People pay more now for radios/nav setup than what an aircraft used to cost

A plane is also more expensive with a modern LSA being $300k plus.

Both the new plane and avionics are very capable.

I think you have to register for Van's Air Force these days.

Any more capable than a brand new Cessna 182 for 60K in 1980?

[Garfly]

I see that that the wee CubCrafters bush plane comes with colour TV these days  - and a turbine motor too, if you like.

I reckon you could land one of those here for not much more than a mill and a bit Pacific pesos.

Not sure what a new 182 is but a new 172 is over a million today.

It comes with two Garmin efises.

I guess we should talk about the actual new efises.

 

GDU116B - base model, 11.6 inch screen, fits same mounting hole as 10 inch G3X Touch, faster processor, sharper screen,

        lots of small feature updates, minor wiring changes, internal VFR GPS, $8-9K Aus $.

 

GDU116C - all the above plus, internal audio panel, internal com radio, internal IFR GPS, $26K ?

 

GDU116NC- all the above plus, internal audio panel, internal com/nav radio, internal IFR GPS, $33K ?

 

Needs current model ADAHRS, GEA25 (sensor interface) etc

Also works with the current model IFR navigators, ADSB transponder, AP controller, radios, standby instruments (G5, GI275)

Aviation 101 AXIS flight displays to Oshkosh

 

[skippydiesel]

I confess I love my iPad/OzRunways. Not only does it make planning/navigation a doddle, it increases my awareness of aircraft in my vicinity (combined with SE2).

 

I have a Dynon Skyview Classic ADAHRS & EMS. Took me for ever to transition from my old "steam gauges". Other than the weight saving (includes emptying wallet) I am not convinced that it has enhanced my flying experience one jot.

 

For Day VFR in small little aircraft, this "luddite" is of the opinion that the glass screen, has more to do with poser rights than practical benefit.😈

might be a colour tv but it only has a boring geography channel. no netflix

Great that I’ve found out that having aural AOA information, pictorial display of traffic both on the PFD and moving map, nav info such as TAS, OAT, ground speed and winds aloft, colour banded depiction of engine parameters with aural warnings of exceedances and the capability to record and download engine data, a capable autopilot, and a host of other features make me a poser.

 

I actually find that a lot of this stuff enables more attention to be focussed outside the cockpit.

 

I guess we should all be driving Morris Oxfords still.

 

I’d venture that holding of an opinion that those who like and find useful glass are posers says more about the maker of the statement than it does about those users and owners who happen to like such kit.

I've never driven a Morris Oxford. They did nothing for me. Autopilot's have their  Place but also their risks and downsides. You have to Know what the risks are. IF you like flying why do you need an autopilot? They are Not cheap A simple Plane can be flown safely with a bare Minimum of Instruments. You are a VFR pilot.  Have one gyro Instrument for Emergency A rate turn needle is enough if you are trained. An A/H is better. Nev

I am not against people having "all the bells & whistles" - good luck! to those that want it.

 

Yes my Dynon has an A of A - not so useful in my Sonex, may have a part to play for those wanting to play the  'Bush Pilot" & do a lot of STAL type of flying. I have landed my aircraft on two occasions without any airspeed indication - so much for needing (as apposed to wanting) an A of A. I was trained to land on the stall warning - if it was indicating at the "Flair" you were doing a pretty good job.

 

I point out, as a pilot who trained & flew GA aircarft in a diffrent (steam gage) time, most of this "stuff" is not necessary (a want not a need), does not contribute to safe more efficient Day VFR flight . Some of the GA aircraft, I flew, had "George" (autopilot) cant say I used it very often - perhaps that had to do with my longest flight, about 4 hrs (if I recall). It was just another nice but not necessary "thingy" in the plane.

 

I have  adopted iPad/OzRunways/GPS , coupled with a Skey Echo 2, as not only an enhancement to efficient planning & navigation but also a leap forward in safety awareness. I am not a believer in the capacity of human eyesight to "acquire"  other aircraft effectively. The radio and my trust Ozrunways/SE2 are my best pals, when it comes to alerting me where to look for that nearby/converging aircraft.

 

My Dynon Skyview Classic EMS /ADAHRS is kind of fun, expensive and does not improve my aircraft flying/management one jot, over the steam gauges in my last RAA class aircraft.

Being able to download engine history could be useful,(my Son liked playing with this feature) in the unlikly event that my trusty Rotax 912 ULS (no EMS) has a mystery symptom, beyond my diagnostic abilities, developed over the last 60 years or so. Future generations won't even bother to develop the engine management/diagnostic skills that us "old farts" absorbed as a mater of course.

 

So I pick & choose what I believe enhances my flying experience.

 

As a the owner of a Morris Minor (not an upmarket Oxford), ex postal van, back in the early 1970's, I would be happy to own & drive one today. 45 miles /gallon (about 5L/100km) no matter how hard I drove it - 4 speed gearbox, as smooth as silk - tuned to perfection she topped out (peddle through the floor) at 80 mph (129 kph)- didn't corner so well, as van springs allowed her to "lift a leg" (wheel) if you went too hard. (a safety feature?).

 

FYI : Your examples TAS & Ground Speed are available on my trusty old Garmin GPS handheld( & on my iPad) - still have as a back up. OAT has always been available as a stand alone steam gauge ,as has RPM, EGT, CHT, MAP, Alt, Climb,  AH (if you wanted, )etc, etc. The big benefit in the EFB systems are weight saving, not pilot information.

No trusty old Garmin GPS handhelds ever gave you TAS. How could they, without access to IAS, OAT or Pressure Alt? 

 

In any case, even as you wish good luck to those who seek bigger, better 'glass-screens' than yours, you still suggest they're more into 'poser rights than practical benefit'.

 

But then, you've always enjoyed a good debate for debate's sake.     ;- )

One thing I found odd with the new "one box" garmin Axis is how much custom wiring is required to connect it to the other garmin box's,  transponder, audio panel and auto pilot.

Does Garmin offer prefabricated D-sub harnesses of different lengths to hook up everything that’s on the can bus?

 

I recently observed the professional installation of a whole G3X installation and was surprised to see the techs individually constructing these.  On my recent Dynon HDX installation I found it a great help to simply buy those harnesses pre-made; they come in a large range of lengths.  Only the long ones where you couldn’t thread the “plug” didn’t come with D-dubs on each end.

 

But as you say, still a heap of wiring outside the can bus…..

Ill give you the TAS on my trusty Garmin  - but not hard to estimate TAS based on altitude and indicated airspeed - just add 2% to indicated, for every 1000 ft..

 

Anyhow, the core of my argument is simply that, asides from significant weight reduction, the glass screen does little if anything to add to the pilots safe/efficient operation of the Day/VFR aircraft. When purchase cost and reliability (repair/ update cost) are added, the screen becomes even more suspect. 

 

The glass screen is the way of the future - not apposing, just pointing out its allure is far greater than what it actually delivers (much like all the extraneous crap fitted to cars these days).
