d. For RNAV-equipped aircraft operating on unpublished routes, issue approach clearance for conventional or RNAV SIAP only after the aircraft is:
1. Established on a heading or course direct to the IAF at an intercept angle not greater than 90 degrees and is assigned an altitude in accordance with b2. Radar monitoring is required for RNAV (RNP) approaches when no procedure turn or hold-in-lieu of procedure turn will be executed.
2.Established on a heading or course direct to the IF at an angle not greater than 90 degrees, provided the following conditions are met:
(a) Assign an altitude in accordance with b2 that will permit a normal descent to the FAF.
NOTE- Controllers should expect aircraft to descend at approximately 150-300 feet per nautical mile when applying guidance in subpara d2(a).
(b) Radar monitoring is provided to the IF.
(c) The SIAP must identify the intermediate fix with the letters “IF.”
(d) For procedures where an IAF is published, the pilot is advised to expect clearance to the IF at least 5 miles from the fix.
3. Established on a heading or course direct to a fix between the IF and FAF, in accordance with Paragraph 5-9-1, Vectors to Final Approach Course, and Paragraph 5-9-2, Final Approach Course Interception.
