Outside the U.S. you better fly IFR or have a current topo aero chart. |

Who flies that low? I do. All the time. I like to fly at 500 feet, but the towers are getting a bit too numerous for this around here. Jose -- You can choose whom to befriend, but you cannot choose whom to love. for Email, make the obvious change in the address. |

AGL was being extravagant with fuel. |

Ok, I give up. Would someone post the URL where I can download the
terrain update for *free*. (I can only find the Garmin page where you have to pay the $295.) Is Garmin really giving it away for free? Or did you find an unsupported back door? Thanks in advance!

Garmin just updated the terrain 2004 data files to 2005 and, for a time (probably a very short time) all three coverage areas can be downloaded FREE from the Garmin site. |

Go to aviation database tab, then select your unit (296 or 396) then select "terrain" and it will say: "Single Update: Regularly $295, but for cycle 05T1, the database is FREE!" Nothing tricky or back-doorish about that. ;-) |

This brings up an interesting idea of putting an electronic beacon on new structures for the first year or so until all terrain data bases get updated. That's basically an idea we submitted to the FAA many years ago, back before ADS-B was called ADS-B. In addition to the usual "squirt/listen" in each aircraft, add a simple squirter to each tower above a certain AGL height (same as the "flashing red light" rules). Nothing special required to the aircraft installation - the antennas and other such obstacles simply look like aircraft to avoid. Total cost (we were talking about low power VHS) of the transmitter in todays dollars would be around $15 per tower (less any FAA administration fees and liability insurance). Even that is probably a high figure - more for the weatherized case than anything else. Since the obstacles presumably never moves, no GPS required - just a fixed string msg. [Oh yeah, the then administrator nixed the idea. Said in-cockpit weather and aircraft imagery was too complicated for pilots to understand, and that the only thing he would EVER approve was the uplink of text weather and charts.] |
