So here is the issue, I show up for my 141 School end of course check ride today for my IR and was told I would only be able to complete the Oral part of the test because my long x-country did not meet the qualifications of requirement. So we depart IFR flight plan with the miles requirement met no issue. Here are the approaches: Depart KCMA- ILS 25 into KVIS full procedure with ARC Depart KVIS WEESL1 arrival for LOC8 @ KBUR Depart KBUR via the SID and shoot RNAV Y 26 at KCMA It was explained to me that this was not acceptable via the FAR's There's an FAA letter of interpretation1 [A] pilot may choose any three of the following navigation systems: Non-directional beacon (NDB) Localizer-type directional aid (LDA) Very high frequency omni-range station (VOR) Global Positioning System (GPS) Simplified Direction Facility (SDF) Instrument landing system localizer (LOC) So I guess I am just super confused as to why this would be, what would you do without a GPS? Its a 1,500 hundred dollar mistake if so and should that really fall on me being a IFR student? Thoughts please.
