Does an "IFR approved" GPS placard require database updates?
In article ,
Peter wrote: I've been told that if one's GPS is an IFR approved unit (KLN94B in my case) and it's not placarded "VFR only" then I am required to have the latest database, otherwise I am not complying with the minimum equipment list (in ANY flight) - is this correct? I would think that if a database update was required and the unit displayed an appropriate message wrt the database validity, then that would satisfy any placard requirement. Does your aircraft have an MEL? If so, what would this mean for the validity of insurance? You'd have to find out from your insurance company. -- Bob Noel no one likes an educated mule |

During my instrument training I was told that if you have an IFR
certified GPS, it had to be updated if you were using it for IFR Flight. You can use it VFR even if it hasn't been updated Charlie Peter wrote: I've been told that if one's GPS is an IFR approved unit (KLN94B in my case) and it's not placarded "VFR only" then I am required to have the latest database, otherwise I am not complying with the minimum equipment list (in ANY flight) - is this correct?

You need to read the flight manual supplement for your aircraft. Different installations have different reqirements. It's doubtful that "MEL" applies at all here since your plane most likely doesn't have one. As far as non-IFR flight, nobody suggests ripping the alitmeter out of my plane because my IFR certs have expired. |

Exactly... Using it for an IFR GPS is all about the POH supplement.
Garmin requires updates. UPSAT did not - just required that you verify that the approach hasn't changed. None of this prevents you from using the GPS, of course, for enroute VFR use. Now some years ago there was a controversy started by Flying magazine because of the speculation that an over zealous FAA inspector might view an out of date database as a violation. But the FAA clarified that this was not the case. Same deal as with outdated charts in the plane. Perfectly okay... But you MUST have the current information you need to complete the flight safely. That same outdated chart (or database) won't get you out of jail if you violate some airspace (or worse, violate the terrain). |

You can use an expired database GPS for all the VFR you want. But to use it for IFR, you first have to confirm the database information for any approach you'll use hasn't changed. Or you have to manually chage it in the database if it has changed. Unless precluded by the flight manual supplement or, if incorporated by reference like "Must be operated in accordance with the owners manual" in the supplement, the users guide. The KLN89B and KLN94 are apparently two such units - their supplement introduction states "NOTE: A current database is required by regulation in order to use the (blah) GPS system for non-precision approaches". The KLN94 limitations page states "Instrument approaches must be accomplished in accordance with approved instrument approach procedures that are retrieved from the KLN 94 database. The KLN 94 aeronautical database must incorporate the current update cycle." The 89B's limitations page is similar, except they also have a minimum software revision limitation. Doesn't look to have any discretion to verify and go with expired databases with these boxes at least. |

Minus the words "by regulation," my Garmin GNS430 GPS also has such as restriction in the POH supplement. I recall reading here that at least one other GNS430 owner did not have such a restriction in his supplement. One possible explanation may be that my unit, as purchased by the previous owner of the aircraft, was one of the first GNS430s available. Perhaps Garmin and/or the FAA loosened that restriction as time went on. -- Peter ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

The Supplemental POH is approved on an installation by installation basis, so there is technically no general answer, except RTFM for your airplane. In practice, the GPS manufacturer provides a boilerplate SPOH, so that's what gets sent into OK City for approval. Dave |
