Sales and Marketing folks are finalizing their program that will be available for anyone interested in upgrading their IFD540 to an IFD550.

I've seen the draft and it looks pretty good.

They expect to publish those plans some time in the week of 23 May.

Steve,

What can we expect as far as installation requirements for swapping a 540 with a 550?

I assume it's a plug-n-play for the box itself, but are there external sensors that need to be installed?

Here are the details for the 550 upgrade program which we will be rolling out this week:

For current IFD540 owners
Avidyne’s IFD540-->IFD550 Trade-In Program is a limited-time offer for current IFD540 owners who would like to move up to the IFD550.  Customers can sign up now to trade in your IFD540 + $5,000 and get an IFD550 w/new 2 year warranty (or a full 4 years of warranty with AeroPlan®). This $5,000 upgrade pricing is only available until the IFD550 is certified. Upon certification of the IFD550, the standard 540-to-550 trade-in price will be starting at $7,000. Pricing does not include shipping or installation fees. Avidyne is accepting full-payment reservations for up to 10 upgrade slots per month on a first-come, first-served basis.

IFD550 Early Purchase
Avidyne’s IFD550 early-purchase program allows aircraft owners who do not currently have an IFD to act now and install an IFD540 today and swap it out for the IFD550 once it is certified—there’s no reason to wait!  Customer pays for IFD540 + $3,500 (50% of retail cost to upgrade to 550) now.  The difference in retail price between the IFD540 and IFD550 is $5,000. With this offer, customers can place an order for the IFD550 now, install a IFD540 today and only pay additional $3,500 (a savings of $1,500) versus waiting until IFD550 is available. Upgrade payment of $3,500 due at the time of initial purchase. With this program, the customer can begin to enjoy the ease of use and fun of flying the IFD540 now, and get the added benefits of the IFD550 once it becomes available.

For more information contact sales at 800-284-3963 or sales(at)avidyne.com

I know this is a foolish question to ask . .  but here goes . . . any rough idea of when the IFD550 will be certified?

Hi guys, A few questions from me: Is there any further wiring to be done to the existing IFD540 tray installation to make the IFD550 work? Will the IFD550 require factory installed hardware modifications after I install it? I assume the upgrade will be like for like... If I have the 16W Comms in my IFD540 then I'll have the same in the 550 right? I'm located in Australia, will you guys consider sending the IFD550 to my avionics shop before I send back my IFD540 to minimise downtime. And do you expect the FAA STC to be completed in weeks, months or years? I'd like to know how long I have to pledge my donation for an upgrade.
Cheers
Andy

This is not a complete certification but just an STC on the Attitude Reference System? Presumably a few weeks to a few months?

Aside of being a fancy display, what is the STC going to bring? Like, can it be used as a standby A.I. for a glass panel?

The upgrade from a 540 to a 550 can be 100% plug and play.  

There are asterisks associated with that statement.  For example, did you have heading input to the 540?  If yes, then you will get the TVV part of the 550 to show up. If not, then either you don't get the TVV, or you must add a heading source input to the 540.

But, there technically is no need to add any more wiring.   The 550 will not require any additional hardware mods that exist at this time.  If you have a 16W 540, then you would get a 16W 550 if you took advantage of the upgrade program that Simpson published.

I won't comment on the logistics of shipping boxes all around the world.  It will be so situationally dependent on the individual install - you will need to coordinate with your Avi Sales rep and/or your shop.

As for how long do we need to keep your pledge money - I won't answer it.   Every time I've tried in the past, things have gummed up those estimates and we felt the furor of customers who did not enjoy that uncertainty or unrealized expectations.  So for now, "it will be done when it's done."

For at least the initial cert, the IFD550 will be a "supplemental, non-required" additional source of attitude.  That means, whatever attitude indicators your airplane currently requires is unchanged.  You can not use the IFD550 to serve as one of your required attitude sources.

Architecturally, nothing automatically prevents the device from being used as a standby or even primary but that is not the cert we are seeking at this time.

I just want to slide the 540 out and slide the 550 to get SV.

Thanks for the info, guys!  

What is TVV? 

So, Will 10.2 be available before the IFD-550?  I would like to see how the in trial works in my 540s with 10.2.

The TVV provides a visual representation of the aircraft flight path, indicating where the airplane is going, which is not necessarily where the aircraft is pointing.

You can do the slide in option.   You do NOT need an inertial input - the 550 internal ARS (attitude reference system) provides that.  If you do not have heading input then you do not get the TVV (total velocity vector) symbol.  That's all you miss with no heading.

I'm a TVV junkie.  I don't care where my aircraft is heading, I only care where it is going.  The TVV shows that.  

But, I have a 3000+ hour HUD TVV bias here.   For those who have not seen a TVV in operation, you will be able to continue to fly  safely in blissful ignorance (not a bad thing at all).  Clearly, you can fly an aircraft safely without the benefit of a TVV.  Until, at least you see, and become, a TVV junkie and then you'll never be able to shake the addiction/habit.

Could I ask what's happening to the traded-in IFD540s? Will Avidyne just rebuild them as IFD550s? Or will they be re-sold as "certified refurbished" IFD540s?

I have flown a number of airplanes with the TVV installed and the only time it's made one dot of difference to me was when I was getting a type rating and had to fly steep turns.  Keep the TVV on the horizon and you would not climb or descend.  I have not had it tied to synthetic vision, though, so there may be some additional benefit (like seeing the runway on an ILS in a crosswind?).  If most of your flying is cross country you will get some interesting, but mostly useless, information from the TVV.  Just my 2 cents.

Put the circle on where you want to go, and the plane goes there. You can fill in any number of tasks there, whether level at cruise, or maneuvering.

Together with the SV provided actual horizon, and the pitch attitude, the TVV (FPV) will by difference show you your Angle of Attack, right on the PFD, or in this case the 550.

Respectfully. I don't think that is correct, Orest.

That's why I installed an AOA indicator.

Avidyne, a built in AOA, like Aspen has done for their PFD and MFD, though derived, could be a useful add on for the 550.

Just saying...

David I agree with you. What it will be displaying is you pitch angle relative to the horizon in straight and level flight. It will not show your angle-of-attack.

Ha! I have you gentlemen.

Although the AOA is not shown discretely, the AOA is easily discerned as the angular difference between the pitch attitude and the FPV (TVV). That is really the definition of AOA.

I use this all the time (with my ASPEN) to keep a constant AOA in a long climb.

A drawing makes it more obvious.


The 74 is shown in a climb here, the pitch attitude is Theta, the FPV is V-infinity. The AOA (alpha) is just pitch - FPV, which is pretty easy to read off the PFD. For example, if your pitch in the climb was 15*, and the FPV shows as 11*, then your AOA is 4* (EDIT).

Orest,
Fascinating... OK I am trying to follow your logic - I assume you meant 15-11 = 4 deg, not 3 for AOA in your example.

So, next flight, I will observe the FPV (TVV) on my Aspen PFD with SV and hold a constant AOA delta ("Pitch - FPV") in the climb. 

Wonder how holding a constant AOA in the climb will compare to holding a constant IAS, like Vy speed (which admittedly will decrease slightly with altitude).

Yes, typo, should be 4*.

After second segment climb, when you transition to cruise climb, note your displayed AOA. Maintain it, and you will maintain the same performance profile all the way up.

Your Vy will decrease 7 to 8 knts to the mid-teens. You can do the math, or just follow your PFD (or IFD). You can maintain Vy, Vy + 20, or whatever, using this AOA aid.

If those assertions are true, why do airliners have AOA vanes?  If it is a simple subtraction between fight path and pitch, doesn't make sense.  

The definition of AOA is delta between wing incidence and relative wind.

The two may be close in normal flight regime, but not sure they are identical.

EDIT:  Does the aspen depict FPM numerically?

If true, though, Avidyne can have its own AOA just with what is present.  Is that how Aspen did their (derived) AOA?

OK, now I can see that AOA can in fact be calculated from the TVV vs pitch. Thanks for the clear explanation O. I learned something today!     :-)

It is just a bit of math.

An AOA vane measures the AOA (relative wind) directly, and more accurately. Obviously preferable. Although the data is used internally, ironically, it is only a minority of civilian transport aircraft that show raw AOA.

No, ASPEN does not break out the AOA into a numeric value. But, I suspect that is exactly what they are using, in deriving their AOA values, with some smoothing added, and displayed relative to a reference point established with the fairly extensive flight testing required as part of the install.

If I was going to install a stand alone AOA system, I'd get the Safe Flight system.

Well, the Aspen AOA must have more... shows AOA in unusual attitudes like steep banks also, which must be beyond just the TVV.  

I will pay much more attention to the TVV practicing my Commercial Maneuvers... 
Great forum - Thanks Orest.   I always learn new stuff here.

The point of all of the standalone AOA devices is not to derive a number as discussed here, it is to determine the critical alpha for a given wing set, then alert the pilot when that alpha is approached.

I suppose you could take your 47 in level flight and calculate an alpha value for a near stall and use that number as a guide.  In the case of my AlphaSystems device it calculates differential pressures on a pressure vane and compares the current value of differential pressure to that identified as critical alpha.

I agree with Tom, always learning which is good.

Best to all.

My pleasure. It is an unhappy day for me, when one goes by and I don't learn something.

A couple of weeks ago, I ordered my IFD540 and APX340 plus the MLB100 and the installation will take place in a few weeks.  I think that the IFD540 is (more than) adequate for my current needs, but I don't want to be stuck with yesterday's sweetheart when it comes to future added features and improvements.  That places me pretty much on the fence regarding Avidyne's prepaid upgrade offer and searching for input from others who are more experienced than I am.  As is the case for most, budget is a consideration but I certainly don't want regret a decision to not upgrade under the current offer.

The 540 is a huge step up from my current Collins Microline with a IIMorrow GX-55 with GPSS.  I've spent quite a bit of armchair time with my iPad and Avidyne's free simulator and feel at least moderately grounded in its use and can easily envision using the new stuff in my plane.   I also saw the very helplful matrix above that details the major differences between the 540 and 550 including ARS.  However the topic is new enough to me  that I may not yet fully appreciate what the differences mean to me.

My plane currently has a S-TEC Series 30 autopilot with altitude hold and GPSS.  I understand that the 540 will play nicely with it.  I'm considering an autopilot upgrade at some time in the future once the bank account has had a chance to recharge.  Maybe to a S-TEC 55 or equivalent to get the benefits of coupled approaches, preset altitudes and so forth.  Does the IFD550's ARS give more meaningful inputs to the S-TEC 55 or is there no advantage there?  

My Cessna 195 benefits from "help" in the area of pitch control as well as roll control.  It's not particularly stable in either, although the current autopilot has taken care of both for cruise flight.  I'm anticipating that preset altitudes, ILS/VNAV tracking and other similar modes would be pretty coarse without attitude based inputs, but I've heard that the 550 may not be the solution for that?

With current history, performance, and bandwidth, I would NOT buy a 550 anticipating the 550 to do anything more than drive the 550; i.e., not serve as AHRS for an autopilot.  I suppose Avidyne could do that, maybe are even planning to do that (I doubt it), but within any reasonable timeline?  They don't have the bandwidth to complete current <<overdue>> projects.  With the draconian cert which would be required on top of that?  Nooooooo sir.

With the modifications coming to the "newer and friendlier" FAA, more likely you in the future might buy one of the whiz bang APs which are either in or coming to the EXP world.  That likely would have its own AHRS.  (and would cost you maybe a LOT less).

It is just my opinion, mind you, but my suggestion based on the appearance of the avionics world, keep the 540, keep the STEC 30 (don't buy the 55x), and wait and see what comes onto the market in the next 2-3 years.

You'll love what you already have, and you will have a $$ war chest for when the next generation of new goodies hit the market.
