Dumb GPS Question
I've just bought a TomTom GPS for my car with preloaded road maps of the US
and Canada. My question: Will it work in my 172 at 3,000 to 5,000 feet, showing the roads below, etc? |

William,
Will it work in my 172 at 3,000 to 5,000 feet, showing the roads below, etc? Sure. Following the turn-by-turn instructions will be rather inefficient flying, however. Might be a great way to build time, though ;-) -- Thomas Borchert (EDDH) |

There was a time when Garmin GPSes meant for terrestrial use would cut out at around 100mph, which limited their usefulness for aviation. But that was a long time ago. It's doubtful that TomTom did that same stupid thing. There is an on-line book at http://www.cockpitgps.com/ that has some information about using non-aviation GPS in aviation. -- Paul Tomblin http://blog.xcski.com/ I wouldn't be surprised if I'd have to put garlic in the CD drawer to really get rid of it. -- Arthur van der Harg on 'Gator' |

It will, but a better way to use it is to zoom out to show your position in relation to towns, cities and geographic features - in other words, Situational Awareness. A terrestrial GPS is a good backup, but one with an aviation database is vastly more useful for flying (IMHO). David Johnson |

Might be a great way to build time, though There's a route through the EWR class B called the "GSP Transition". It's not an exclusion zone; one gets clearance through from the EWR tower. But it's a well-known path for both pilots and controllers, following the parkway below. I've been told that this was originally for traffic observation, but I don't know that that's true. I was flying this with a CFI once when he pointed out that one doesn't have to follow the road as precisely as I was. But that's the fun! - Andrew |

I have seen over 700 kts on my Garmin . . . once in a United 737, it must have been a mother of a tailwind. This is back several years ago when some airlines were ok with GPS in the cabin. Take care . . . John |

I have tried Tomtom (on Dell AXIM) on an airplane and it doesn't work. It will get a fix of your position, and you can watch yourself fly across roads, lakes and rivers. But you can't ask it to navigate anywhere. In order to compute a route, you have to stand still for a while (for long routes this could take a couple of minutes). In the very least you should stay on one road while it is computing. Since you are obviously not doing any of this while flying, the program will never finish computing the route. My screen just said "computing route" with a progress bar for a very long time. When it seemed like it was getting close to the end, it would start all over again, and the cycle never stopped. My guess is by the time it computed a route, we were far from that position and an entirely new route had to be computed. This may also have something to do with the processing speed of the Dell AXIM. However, even if you ran this on a faster platform, it might still be constantly recomputing a new route because you are obviously not following any of its suggested routes. One possibility is to fly over a highway in a sparse area, and it may be fooled into thinking that you are actually on that road. But that might also be hard to do because it is quite sensitive to your position. If it thinks you are off the road, it is going to start recomputing again. It was fun trying it, but I can't see how this can be made to work. If you really need to find a street while flying, the best approach is to insert the lat/lon co-ordinates into a regular GPS. |
