I see a change here. The procedure turn is NOW required IF a course reversal is necessary. If you are straight in, or nearly so, but NOT on radar vectors there is no longer any regulatory requirement to do a procedure turn. What regulation was changed? It seems to me that only the AIM was changed; I'm not aware of any regulatory changes. Ron (EPM) (N5843Q, Mooney M20E) (CP, ASEL, ASES, IA) |

"150flivver" wrote in message ups.com... This was discussed on the AOPA's board. The FAA did not intend to change the meaning--it was supposed to be a clarification. The procedure turn remains required even if your course happenes to be aligned with the inbound course unless the symbol "No PT" is shown, when RADAR VECTORING to the final approach course is provided, when conducting a timed approach, or when the procedure turn is not authorized. What makes the procedure turn required? I'd ask the controller for permission to proceed inbound sans procedure turn if that's what I wanted to do. What difference would that make? It's either required or it isn't, the controller can't override the FARs. |

What FAR states when a procedure turn is required? Point taken, Mr. Socrates. You could ask for a vector. A vector to where? The FAC? Aren't you already on it? A vector to the FAC. The poster to whom I responded didn't say whether he was aligned on the FAC. He just suggested that one could ask the controller's permission to skip the PT. I suggested that one could instead ask for a VTF, so that the condition for skipping the PT would be met. |

A procedure turn is the maneuver prescribed to perform a course reversal to establish the aircraft inbound on an intermediate or final approach course. The procedure turn or hold in lieu of procedure turn is a required maneuver (the following text is underlined in the AIM) when it is necessary to perform a course reversal. The procedure turn is not required when the symbol "No PT" is shown, when RADAR VECTORING to the final approach course is provided, when conducting a timed approach, or when the procedure turn is not authorized. The new text strikes me as entirely ambiguous. It could mean: "The procedure turn is a required maneuver, unless one of the following conditions obtains, in which case a course reversal is unnecessary: 1) the symbol 'NoPT' is shown; 2) radar vectoring to the final approach course is provided; 3) you are conducting a timed approach; or 4) the procedure turn is not authorized." Or it could mean: "The procedure turn is a required maneuver, unless: 1) the symbol 'NoPT' is shown; 2) radar vectoring to the final approach course is provided; 3) you are conducting a timed approach; or 4) the procedure turn is not authorized; or 5) there is (for any reason) no necessity to perform a course reversal." The two interpretations differ if conditions 1-4 don't obtain, but the pilot (and/or controller) thinks there's no need for a course reversal. The first interpretation says the procedure turn is still required in that case; the second one says the opposite. As a previous poster noted, they need to define how many degrees of turn constitutes a "course reversal". Then it would clear and unambiguous. Otherwise it is still is open to interpretation depending on the aircraft/speed etc. |

As a previous poster noted, they need to define how many degrees of turn constitutes a "course reversal". This is defined; in the TERPS. More than 30 degrees or more than 300' and a procedure turn is needed (IIRC). However, this just gives the procedure designer what they need to design the procedures. The pilot needs to use the published procedure. Then it would clear and unambiguous. Otherwise it is still is open to interpretation depending on the aircraft/speed etc. -- Mark Hansen, PP-ASEL, Instrument Airplane Sacramento, CA |

If he wasn't already on it, and if a vector to it was an option, it'd probably be issued without his asking for it. |

I'm a brand new instrument pilot, but I read this kind of thing for a
living, so my opinion may not be realistic, just legalistic, but here goes: A procedure turn is the maneuver prescribed when it is necessary to perform a course reversal to establish the aircraft inbound on an intermediate or final approach course means that if you need to perform a course reversal, you need to do a PT. Otherwise, you don't. The following language: The procedure turn is not required when the symbol "No PT" is shown, when RADAR VECTORING to the final approach course is provided, when conducting a timed approach, or when the procedure turn is not authorized. lists some exceptions, but doesn't change the first requirement which means that even if you need to do a course reversal, you don't have to do a PT if one of these exceptions applies.It doesn't mean that you need to do a PT unless one of the exceptions applies, the original definition still applies, no course reversal, no PT. I didn't look up the definition of course reversal. This makes sense to me at least in the following case, if you are inbound from the opposite direction, and receiving radar vectors, you would normally need to do a course reversal, so a PT would be required, but ATC will vector you around to the final approach course usually sort of rectangularly. Since this is a listed exception, you don't need to do a PT. If you weren't getting vectors, or one of the other exceptions didn't apply, then a PT would be required. If you are inbound on a course that doesn't require a course reversal, no PT is required even if none of the exceptions applies. Brad wrote in message nk.net... rps wrote: Doesn't the underlining just mean that the text was added? I guess the FAA is just stating the obvious: you don't need to do a PT when you're already inbound. That's not what they are saying at all. You could be inbound yet not have arrived via a vector to final, a timed approach, or a NoPT route. Usually, that would mean that you're too high to go straight-in, at least by the standards used in TERPS for descent gradients. |

Otherwise it is still is open to interpretation depending on the aircraft/speed etc. No, the ambiguity I'm pointing out isn't just a matter of the vagueness of "course reversal". The new AIM phrasing is ambiguous as to whether the enumerated conditions are meant only as an *elaboration* of what it means for a course reversal to be unnecessary (in which case a charted PT is required unless the enumerated conditions are met), or whether a lack of need for a course-reversal is meant as an *addition* to the enumerated conditions (in which case the PT might not be required even if none of the enumerated conditions are met). A secondary point (mentioned earlier in the thread) is that the TERPS standards can require a PT on the basis of altitude, even if you're already aligned with the final approach course. Moreover, it would make little sense for the AIM to recapitulate the TERPS criteria for PTs in order to specify the required action by pilots. Instead, the procedure chart itself should be designed according to the TERPS criteria, and should specify a PT requirement (by omitting the 'NoPT' designation) whenever those criteria are met. The first interpretation above would be consistent with that intent. --Gary |

I think what you are missing is that the determination as to whether or not a course reversal is required has to do with the verbiage on the FAA forms that define the SIAP (standard instrument approach procedure) and not on what you as the pilot might determine at the time you are executing the approach. The FAA forms (8260 series) are (mostly) based on TERPs and those approaches are incorporated by reference into 14 CFR 97.20(b), making the procedures regulatory (refer back to 14 CFR 91.175(a)).
