Crazy Thoughts...

[N1026F]

I'm thinking of selling my 530W and 430W to buy a 750 and a non-display standby NavCom with 3d audio. The truth is: the redundancy of dual displays is really overkill; I use the 430 for 2ndary monitoring (like most) and the demand for the 430W and 530W seems to indicate its a good time to sell. Line up folks--how crazy am I?

[Rwsavory]

I would consider doing the same if I were you.  With Ipads and other portable moving maps available, there's no need for a second panel-mounted GPS these days.

Back in the day...

Nav/coms broke or wore or did unexpected things...

To maintain any type of schedule, a dependable (certified) back-up would be required.

Voice and VOR were typical of the back-up. Voice and ILS were primary.

Today...

It may be good to have a back up nav com to get you out of a bad situation. You may need to go to an airport with ILS if the GPS and graphical presentation died...

But having two graphical GPSs sounds like over-kill if they were required. Nice to have, but not required.

In the 90s, my plane was built with a pair of nav/coms, one has the ILS. A basic IFR GPS has been added along the way. The only significant graphics I have are on my IPAD.

So if you need to split the money two ways. Spend more on the GTN7XX or avidyne or BK top of the line and minimize the investment on the second radio. My #2 only gets used because my memory is limited, and I fill four memory slots with frequencies for the airport.

I'm looking forward to seeing what B-K has with the new box coming out...

How does that sound???

I have a GTN 650 which crossfeeds to my panel mounted 696. The 696 affords me a cheap xm weather option and a battery backed up GPS in the event I lose ships power. The 696, as with all of garmins portables, displays extended runway centerlines which I like as well. That's something my 650 doesn't do...and if it does do it I don't know how to make it do it. My other back up is the iPad running foreflight. Along with my venerable kx-155 I think that's the best/cheapest redundancy out there right now.

What is the value of the 3D audio?

Is anyone making use of it currently?

3d audio; neat new gizmos... the upgrade could possibly leave enough extra $ to do the ADSB upgrade...still doing my homework... the math is still not clear yet.

The 3D audio (Garmin) works very well I can hear both radios clearly with understanding. Great for monitoring ATIS while talking to ATC, or while keeping tabs on the "old" frequency when switching to the new frequency as assigned - just in case you used the wrong new frequency. Also works well with the air to air frequency and monitoring local ATC or airport frequencies. It's more than just porting the two frequencies to opposite ears, or at least it seems that way to me. Having both a GRN 750 and a GTN 650 (with the GDL 88 ADS-B in/out),I have found that for me the best use of the GTN 650 is to decouple flight plans from the GTN 750, set up a separate VOR to VOR flight plan, but use the display for traffic - "relative" at the 6 mile range. The GTN 750 will show traffic at greater ranges on the moving map, but the detail (dangerous situations) are tracked on the GTN 650, and then the 6 mile range can be reduced to 2 miles. For "participating" aircraft, you can pull up a data block that is close to what ATC sees. Now that I have had my "new" panel setup for close to a year, I wouldn't change a thing. Overkill in some respects, and expensive, but I like the redundancy, but even more importantly, the incredible functionality.

I have the Garmin 3D(350 i think) audio panel and like it for the same reasons as Bennett. IIRC it was a small price difference in aviation terms. It also has a push to control (PTC) button that I don't use but it came with it and I have a feeling some day it will be integrated for flight plan entry, maybe. I'm sure when that happens that Garmin will have a $10K control cable I will have to buy to make it work.

I also use the large display for my flight plan and the small screen for TIS traffic in congested areas or terrain in mountainous areas. But I know your dilemma because I actually defer to my WingX pro while I'm in flight because it is so easy to use and flip flop or split screens and get more information than you can process.

Oh, I forgot to mention that I already have the G500 with synthetic vision. Bennet, thanks for the description of the 3d audio...

Runway extensions on the 750/650: From the Map page tap Menu, tap Map Setup, tap Aviation, tap Runway Extensions, tap the length you want.

Don is correct on the setup, however, the 750/650 doesn't display all airport centerlines. FA40 is an example of one it does not. The workaround is simple. With the airport as the waypoint, put the GXXX, 4XX, 6XX, 7XX in OBS mode, and dial the obs nob to the runway heading. You will have a Magenta line now for runway extensions. This is also the method to use when instructed by ATC for a non published hold.  "Hold southwest at Podunk on the 240 radial, Right hand turns".

Makes it much easier

If I'm not mistaken the 650 and 750 both have a 'monitor' function.

 

On the 650 touch the standby window to call up the freq pad.

If not already set, select your standby freq.

Touch the 'MON' button to turn on the green light.

Go back to your normal display.

 

You set the primary up, then in the standby window you set the frequency you want to monitor and select 'monitor'.  You are then listening to the standby freq.  If something comes across the primary it cuts out the standby freq and you then hear the primary instead.  Personally, I can't listen to two conversations at once anyway.

Not a crazy thought at all.  I have a 530W/430W (both came with the plane, but I did the W upgrade x2) and after flying behind them for years I'm not sure I would put in two GPS/com boxes if starting from scratch, and especially if budget is a concern.  I have no experience with the 750, but with the big screen surely you can show enough of the data fields to cover the bases.  My 430W stays on Nav 1 page (6 data fields) nearly 100% of the time to supplement the 4 data fields on my 530W Nav 1 arc view screen.  Supplementing and backing up any panel-mount with a 496, 696, tablet, etc. is certainly helpful as well.

The truth is: the redundancy of dual displays is really overkill; I use the 430 for 2ndary monitoring (like most) and the demand for the 430W and 530W seems to indicate its a good time to sell. Line up folks--how crazy am I?

Keep in mind that right now you have dual GPS, and dual LPV capability that you would not have with a single GTN 750. Is the trade off going to change the mission profile? It will degrade your GPS navigation/LPV capability to a single navigator.redundancy.

 

Here is an interesting scenario. On your destination to KXXX it only has LPV approaches and you are in solid IMC. If your GTN 750 fails you have to switch to another airport. But on your current configuration if your GNS 530 fails you can still do the LPV with your 430 and land at your original destination.  

 

The GTN-750 has some real nice features but for me is not worth the trade off and installation hassle. I can access the approach procedures on the 530 by just pressing a single key while on 750 you have to go through multiple screen key entries. On the 530 to view the different pages is just a matter of rotating the right knob just a few clicks.

In the process of buying an old Mooney. A 430w would be a perfect addition to my only VFR panel. How much are you thinking?

[carusoam]

Learn the search function and you will find many of the things you are interested in.

A 430w is a nice addition to any panel, so their price for the hardware is around $6k + installation.

Look to eBay for actual examples of 430Ws that are for sale.

Hope that helps...

Amen to that.... There seems to be a proliferation recently of folks, mostly new-bees who throw questions out to us seemingly without even a cursory search or description of what they've already discovered. Wonderful MS folks, many times accommodate these recurring questions, but may be also be encouraging this IMO boorish internet behavior. Now I feel better

[carusoam]

Gary,

I must have my sales guy hat on today. I'm being unusually nice, and pontificating benevolence...

One of these guys (M20 B/C/E) will be moving up to a long body just about the time when I'm moving down to my retirement M20E.

Hopefully, I have made a friend today...

On the other hand, it is the Internet. He probably missed my intention and will quickly throw a barb in my general direction.

Welcome aboard Wakeup,

-a-

[Rwsavory]

Wakeup was probably asking OP what he would ask for his 430. You guys are getting cranky in your old age.

[Wakeup]

Thanks for all the responses. No hard feelings. I don't even have the plane yet and I'm already looking for upgrades. I'm just excited that I may have my own plane next week if everything checks out. It's only set up only VFR so I would be happy with any new upgrades.

[donkaye]

There may be a good reason to keep the second GPS if you have a G500 or are thinking of getting one.  Should one of the GPS units fail, the other unit would keep the G500 going.  Regarding the use of the GTN 750 vs the GNS 530 to pull up procedures; at most there are 2 button pushes, and they can be done so rapidly that I'll bet I can get an approach set up as quickly as on the 530.  In other regards it is so much more superior that it would be hard to know where to start with the extra benefits.  For one though, the topo map is soooo much better for situational awareness.
