I have a backup. When I tried to install it the PC application returned an error that it was not the correct file format. It was then emailed to Dynon support. The following was the response: I tried using your firmware backup and I also received the message that the file was corrupted. We...

Here's an update on this issue.  It has been confirmed by Dynon support that I cannot restore my firmware backup because you cannot go from a later version (5.4) to an earlier version (4.2).  I also cannot do a clean installation of 4.2 in the field.  This would "brick" the unit.  My only option...

The SL-30 is set to Resolver.

My setup is an SL-30, external Mid-Continent nav head and D-10A that replaced a vacuum DG. The Dynon defaults to EHSI mode. The EFIS functionality of the Dynon is a backup AI for a vacuum AI. I’ve had this setup for 5 years. The Dynon EHSI tracks the Mid-Continent OBS when a VOR frequency is...

Does Dynon provide access to earlier versions on the firmware?  I recently updated from 4.2 to 5.4.  As a result, I can no longer set the inbound course on an ILS via the OBS on my external nav head.  This function is more important to me than the other enhancements.  I'd like to roll back to...

I just updated to the latest software and am having the same issue that the OP noted. My setup is an SL-30, Mid Continent nav head and D-10A that replaced a vacuum DG. The D-10A defaults to the EHSI screen. Prior to the update, I was running software version 4.0 or 4.2 and the D-10A would...

I have a D-10A that replaced my DG and it is used as an EHSI. It is connected to an SL-30 and 296 via a nav source selector switch. When connected to the SL-30, there are two bearing pointers (active and standby VOR), along with two numeric readings of "bearing to" the VORs. The SL-30...

Did I hear someone say "flight director"? As someone with a D-10A, coupled to an SL-30, and an existing dual axis autopilot, is there any plan on offering the FD functionality without the Dynon autopilot and additional hardware?

Thank you. That was a ten minute response, after business hours, and on a discussion board. That's the definition of customer support!!!!

The release notes indicate that another variable (MAGINT) has been added to the EDC calibration.  Does this additional parameter increase the accuracy of the system?  Will an already calibrated unit benefit from a recalibration after a firmware update?  If so, where do I obtain the magnetic...

Thank you for the analysis. Regarding Option 1, you may be on to something here. Instead of shaving aluminum off the static port rivets, I'll start by stripping the paint and primer and then polishing them. I'll run flight tests before and after each change. The aircraft was painted with a...

Kevin, I’m confident that the OAT sensor is correct. The aircraft has two independent OAT probes, located on different parts of the airframe (wing and tail). One feeds the Dynon, the other a RMI MicroEncoder. They are within 1 deg C of each other. The accuracy has also been verified during...

I have Van's stock static kit, and static ports installed. A small TAS error can become a large error in wind computation. It would help the usability of the wind vector if we could input a table to correct this error.

A while back, there was a discussion on providing a method to calibrate the TAS being calculated. My indicated airspeed is correct at lower speeds, but at cruise, there appears to be a static error. This results in a slightly higher indicated airspeed and therefore the Dynon computes the wrong...

Jetjockey, Exactly what are you basing these claims on?  For the record, there are no established standards for trend vectors as you claim.  If you disagree, then please site a reference to an FAR, Advisory Circular, or TSO that mandates green for trend vectors.  One manufacturer's (Boeing)...
