Hi everyone I am at that point in the build where I need to start thinking about things like NAV/COMs and GPS I have been seeing alot of Garmin GPS 100 and 150 for sale reasonably cheap however I dont know anything about these units and dont want to buy something that cannot be updated with current programming. Any advise on this would be helpful

Lenny, I can't speak to the specifics of those models but maybe if you let folks know what you're flying, what kind of flying you do and how much you are willing to spend you might get some suggestions. Cheers, Matthew

I recommend the Garmin 250XL GPS/Com. Fairly inexpensive used. Has moving map and flip/flop com. If you're looking for a portable instead, I have a Garmin 496 that I'm going to sell and buy a Garmin Aera. I was amazed how easy the Aera is to use.

If you're interested in a portable and having a large screen the Lowrance Airmaps are good options.
They are no longer in production but you can buy updates for the 500, 600C, 1000, 2000C. eBay and Barnstormers usually have a few used ones for sale for a few hundred dollars.
The 2000C has a big 7" color display and is really liked by those of us who own them. It doesn't have a touchscreen or XM weather if those are important to you.
I did temporarily switch to an Anywhere Map Quadra and quickly went back to the 2000C. The Quadra had a smaller screen and too many software bugs associated with its innovative features.
Personally I've stayed away from panel mounts due to installation complexity and lack of flexibility if I ever want to upgrade to a different GPS.

No specific recommendation beyond making sure it can be updated as part of the package and has civilian fields programmed in, including all on-ground features. I would recommend "Shorty's" as the place to at least window shop before making the plunge. ...and then remember, you still have to know how to fully navigate without the blasted thing. I was on the 1st ARINC committee that established GPS use for civilians and also the Military committees that developed GPS and the algorithms for the navigation systems; as a Geodesic Engineer I wrote a lot of the WGS 1984 and updates into the systems. Don't forget that in wartime, you will want to use that aircraft - and those GPS satellites are terrific and easy targets out there and will probably be the first to go in a big one. You might still want to know how to get from point A to point B. I would go as far as say it doesn't hurt to know how to take a rough star shot just to know which way you are going, at least be able to look at the sun in the morning and evening at a given latitude and know your true heading. I have flown across the pond on DR and hit small islands using a bombsight to get wind direction and speed off the waves and weather reports to know what it should be at altitude. You then also have the charts for sea level and adjust for actual conditions when visibility allows. A straight tube out a window plumb to the vertical can accomplish the same thing if you are low enough to see the waves and are familiar with how to read the wind speeds. I recommend along with a good IFR course you also read and KNOW Dutton's or Bowditch's Navigator, old books for Seaman, but navigation is navigation and dead reckoning is dead reckoning.. Last point - NO pilot should stop his training at VFR only, - too easy to become IFR qualified. Put off getting that plane for just a little bit and learn how to fly it, I've seen guys do good basic "save your butt" IFR with a styrofoam cup 2/3 full of water, and a 8 inch string taped at the bottom to the windscreen and a small weight tied to a 12' string suspended from the ceiling of the cockpit. We used that cup of water for several things including syncing our props, the water spins towards the prop that is going slower so you add a little rpm until you get concentric circles. Little splashes in the center were backfires or misses we couldn't hear, they went towards the affected engine. The string on the window, that was our slip gauge; If it got a sine wave in it - very early indication of a high speed stall. The weight on the string never lied and never needed to be reset, always told you which way was up. - Best wishes, NIGHTSTALKER

I apreciate all the information I already have a full six pack and Im no stranger to VFR flight and dead reckoning I am also planning on getting my IFR not that my intentions are to fly in IFR conditions but one never knows what they could end up in.. I am excited to finish my plane and get it flying but im just looking ahead to make sure I have everything i need installed I am not starting to think im going to go with a non panel mount gps which I think will be easier in the long run.. I am also looking at putting in a Dynon small flat panel I believe its a D60 and I have heard alot og good things about them.. Again thanks for all the god info

I haven't really posted a lot about my plane I'm kinda new to all this.. My intentions are to fly as often as possible and not just hang around the airport.. I haven't done a lot of flying since I started my plane because I would rather put the money in it than in renting someone's plane.. I fly enough to keep my skills up and stay current.... OK to ans the big question I am building an all composite two place airplane with a T tail and canopy it has fixed seats and adjustable rudders and is stick control if I had to describe it I would say it looks like a Diamond DA20 or a Piper Tomahawk. I was originally going to put a subaru engine in it but now I am looking for a Continental o-200A which will be a lot less hassle and more reliable...

How much are you going to ask for the 496 ? Also is it portable or is it hard wired to Aircraft ?

A lot of us now are so dependent on all the whiz-bang avionics, that 'dead reckoning' often gets blank stares, then eventually - 'oh, that!'
That quick primer on 'save your butt IFR' was simply amazing. I truly believe that they should make it a part of the standard syllabus. I wouldn't be surprised if it saves more than a few lives.
I'm waiting to try it out!
Thanks a ton

Lenny, when I got my IFR rating I redid the panel in my plane. I decided to go with a King 89b and I also panel mounted a garmin 496. The king gives me certified en route and certified non-precision gps/rnav approaches and the garmin gives me weather. I've been in and out of some fairly nasty stuff and I don't regret what I installed one bit. I bought the king yellow tagged for about $1200 and bought the 496 new. Good value for the safety they both added!

William, IMPRESSIVE! when i got my IFR rating the pucker factor really was high during the "no gyro localizer" approach. The cup of water and string takes it to a whole new level
