IFR use of handheld GPS
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. This seems fairly clear to me..... Shh...don't let the facts get in the way of ones mindset. A primary reason that handheld/VFR GPS units are not acceptable for VFR use is that they not not include an integrity capability. That is essential for IFR ops. Ron Lee |

As far as I can tell, the advisory circular that the "fact" supposedly came from was paraphrased by some written test preparation materials. That is what you quoted. Not fact. See the original message from Dane. Neither the AC nor POHs say anything about handhelds. |

Ron Lee Sure, sounds good, but then if the FAA regulated by reason, NDB approaches would have been made illegal long ago. I would bet many more people have been injured and killed because of crappy ADFs and just plain inaccurate old technology than by using a handheld GPS unit while flying enroute. Even VORs don't have much for "integrity monitoring," just that dumb little flag. I've seen many inaccurate VOR readings and some outright failures without the flag showing red. I've also seen handheld GPSs fail, too. But, in general, they are probably more accurate and dependable than VOR and ADF. Peter |

This is like a religion with you people. It's strictly a matter faith that use of handheld GPS during IFR enroute flight in US controlled airspace is illegal and/or unsafe. |

A handheld GPS and a ham sandwich are both useful objects, but using either one for the other's intended purpose can be dangerous. |

Well, there are those stories of the open-cockpit airmail pilots using cigars to time approaches. Don't know about ham sandwiches though. I suppose if you're Steve Fossett, and your sandwich starts getting moldy, you're about to run outa gas. |

See the original message from Dane. Neither the AC nor POHs say anything about handhelds. Section 1-1-19-d of the AIM addresses the general requirements for conducting any GPS operations under IFR. Section 1-1-19-d1a explicitly states (and I quote): "Visual flight rules (VFR) and hand-held GPS systems are not authorized for IFR navigation, instrument approaches, or as a principal instrument flight reference." It appears that the Gleim written test prep materials I cited in my previous posting took much of their material from the AIM and not the AC. The AIM, however, also does cite AC 20-138. Again, this seems fairly clear to me. -- Dane |
