Non-precision Approaches
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with performing non-precision approach procedures. Note: See Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Bottom line
RNAV approaches without approved vertical guidance and conventional NPAs should be flown, whenever possible, using a CDFA technique.
