IFR use of handheld GPS

IFR use of handheld GPS
"Sam Spade" wrote in message news:Wip7g.175615$bm6.36868@fed1read04... You are either stupid or stubborn, or perhaps both. I am neither. The AIM reference is explanatory. The AIM is not regulatory. The 8260-16, when describing Federal Airwaty V-XXX, which is formed by VOR facilities, is regulatory. Irrelevant to the subject under discussion. |

IFR use of handheld GPS
"Sam Spade" wrote in message news:Cjp7g.175616$bm6.42955@fed1read04... Not so. You just can't read with any objectivity. Are service volumes based on AGL or MSL altitudes? |

IFR use of handheld GPS
"Steven P. McNicoll" wrote in message k.net... "Dane Spearing" wrote in message ... So, the initial purpose of this thread was to discuss whether or not one could use a handheld GPS for IFR navigation. Lots of people have been tossing around lots of opinions with little or no references to rules or guidance to back them up (hardly surprising...this is usenet after all...) Anyway, for my own personal edification and enlightenment, I went and tracked down the official FAA Advisory Circular that specifies what the requirements are for the use of GPS under IFR. It's entitled "Airworthiness Approval of Navigation or Flight Management Systems Integrating Multiple Navigation Sensors", and is FAA AC 20-130A. It's about as exciting to read as the dictionary (again, hardly surprising). However, the Gleim Instrument Pilot Flight Manueuvers and Practical Test Prep guide (which is where I found the reference in the first place) does a nice job of summarizing the requirements for use of GPS under IFR as specified in AC 20-130A. It states: Authorization to conduct any GPS operation under IFR requires that: a) GPS navigation equipment used must be FAA-approved and the installation must be done in accordance with FAA requirements i) Approval for the use of the GPS for IFR operations, and any limitations, will be found in the airplane's POH (also called the FAA-approved Airplane Flight Manual) and the airplane's logbook ii) VFR and hand-held GPS systems are not authorized for IFR navigation, for instrument approaches, or as a principle instrument flight references. During IFR operations, they may be considered only an aid to situational awareness. Aircraft using GPS navigation equipment under IFR must be equipped with an approved and operational alternate means of navigation appropriate to the flight. a) Active monitoring of the alternative navigation equipment is not required if the GPS receiver uses RAIM for integrity monitoring. b) Active monitoring of the alternative navigation equipment is required when the RAIM capability of the GPS equipment is lost. This seems fairly clear to me..... Did you read the first paragraph of AC 20-130A? The third sentence is most revealing: 1. PURPOSE. This advisory circular (AC) establishes an acceptable means, but not the only means, of obtaining airworthiness approval of multi-sensor navigation or flight management systems (hereafter referred to as multi-sensor equipment) integrating data from multiple navigation sensors for use as a navigation system for oceanic and remote, domestic en route, terminal, and non-precision instrument approach [except localizer, localizer directional aid (LDA) and simplified directional facility (SDF)] operations. This document does not address systems incorporating differential GPS capability. Like all advisory material, this AC is not mandatory and does not constitute a requirement. As such, the terms "shall" and "must" used in this AC pertain to an applicant who chooses to follow the method presented. The criteria of AC 90-45A, Approval of Area Navigation Systems for Use in the U.S. National Airspace System, does not apply to certification of equipment described in this AC. This AC supersedes previous GPS installation guidance contained in: FAA Notice 8110.48, Airworthiness Approval of Navigation or Flight Management Systems Integrating Multiple Navigation Sensors, and FAA Interim Guidance Memoranda dated February 25, 1991; April 5, 1991; March 20, 1992; July 20, 1992; and September 21, 1993. The appropriate information contained in those documents is incorporated in this AC. Here's another little gem from the Advisory Circular Checklist, AC No. 00-2.15: 3. Explanation of the AC system. The FAA issues advisory circulars to inform the aviation public in a systematic way of non-regulatory material. Unless incorporated into a regulation by reference, the contents of an advisory circular are not binding on the public. Advisory circulars are issued in a numbered-subject system corresponding to the subject areas of the Federal Aviation Regulations (FAR) (Title 14, Code of Federal Regulations, Chapter I, Federal Aviation Administration); and Chapter III, Commercial Space Transportation, Federal Aviation Administration, Department of Transportation, Parts 400-450. An AC is issued to provide guidance and information in a designated subject area or to show a method acceptable to the Administrator for complying with a related Federal Aviation Regulation. Its amazing the things one can learn if one actually knows how to read. Perhaps a reading and writing test should be part of the basic pilot's license? |

IFR use of handheld GPS

Where is your reference that GPS is primary for sole means en route navigation? I don't need one. The burden of proof is on those that claim it's use is prohibited. It's up to them to cite the FAR that prohibits such use. That is a giant load of crap. It seems like a basic tenet of the law to me. Where did you learn how to follow rules that don't exist? |

Is it your position that everything is illegal until a law is enacted making some activity legal? I've seen this leap of illogic before. It us usually uttered by a desperate man who finds himself argued into a corner and is beginning to realize that his own prejudices, opinions, feelings and beliefs do not have the force of law. Next you might hear him try to claim that it has the force of law because "that's the way we have always done it". |

Being able to read, speak, write, and understand the English language is a requirement, apparently it's just assumed that applicants meet it. |

IFR use of handheld GPS - everyone brace yourselves... here comes Sam's foul mouth
"Sam Spade" wrote in message news:Pkp7g.175618$bm6.124940@fed1read04... And, it's Stevie's assertion. ...That is pure bull****.... ...You are either stupid or stubborn... Sam, does your mother wash your mouth out with soap when you try and use that language in front of her? Are you losing your grip, Sam? Perhaps you should take some valium and relax a bit before you attempt to continue this legal discussion as you are clearly overwhelmed by those who disagree with you? |
