Just a thought especially today....how about an automatic local time offset option? Additionally, local time ETAs would show correct local time ETAs even if ETA fix time offset is different than current position time offset.

That's why we have UTC (Universal Coordinated Time)

Our IFDs (and maybe the IFD100 soon) have the ability to offset UTC by a fixed amount on a per user basis. I was trying to gauge interest in an automatic option for this offset. Currently, if one would like that offset to reflect local time, they would have to manually change that offset value every time they cross a time zone or when going in or out of DST (for each affected user). 

Thanks for pointing out that UTC would be required data for this calculation.

Excellent thread started by Steve!  Lots of great suggestions.

Bummer about Avidyne's interpretation of the regs on installation of firmware updates vs data updates.  Seems the wording from FAR 43 (as quoted by AzFlyer and HenryM in the "Update-on-10-2-3-1-software" thread) would allow, though maybe the local FAA rep implied otherwise.  

Maybe, to get this one to us, he (we?) needs to start another thread for the NEXT update...  

As one who chose Wing X over Foreflight a long time ago (and relieved that Boeing spared Wing X), sure glad for Garmin's foray into data:  Competition reduced the Jepp subscription price for us.  Still would prefer an alternative to Jepp.

AVIdly anticipating this release!
Thanks, Steve, et al!
Be happy! Your choice.

To underline the disappointment about no RF leg capability, in
Europe SESAR is funding a project to demonstrate that GA aircraft can successfully fly non-standard approach profiles including RF legs.  The selection of participants was limited to those with GTN boxes at software v6.21 or above. The flying is due to start in April or May. 

What a shame Avidyne is not at the party

Got an IFD being installed this week but got to fly a neighbors plane equipped with a 440 this morning and work an IFD for the first time. I was very impressed with it as I was able to do all functions by myself with no help and no manual. Really user friendly and intuitive. One suggestion, on simple direct to flights it would be nice if the IFD remembered last leg entered upon startup this way you could put your next destination prior to shutdown. May not seem like a big deal but helpful when you have multiple devices to set up making for an extended run up. Yes, I do know you can save as a prior flight plan but it's still easier if you don't have to touch it at all (except for allow/ignore).

Congrats on the new install!  It certainly is a great box!

In regard to remembering the last leg upon startup, I prefer to start with a clean slate.  Things can change between shutdown and startup on how I’m going to fly.  A clean slate has me be very deliberate about my route right before takeoff.  The primary function of the IFD is to support IFR flight plans, this is a VFR point to point request, which I think will actually hinder IFR operations.  Some things to consider:

·         Most of the time, I’m not sure what my next route or waypoint will be upon shutdown, so this feature will rarely come into play.  Also, after shutdown or before the next flight, I can always put waypoints into the IFD100 for auto loading when connected to the panel IFD.

·         When flying IFR, upon shutdown, the IFD will retain the last route flown.  Then on startup, I no longer have the option of just entering a route on the FPL page.  I will either need to delete the old waypoints while entering the new, or I will be relegated to entering everything new in the ROUTE page.  It limits my options and will cause extra work.

·         Upon startup now, I can do a database update in less time than it takes to warm up, taxi, and run-up.  Loading a single VFR waypoint would be simpler and faster than that.  I think you will find no extended run-up is necessary.

I am left to conclude that for most IFR operations, this feature request would be a hindrance.  Also, it will only come into play when the next VFR flight and waypoint are known, which is probably not very often (at least for me).  Even then, the IFD 100 will certainly suffice.

I know it's well over a year away, but it would be nice to have confirmation from Avidyne that support for RF legs won't have any more implementation restrictions than those for the Garmin GTN. Specifically, per the AFMS the GTN is approved to fly uncoupled RF legs ... i.e. does not require an A/P or FD.

Suggestion for 10.3

I fly a small experimental.  While on autopilot, tracking the GPS, I often get a popup message saying to adjust heading to xxx.   (Turn to xxx)   My autopilot is flying that xxx heading + or - a degree.  (I know the bigger stuff like the Pilatus I fly, is dead on and this isn't an issue.)   What would be nice would be a setting to loosen up the trigger for that popup alert by an extra degree or two.

Thanks

It may be telling you to set the OBS course to that value.  Mine does that for my CDI if I don't twist it.

As David mentioned, I don't think this has anything to do with how well the autopilot is tracking; the IFD is simply detecting where your CDI is dialed in and reminding you to update it if it's not dialed in to your desired course.  

In my plane, as long as I'm "close" (maybe +/- 3deg) on the CDI, the IFD is satisfied and will clear the alert.

Regardless of where the CDI is set, my GPSS-driven autopilot is dead on the magenta line when the IFD is in GPS mode.

That is what was happening in my Aspen/IFD540 panel.  I didn't realize that the IFD was prompting me to set the heading on the Aspen until now.  Thanks for that insight!  I flew yesterday and that is exactly what it was prompting me to do. Another IFD mystery solved.

OK thanks,   Yes, once I set the heading on the CDI, the message went away.   I rarely bother adjusting the CDI heading on my experimental, as I set the heading on my EFIS.  The heading on the Pilatus EFIS apparently is connected back to the 440. 

Learn something new everyday.

Lots of misuse of the word "heading" here.  To be clear, it is the CDI "course" that is being set.  The 'other' thing with the knob.

Don't know if this has been suggested already. Apologies if done so.

On flying a procedure, it's terrific to have the altitude necessary to cross the fix.  Add a field that would show the distance to the next fix.
I think that would be very helpful for situational awareness and enable us to stay on the same screen.

Those two data quantities are shown simultaneously on the FPL page already, per leg.  If you're trying to stay on the Map page, then I would suggest configuring one of the datablocks to show distance to the active waypoint.  Then you could see distance to the waypoint in the datablock and the crossing altitude would be displayed on the map (but both visible at the same time; subject to map decluttering).

Is it possible to make it optional for the IDF440 to NOT power up when the master is turned on. Make it optional. I would like to beable to power up my avionicas after engine start.

I could be wrong but I thought if you power down the 440 by pushing the button it will not power up with the avionics master but by pushing the button on the IFD again when ready.

AviSteve,I see that the IFD will network with a portable stratus. Will it also network with a Garmin GDL50? It would be great if the ADSB data from the portables would be able to display weather and traffic on the IDF100 app. Is this possible?

Not exactly true. Using an Avionics master continually will make the individual switch's and knobs on your various avionics become sticky unless exercised now and then.

Not really. Not good for the indivual radio, and sets up a very nasty single point of failure. if The master switch fails (and switch's do often fail) You could be truly in a world of hurt as you just lost all your avionics in one swoop. This is why you dont see avionics masters in combat aircraft.

My Mooney had a "fail on" avionics solinoid master which pretty much solved that problem.

+1 on the avionics switch, saves wear & tear & time. Some of my electronics do not have an ON/OFF switch, and would come on for engine start, not a good idea.

My avionics switch (when OFF) energizes a relay, which opens a circuit, and will cut the power feed to the avionics bus. If the switch fails, then in fail-safe fashion the avionics bus goes live.

I also have a guarded, backup avionics breaker/switch under the panel that will supply power to the avionics bus from a separate circuit, just in case.

Both were factory, and that is a fairly standard setup.

That all would be a pain to install. If you don't have an avionics switch, then just installing two switch/breakers in parallel to feed the avionics bus should work well, and be relatively fail-safe.

Not true.  It wakes up every time power is applied, regardless of the shut down method.
 
As discussed here, I was motivated to install an avionics master switch after the IFD installation for this very reason.

May not be possible with Avi architecture but presumably there will be more cycles of updates, and the current pathway leaves much to be desired.

Regarding audible call-outs while on instrument approaches - I think these would be EXTREMELY VALUABLE. Especially on approaches with multiple step down fixes.

If it’s easier to program, a simple tone (a ding, a bell, whatever) would be fine as well to let me know I’m crossing the fix. 

Having said that I just got my IFD 540 upgraded (it has been unchanged since it was installed in 2015). I’m going to try using the IFD 100 on my ipad during an instrument approach to see if that makes fix identification easier. It may.
 
My preference on instrument approaches is the have the approach plate on my iPad in front of me although I don’t trust the iPad fix locations (it’s not a certified WAAS navigator for instrument flight).

I’d rather watch the plate on the iPad but have the box “ding” or tell me when I’m crossing each step down fix.

Any chance we can get something like this?

Or do I have it already and just don’t realize that yet?

I’d like to see the aircraft stay centered on airport taxiway charts as it proceeds along. This was a nice feature on the EX500  airport charts but on the IFDs, it’s necessary to keep moving the chart on the touch screen to follow the aircrafts progress and keep it in view.
