clearance from BASAL, avoiding the HILO, instead making a 200 degree turn and diving the 3100 feet to ZABSA in only 3.8 nm? No.

    OTOH, if you are asking if the lack of an IAF notation at DOGSE is a charting error, yes. The regulatory source document for the approach describes it as an IAF for the hold. Those types of errors, while not that common, are nor unusual.

    I would suggest you report the charting error of the missing IAF. Here is a link https://www.faa.gov/air_traffic/flight_info/aeronav/aero_data/Aeronautical_Inquiries/
