I read cockpit GPS and found it very informative. My budget for a new/used GPS was max $250 Canadian (tax not incl). Based on the info I read, I purchased a Garmin 72. I used it for a while but returned it as I did not like it for the type of flying that I do. I purchased the Magellan Meridian for under $200.00 I have had it for 2 weeks and I like it. It is easy to use, solidly built, it has a very basic map with airports on it, it has twice the memory of the Gamin 72, it accepts additional memory, it does everything that I want it to do and it fits my budget. I would not hesitate to recommend it as a cost effective supplemental navigation device for the "week-end pilot". K. Kiltz

Your site was a fantastic and timely find! I'm teaching a new course at our high school this fall - Managing Outdoor Skills, Science and Technology and your site is the best source of information on USING GPS that i've ever come across. Thank you for the effort you put into this. I hope I can find an "internet connected print shop" in our area to get a good copy of your book. RE: your question about teaching gr 4 kids about lat/long - how about seating a kid in a chair that can spin, in the middle of the room and give them a pointer stick. They pretend they are at the centre of the earth and "someone is stomping on the ground up there!"(pick a point on the wall or ceiling) Have them point up (lat) and spin around (long), (from some starting point - prime meridian) to zap 'em. cheers ps...Alternative idea - YOU sit in the chair, blindfolded. Kids post "targets" around the room and tell you how to aim by giving lat/long of target. fpianka@hotmail.com www.norlink.net/~alpinecc/

I often notice, that especially private pilots do not know enough about the problems with handheld gps receivers and that many of them do just believe that they are save as long as they have this units. I always do a manual flight planning (Route, W&B, Fuel) and use a handheld gps as an additional help, no more. Also, to power the gps from a cigarette lighter connector is not a very safe way (from a technical standpoint). In addition, many of the handheld units are far too complicated for use in a small aircraft with a single pilot (he has to fly the aircraft, look around for other aircrafts, communicate with FIS or radar controllers etc. etc.). A better/ another way is, to do the flight planning on a PC (for example: using Jeppesen Flight Star and download the entire route into the GPS)

John, this is the finest compiled information on the use of GPS I have ever seen. Very nice work.

I have finished my own short section on using the GPS for soaring navigation and am interested to learn more from a broader perspective.

I was looking for a website to help explain GPS and the differences in aviation and non-aviation GPS units.

I really like the Garmin series, and based on your book - it sounds like a good choice. Thank you.

Thank You very much for this excellent book. Actually I was just in desperate need for such a detailed tutorial that would explain basic old-skool navigation (bearing, turn, xte, etc.) togehter with gps from a professional point of view. I always knew there are much more efficient ways of using gps but my personal lack of knowledge prevented me from doing so. This book helped me a lot. I always use gps paired with a good map while geocaching and hiking, sometimes driving. Who knows - some day I might be boating so this book is the best for homework. Thanks a lot!

Just a heads up to those in Canada that might be considering this unit. The mapping detail of Canada is pathetic to say the least. Therefore you must upgrade the base map when it becomes available. The shop where I bought mine never told me that theirs was specially set up from Lowrance for demo purposes and that the one I purchased would require additional upgrading.

I just downloaded the article and have not yet read it. Upon completion of the book I will give you my comments via email. Thanks again for sharing your valuable knowledge. Warmest regards/Chew

GPSMAP 296, Rino 110 and 120, have owned the GPSMAP 196, GPS III and GPS V, and an etrex. All Garmin

Dear John, Thanks for the Cockpit GPS Guide. Although I have a pretty good background with GPS equipment, it's always nice to read another pilots ideas, and as always, I've learned something new. --------- Garmin's GPSMAP 296 --------- I thought you might want to hear about my experience with Garmin's GPSmap 296, so here's some details. I purchased the new GPSMAP 296 at Sun 'n Fun and flew with it back to Indiana, about 700 miles in a C182. The unit really works as well as Garmin suggests. If you own a GPSMAP 196, you'll be at home with the 296. The lithium rechargable batteries works great and lasts as long as advertised, even with the backlight on. The terrain warning and obsticle warnings are also great and work as expected. The display was bright, sunlight readable, and the mapping detail is excellent; airspace, MOA's, restricted area's, and all Navaids show up extremely well. The display is more like a sectional than a typical GPS and the colors make things much easier to pick out. The processor is also fast and panning in map mode works just like the 196 even though it's moving colors. The software is improved over the 196 with some added feature, and with some OS upgrades it'll be even better. Don't get me wrong, the unit operates flawlessly, but Garmin always strives to update their software. One thing I hope Garmin offers for the 296 in the near future is a headset/intercom interface. It would be great to hear the terrain/obstical warnings in your headset. Since the 296 outputs sound in driving mode, I would think this feature would be easy for Garmin to add. Thanks again for all your efforts. Sincerely, Richard

Garmin GPS 12 Hard going but quite a lot of features if you can use them

FOR SIMPLE GPS (GPS 12) When boating and sailing in waterd full of stones it might be very necessary to keep as near to the routeline as possible. TURN right takes you in a stright line to the next waypoint, that is true but there might be something nasty like stones or low water on the stright route. The amount of the TURN reading that tells you that you are dangerously off road depends on the obstacles etc. When tacking you can in advance figure out danger readings on both sides of the track In such situations I should recommend to take a course 90 degrees off the course and return to the right path. The highway can best tell you when you can turn to the next waypoint. I had such a problem in a dense fog two years ago and had to stay were I was until the fog disappeared. Using the GPS in this way might well have helped.

built-in, will probably buy airmap 1000

I just discovered your site, and have not yet fully read even the one document that I stumbled on---but it seems terrific. obviously a labor of love. so, I just wanted to thank you. I will read it very carefully. I just sold my RV-9 (GNS-430), and will be purchasing an RV-10 (CNX-80). because I will have to rent until then, I think I will purchase an airmap 1000. I have to admit I am one of those pilots who trust GPS's with good maps and terrain avoidance so much that I would not fly without one. in fact, I strongly feel that they should be mandatory as gyro backups---I can easily hold the plane level AND maneuver to an airport if the gyro's go out in IFR; I could not do so without. chances are that everything else in my airplane will die before my handheld GPS will die, especially if it has a hookup for electric input and battery input. IMHO, an ok pilot like myself *with* a working handheld GPS can survive total avionics failure. examples of dead pilots with (creeping) vaccuum failures abound, of course. now I need to go back to what got me to your site---looking for whether I can find good mounts to place the airmap 1000 into my VW Passat and one a control stick (not yoke). regards, /iaw

Minor nit about your document: to legally fly an approach using GPS as primary navigation, it *must* say "GPS" in the title, even for RNAV approaches. I just discussed this with an FAA examiner who concurred. It came up because there are some VOR/DME RNAV approaches at KFNL that can't be flown with GPS and require older RNAV equipment. The Garmin 430 database will have a small "gps" next to legal approaches and this one didn't have it (which was surprising, and prompted my question to the FAA). This is stupid, but in the same category as an "NDB 33" approach before it became "NBD or GPS 33".

Done

You have a great site and show great empathy for those who need to learn. I am retired and 69 years of age and have always been interested in GA. My father used to take me on weekends in 1940, or so, to the grass strips near my house to watch the Stinson's and Cubs practice. Of course the grass strips were all shut down in 1942 so we limited ourselves to the Youngstown, Ohio commercial airport with their DC3s coming and going. If I can pass the physical I will get my license and hopefully build a Van-7A soon. I can't tell you how much I appreciate your site and the small token I have sent does not reflect your site's true value.

The instruction booklet that came with the unit is almost useless. I can't thank you enough for de-mystifying it for me. I have used it on several cross country's and am still amazed at how it makes navigating so simple, compared to how I used to use the VOR's and pilotage. Again, thank you.
