I don't know what your practice will consist of, but wouldn't the free 

Garmin trainer serve that purpose better? See this for (very large) down 

load:



https://buy.garmin.com/shop/store/downloadsUpdates.jsp?product=010-00412-01&cID=194&pID=301



I have this trainer on my computer and it works great -- probably better 

than anything that you could set up.

I want to build a power cable so I can practice using my Garmin GNC 420W at

 home. -I called Garmin and was told that I can order their $125 connecto

r kit to build my cable.



The GPS side uses a 78-pin connector that looks like a D-subminiature 78-pi

n connector. -Mouser has them for around $10. -But Garmin tech told me

that their connectors are not "computer connector" but "aviation connector"

; at $125, it sure feel like aviation grade and

price.



Would this work: http://www.mouser.com/Search/ProductDetail.aspx?qs=EP%2f

Good Morning OC,

  

 I tend to agree with your suggestion and I do the same thing. 

  

 One fly in the ointment does irk me somewhat. Garmin has not updated the  database in the trainer for almost eighteen months. In the past, they have  updated it almost every year. I like to go through approaches at home before I  execute them for real. 

  

 I have considered getting a docking station for my 430W just so I could  practice while using a current database.

  

 I do that with the GNC 300XL that I have in my Stearman. I wish Garmin had  been as kind to us with the 430W as they were with the GNC 300XL!

  

 If anyone cares to enlighten we electronic amateurs as to how to wire a 4  or 500 series Garmin box for simulated use. I would sure appreciate having that  information.

  

 Happy  Skies

I'm curious... what is available for the 300XL to enable practice at home?



I have a 300XL in my Maule.  I got the instrument ticket with it and 

flew it IFR quite a bit but  using it well is always a challenge if not 

more than current.

Good Evening Bill,

  

 All it takes is power. There is one of those little quarter inch or so  plugs just for that purpose. I use a universal Radio Shack 12 volt DC power  source.  

  

 There is a simulator mode. It tells all about it in the operators manual. I  just sit it on my desk, plug in the power cord and shoot approaches as much as I  want. It isn't as nice as a good computer program, but it does allow me to  practice the steps needed for an approach. Since my Stearman is not legal for  IFR, it is just a toy, but If I ever got stuck, I just might use it to find a  place to land!

  

 I have shot a few approaches under the hood with a safety pilot in the  front pit. Actually works quite well. However, as you say, if you don't use it  much, it is easy to forget the required steps.

  

 Happy  Skies

Thanks Bob.  I forgot about that feature once the box was in the plane. 



Given the critical role of the external annunciator panel and the 

interaction with my single CDI head, the things I always need to review 

require the whole panel.



It's a nice box for it's time.  The thing it really does easily and well 

is a full GPS non-precision approach - the T shaped kind.  No vectors.  

Short of vectors to an ILS, it's about the simplest thing to do with my 

setup if the brain starts to tumble.



Did you ever think you'd be able to call a GPS panel in a Stearman 

'ancient'?  As in,

"wow, this thing doesn't even have synthetic vision...."

"it doesn't have windows either, just stick your head out!"

Good Afternoon Bill,

  

 I did wire up a series of lights and switches so that I am able to use all  GPS Approach functions in the Stearman even though I do not have a classic CDI  or annunciator panel. Consequently, just playing with it at my work table does  allow me to practice my approaches.  

  

 I think Garmin dropped the ball when they acquiesced to one stupid FED who  insisted that Garmin add the resolver and the annunciator. Fortunately for all  of us, that FED was replaced with a more sensible inspector, but the damage was  already done and we are still stuck with a deal we don't need. Such is  life!

  

 Happy  Skies

No annunciator  is needed if the 430 is mounted within 14 inches of the centerline of the six pack  (that number is from memory but it’s spelled out in the install manual).

Good Evening Tim,

  

 If the 400 or 500 series box is located in the pilot's primary viewing  area, no annunciator is required. Not sure whether or not that applies to  homebuilt aircraft. For a certificated aircraft, the dimensions are quite  specific and are based on the pilot's eye location.  I am absolutely  certain that if a homebuilt location meets the certificated specifications, no  annunciator is needed.

  

 Not sure about the various EFIS units, but I wouldn't be at all surprised  if they did.

  

 Does that help any?

Good Evening Once Again Tim,

  

 My primary gripe with the stupid FED was his insistence on having a  resolver function for the standalone GPS units. For a combo GPS/VOR like the 400  or 500 series, the resolver is a non issue. It is needed for the VOR portion.  For the other early GPS only sets, we could have a thousand bucks per  installation had the resolver not been required. Not only that, the set would  have been easier to use, but that is all water over the dam now!

Hello Robin, Please tell me more about this demo mode. How does one get into 

it and use it? I can't find out anything about it in my 430W manual.



If you have the Garmin trainer on your computer how does the demo mode 

compare to the trainer?



Thanks.

 I too would appreciate knowing how to use the 430W in demo mode!

  

 Incidentally, I did not receive Robin's message concerning the pins to be  used. Fortunately, you (OC) copied the pertinent data in your message.

  

 Thanks a bunch.

Demo mode on the 430W is achieved by grounding pin 75 on connector P4001.  From the install manual page 4-10: 

4.5.1.12 Demo Mode Select

This discrete input may be used to select Demo Mode on the 400W series unit.  A low on this pin at time of unit power-up invokes the demo mode.  Demo mode allows the 400W series unit to simulate reception of GPS satellite signals.

Caution: Do not connect DEMO MODE SELECT in an aircraft installation

The built in demo mode simply simulates receiving GPS signals.  You can load a flight plan, select approaches, etc.  Primary benefit of using the actual unit is that you get used to the "buttonology" of the box.  The computer version that can downloaded from Garmin has the additional feature of a throttle control but you're using the computer mouse/keyboard to drive things.  Both have their pros and cons.

Good Morning Bob,

  

 I did see that in the Installation manual, but I have not found any  guidance in the Pilot's Guide or the installation manual as to how to use the  Demo Mode. 

  

 Is there a method to input speeds and such as we can do in the GNC  300XL?

I recall seeing a speed input in the setup menu someplace, but that's quite a bit different from having a throttle control like you've got with the PC simulator.

When you've got demo mode selected the 430W comes up and shows that it's receiving data from all satellites (kind of a spiral pattern on the satellite view screen).  At that point you treat it just like it was in your plane - enter a flight plan, select an approach, etc.  There's a way to select present position but I don't remember how off the top of my head.  Once the flight plan is entered the unit makes turns as necessary to track it and you can watch the screen update, make changes, select approaches, etc. just like you are in the plane.



BTW, if you've seen the Commander units for panel mount GPSs, all they are is a power supply and cable that plugs into the back of the GPS.  On the 430/530 series they ground the demo mode pin in addition to supplying power.
