IFR with a VFR GPS

There is no risk. Anyone that says there is a risk in the use of a handheld GPS for IFR enroute navigation in US controlled airspace is not a real safety expert with actual knowledge of aviation. Steven, when then are handheld GPS units not allowed to be used for IFR navigation? You can do as you wish. Darwinism works well in aviation as in other endeavors. Ron Lee |

Darwinism works well in aviation as in other endeavors. That sounds like you do believe there is a risk in the use of a handheld GPS for IFR enroute navigation in US controlled airspace. Please identify that risk. |

IFR with a VFR GPS
I think the lack of certified mounting is what makes VFR GPS a backup
for flight in IMC, rather than a primary. Note that an IFR GPS includes installation in it's design. They are installed to be part of the scan. There may be VFR installations that are indeed in the scan and convenient enough to use, but the typical VFR installation is lacking in this department. I have a King KLN90B in the panel and a Garmin 195 handheld. I do use the Garmin when in the clouds, as a backup and for overall situational awareness. In my case, my VFR Garmin is not nearly as good as my panel mount King. Installation is the primary difference. There is also the issue of training and just what you are supposed to do when. The King manual has written procedures for flight in IMC/IFR environment, the VFR unit does not. |

Explain. If you require explanation, it would be useless. Jose -- He who laughs, lasts. for Email, make the obvious change in the address. |

IFR with a VFR GPS
Have you ever read either TSO-c146a or TSO-c129? One of the requirements
specifies that the database in an IFR-certified box adhere to a higher tolerance of corruptibility. Are you sure the VFR portable's database was built to the same specifications? If not--higher risk. I can go on and list each item-by-item but you seem to be literate so you can read the TSOs at your leisure. Bottom line is as I stated in my previous post that you don't personally believe the requirements outlined in these documents reduce risk in any way, shape, or form. If that's the case, I'm glad you don't help the FAA develop these standards. Marco Leon "Steven P. McNicoll" wrote in message k.net... "Ron Lee" wrote in message ...
