So I'm getting familiar with my "new" (1978) J and on my 3rd time flying the thing I'm having autopilot (and / or Aspen) issues. The autopilot is a KFC-200, GPS is a GNS430 and there is an Aspen Evolution Pro. The Aspen appears to be working fine and when pressing buttons on the autopilot (FD, HDG, etc.) the appropriate setting is illuminated on the autopilot annunciator panel but the autopilot will not engage for NAV, ALT, HDG or anything. It behaves in a manner as if I were holding my finger on the CWS button. If I press the GA button I no longer get command bars on the Aspen. Big clue: there is a red light on the panel that is now illuminated labelled, "A/P AHRS FAIL". I am guessing this airplane has an EA100 adapter and it is this that has failed. Anyway, thought I'd reach out here to see if there's anything I can do before taking it to the shop and spending $$$. (On a side note it looks like the previous owner took out an extended warrantee on the Aspen, which hopefully covers all components, so I'm not crying just yet).
I have the EA100 adapter as well and it failed in flight about two years ago. I hand flew the plane the rest of the trip and after shutdown I fired it back up again and the light was off. I flew the plane the following day to troubleshoot and it worked perfectly and never failed since. It would be interesting to know if others have had problems with this adapter.
I had a similar problem not too long ago.I have the aspen as well, and in my set up the auto pilot gets its attitude information from the the AHRS which is part of the Aspen. The AHRS is made by Aspen and is actually a separate box behind the panel. In my case, the AHRS fail light illuminated, and the auto pilot, a KFC 150, would not even go through the self test. Once the AHRS was swapped out, which my shop was able to get done under warranty, everything was back to normal. Hope this helps.
That failure light is associated with an issue with the EA100. You didn't mention how you are engaging the autopilot with respect to the GPSS from the Aspen. If you hit the HDG button on the autopilot can you control turns using the heading bug on the Aspen? Is GPSS used at all? On my STEC, I would normally in HDG mode prior to going to Nav mode. My definition of "Nav" mode is leaving the autopilot in HDG mode and engaging the GPSS feature. Tell us more about how you are using the autopilot buttons.
Prior to yesterday, pressing HDG and enabling the autopilot I could then twist the heading bug on the Aspen and the autopilot would behave as expected. I've been reading the EA100 documentation and if the A/P AHRS FAIL light is illuminated it will disconnect the autopilot so the symptoms point to the EA100. When I'm at the airport next I'm going to try an AHRS Reset on the Aspen, and pull the panel off and check the cables if it's still not resolved. I just spoke to the previous owner who confirmed that it's still under warrantee so I'm happy (relieved) about that.
The avionics shop has determined that the issue is a faulty Aspen EA100, which is being swapped out under warranty. After less than a month of ownership of my "new" J, this has persuaded me to extend the extended warranty...
Folks, resurrecting a thread here. I have a new Aspen Pro and my KFC 200 interfaced by the EA100. We test flew yesterday and found that the AP would engage, but any correction (even 1 degree) would cause a turn of 45 degrees plus immediately. Obviously we were disconnecting prior to this happening, but pretty scary. My avionics guys are working on it, but has anyone else experienced this with the EA100? Thanks, Mike
Tim, I had a similar problem with my AHRS light illuminating after a couple of hours and the A/P kicking off. My avionics shop called Aspen and the Aspen rep had me go to a diagnostic page and take some pictures of the display. One of the gyros was drifting beyond tolerance and the PFD display unit had to be replaced. (These may not be the exactly correct technical terms for all of you avionics gurus, but you get the drift. The little doohickey was all cockamamie.)
Aspen PIMS, Aspen Petroleum Scheduler, Aspen Plant Scheduler, Aspen IP.21 Process Browser and other solutions for optimizing production and supply chain are available in Russian. They complement the extensive product portfolio of aspenONE Engineering and aspenONE Manufacturing & Supply Chain, which have already been translated into many languages, including Russian.
In addition to Russian, the programs of the aspenONE V7 package have Chinese, French, German, Italian, Japanese, Korean, Portuguese and Spanish localization. AspenTech customers can download language packs from the Support Center - AspenTech Support Center page.
On November 30, 2021, AspenTech, a global provider of software to optimize asset performance, announced the availability of the next version of aspenON software. Release V12.2 provides companies with additional sustainable development models and product capabilities that accelerate digitalization to support their sustainable development initiatives.
The aspenONE V12 software now includes more than 50 models, including models to understand where production efficiency can be improved to meet CO2 reduction targets. Using these models, customers will be able to determine how to reduce emissions throughout the value chain, reduce energy, water and raw materials consumption, switch to other energy sources such as biofuels and hydrogen, and provide a closed-loop economy through processes such as plastic processing and turning waste into chemicals.
In addition to models for sustainable development, version V12 includes a number of upgraded products and capabilities designed to provide ease of use, accelerate business processes and actions for effective collaboration throughout the value chain. These include:
On May 25, 2021, Aspen Technology introduced an updated version (12.1) of the aspenONE software package. The company AspenTech introduced industrial artificial intelligence in its leading solutions to increase the profitability and sustainability of customer processes. Industrial AI Workbench provides opportunities to collaborate with industry experts to develop AI-based applications for enterprise-wide data.
Thanks to hybrid models built on basic principles, artificial intelligence can be directly used in process modeling using Aspen Hysys and Aspen Plus. This facilitates the development of operational models and their calibration using production data. Lower-order hybrid models can be used in engineering, planning, and dynamic optimization systems to improve accuracy and predictability of results. The Deep Learning Manufacturing Process Management (APC) solution helps you create more accurate and sustainable models that meet a wide range of performance requirements. The combination of these capabilities allows you to achieve a higher level of operational efficiency.
aspenONE 12.1 provides models that help customers optimize biomass processing, hydrogen production, carbon capture, and carbon footprint with more accurate systems solutions that reduce environmental impact. Available analysis and imaging capabilities reduce waste and energy consumption at all stages, from research to production.
