There is a problem with that, the barometric pressure and CAS do not populate to the 540 automatically in most setups. As such, such a display would/could be in error.

Waiting in line for my new 540 install and getting familiar with the iPad App - I notice there is no DataBlock option to display True Air Speed (TAS). Only reference to air speed is the CAS in the Utility page.
Will the next 540 Upgrade please have a Datablock to display TAS. Thanks. Tom W.

Hi SteveWell, I finally got around to checking the software revisions on the Aspen. The MAP VER is 2.6.5, the IOP version is 2.0.5. Let me know if this makes any difference or if there is some setting or wiring change that would enable the heading bug and VOR course line at this sw level.

This might explain it if the unit was in track-up mode but it is not. It is in heading mode. Steve- Randy is still at work. Could you call him and discuss the problem? His number is 916-428-3392. Thanks, Jim |

Okay. We'll want to know what the User Options page item labeled "Map Orientation" is set to. The Pilot Guide snippet for that is:
Map Orientation Heading-Up* - the map will be displayed in heading up orientation if heading is available; Track-Up – the map will be displayed in track up orientation Note: Even though Heading-Up is the default selection, if there is no heading source, then the default reverts to Track-Up. Potential heading sources include digital heading from an ARINC429 source (e.g. EFIS), WX500, serial 232 heading source and, analog synchro heading input. And, here is a note from the Pilot Guide that may also explain the behavior being observed: NOTE Map Orientation Without GPS The map orientation will auto-switch from track-up orientation to north-up orientation when GPS is lost. Pilots who leave the map orientation in track-up during shutdown may notice the map will start up in north-up until a GPS position fix is available, at which time the map will auto-switch back to trackup. |

Steve, The install was done by Airborne Electronics at Sacramento Executive. Randy is my contact there and he says he will call you tomorrow. They are still working on the installation and I have not seen it yet. I am a bit confused about what it is doing but this is what I think it is. The IFD-540 display is north-up regardless of what is selected (n-u, heading or track). Nevertheless, the correct heading from the Aspen (arinc-429) is displayed in a box at the top of the IFD-540 display. The EX-600 appears to display track-up regardless of what is selected. Randy said that the other shop on the field (Executive Autopilots) also just completed an IFD-540/EX-600 install and had the same problem. -Jim |

Doesn't ring any bells with me. I use that configuration all the time in the test airplane (Aspen supplying heading to IFD540 and IFD540 map set to heading up) with no issues whatsoever.
When and who did your shop contact? Did they send datalogs from the 540?

Mike,
I am certainly in your corner regarding the need for Aspen to revise the manual. We are not going to accomplish that on this forum. It might be useful for your installer to speak with Tim and let them work out what can be done. If enough installers a speak to Aspen about this situation, they will likely revise the manual if there is no physical or electrical problem with doing that. I suspect that most folks at Aspen do not know about the capabilities of the IFD compared to the older generation Garmin radios. Jack

Thanks for your efforts. The problem is that the Aspen Installation Manual specifically says in at least two places that you must pull air data off ACU2 if an ACU is installed. There is no provision to access the pins directly unless there is no ACU. My installer will not go against a printed, FAA--approved installation manual. I don't think that the opinion of anyone at Aspen is likely to change his mind unless the manual is revised to permit this connection. It would really help if we could get Mr. McNany to get the manual revised. Thanks Mike |

Verified that I'm bypassing all ACUs in the Avidyne test airplane and that's why I've got a fully integrated heading bug on the IFD540.

Mike, and David,
I have been E-mailing with Tim after your post on 13 March. He indicated to me that he would be willing to talk to my installer and verify to him that the use of pins 27 and 28 can be used with the ACU installed. Tim stated to me that he is well known amongst the Aspen dealers, but he elaborated with:Tim McNany – Field Service out of California. So, I think you can have your installer talk to Tim and clear it up regarding the installation. Jack

My avionics shop informed me today of a problem interfacing the Aspen to the IFD540 and EX600. The heading data from the Aspen (Arinc 429 I believe) gets properly sent to both units because the correct heading is shown numerically on both units. But when "heading up" is selected on either display it shows some random orientation. The shop contacted your tech support about this and I believe they were told this has not been seen before. Do you have further insight into this?
Thanks, Jim |

I have tried both Honeywell and airdata/EFIS. Can't get a heading bug on the IFD540. (ASPEN + ACU2) I'm wondering if that data only "escapes" the ASPEN, when the 429 line is wired directly, bypassing the ACUx. * Orest Edited by oskrypuch - 14 Mar 2015 at 7:36pm |

I think so. I have mine set to Honeywell EFIS and I have a working and responsive heading bug. But I need to check on a few things on Monday since I think I have a non-conventional installation. Will post an update in a few days. |

My installer doesn't want to grab the 429 data off those two pins when an ACU is installed. I have the new Aspen Installation Manual (version BA). You are right, the text below Figure 3-2 is gone. But Note 2 on Figure 9-28A says you can only take the data directly off pins 26 and 27 when no ACU is installed. Does anyone know of any relief for that? VOR #2 and the autopilot are both connected through the ACU, so we have to have one. We'd like air data too but without the expense of an ACU2. Thanks Mike |

Question: If an Aspen is connected to an IFD540, can the Aspen be set so that it displays the GPS on the HSI bearing selector, and VLOC1 simultaneously on one of the two RMI needles? That is, does the IFD540 send both GPS and VLOC1 bearing info to the Aspen at the same time? Or is it just one or the other? Thanks Mike |

I have an Aspen + ACU2 wired to the IFD (as it was to the 530W before it). In my settings the ARINC 492 port connected to the ACU2's out is set to 'EFIS/Airdata', not 'Honeywell EFIS' as the install manual recommends. I think this is because we changed it from Honeywell EFIS to EFIS/Airdata when we added the ACU2 two years ago as that made the 530W pick up the new air data sources. When I upgraded to my IFD540 the installer just copied the settings from the 530W. I seem to get air data as I have a wind vector and VSR. But I see no heading bug on the IFD. I have Aspen's 2.6.5 software loaded as well as your 10.0.3.0 software on the IFD. Should I have it changed to 'Honeywell EFIS'?

Hi Steve
Thanks for the detailed answer. the IFD540 is set up for Honeywell EFIS. Ill check the software revisions, but the Aspen is new as of December of last year so it should be the latest revision of software. It sounds like to have the VOR course work Aspen has to do something to their software. I used to have an Apollo stack with GX60 MX20 setup that while very limited compared to the IFD/Aspen combination had this feature where the VOR radial OBS set on the SL30 was displayed on the moving map. It was very useful departing IFR out of LA, where they often give you departure directions to join a radial onto your filed course. this allowed you to see the radial easily on the moving map, improving situational awareness. I can use the Aspen bearing pointers, but its not the same as the moving map VOR line. If you can figure out a way to get this to work with the Aspen Id really appreciate it. I should say In general I'm very happy with the IFD540 setup with the Aspen. Although I had the install done late last year, I just had my first long flight with the setup. I flew it down to LaPaz Mexico and back from KLVK last week. IFR in the states and VFR in Mexico. I really like the interface and in general the system and software works very well. No regrets on the decision. I got the free transponder deal and have foreflight and a stratus 2, so looking forward to connectivity enhancements with wifi and bluetooth. Ben |

Congrats and thank you on the IFD540 purchase.
As part of Release 10.1.0.0, I will be publishing a clearer description of the VOR course line integration with the various EFIS's out there - many are slightly different from each other in behavior based on what they do or do not transmit/accept. This might be a little too gobbly gook for you but here goes...... You won’t get the VLOC course line using an Aspen. The Aspen stops sending the selected course data in VLOC mode as it resolves the course error internally by taking the difference between 429 label 0222 (VOR Omnibearing) and their course pointer. There’s no need for them to send the selected course over 429 to us, so they don’t. It works only with some EFISs that continue to send course data in VLOC, like the Sandel SN3308 EHSI. As for the Heading Bug, it has to do with how your installer has configured the Aspen and your IFD. We will only use the Aspen special label for selected heading if you are configured for Honeywell EFIS. Your Aspen may not support sending that data as it is an unofficial label we reverse engineered in 2.6.2 of the Aspen software. It’s actually coming from a message intended for their ACU to drive an analog heading output, although I believe we are an all-digital setup and that label 0105 is there. You or your installer should check that you are configured for Honeywell EFIS on your IFD, then report back your Aspen software information for the IOP (I/O Processor) and MAP (Main Application Processor). As for your Mx depiction of selected course, I’d have to look into it but I believe that is just the analog/OBS input, not the 429 input that gets routed to that field. |

I have a new install of an Aspen EFD1000 and IFD540. In general, everything appears to be correct but I have two features that don't seem to be working. I don't have a heading bug showing up on the IFD540. Which I think should be there, and should match the Aspen heading setting, and I don't seem to be able to get the VOR course depiction line as shown on page 5-10 of the pilots guide to show up either. GPSS works well, I have flown a WAAS autopilot coupled approach and everything works properly. Course waypoints are displayed on the Aspen, so data is going in that direction. With a VOR tuned on the IFD, I have a good ID signal and the Aspen will give me VLOC1, which is the IFD540, as a nav source, so its getting good data. It sort of looks like no course data is going back to the Aspen. I have called Avidyne tech support and the shop that did the install, but no answer so far. I was wondering if anyone else had seen this.
When I look at the IFD540 main inputs page in maintenance mode, I can see OAT data, so it looks like the Aspen is sending data to the IFD540 as well. However the values for the selected course in the main inputs page are all dashes. There is no response to spinning the course pointer on the Aspen. Any thoughts?

More news from Aspen. I have been E-mailing with Customer Support and the latest news is that there is a revision to the install manual which should help out the Aspen owners. Tim McNany sent me a message in reply to my question about connecting directly to pins 27 and 28 with an ACU also installed. His response: The one statement in the Installation Manual (below Figure 3-2) that prohibited the direct connection to pins 26/27 has been removed in Revision BA. This revision will be available within a few weeks so your installation in April will not be a problem.

I checked the Aspen install manual.
Air data can be picked off PFD pins 26 and 27 IF NO ACU, but apparently not if either type ACU is connected and configured. Options for those of us with an ACU are to use GPS data in 10.1.0.0 or change ACU to ACU2. |

Thanks, Steve. That explains why I'm not seeing the any information in the datablocks for either the winds aloft or VSR. I'm sure my Aspen EDF1000 Pro, which was installed in 2010, only has ACU1. Rather than going to the considerable expense of switching to ACU2, I think I'll just wait for Avidyne to release Software 10.1.0.0, which will allow these features to work (along with Advisory Glideslope) in the absence of Baro Alt information. When this spring do you think that will be? Mike

It is physically possible to do that, but I have been told that that interconnection is contrary to ASPEN's STC. Whether your shop will do that or not, is up to them. It is highly unlikely that your wings would fall off. * Orest |

Steve,
Thanks for the information. Just to clarify. Nothing is easy... My airplane has the ACU so I would fall into the 2 lines which start with ACU. Is it possible to bypass the ACU and tap into pins 26 and 27 on the EFD air data directly? Jack

Another example of going beyond expectations.
One other item, though, Steve. With an ACU1 in place, can the other parameters be picked off the EFD pins, and if so, how to wire to 540(s)? And, if one waits and is Ok with WAAS altitude, will winds and VSR drive off WAAS altitude (I think your description said that 10.1.0.0 would do that)?

There are understandably a number of folks confused with why they do or do not have certain features on the IFD540 when connected to an Aspen EFD. I've tried to put together a summary table of the various Aspen configurations when connected to an IFD540. You can see there are three basic configs:
1. EFD only, no ACU involved 2. EFD + ACU (I called this ACU1 in previous posts) 3. EFD + ACU2 The ACUs are essentially a "happy box" or signal interface box. For features like VSR datablock and Winds datablock and Advisory Glideslope to work, the IFD540 needs baro input (baro corrected pressure altitude and TAS) among other things. You can see there are some configurations below that provide that data, and some that don't. The one that had most people wanting for more is Advisory Glideslope. If you don't have an Aspen configuration that supports it now (one that sends baro corrected pressure altitude), don't fret, that capability will come along "for free" with Release 10.1.0.0 in the spring. In that release, if we don't have baro corrected altitude, we'll use GPS altitude instead.
