MGL Avionics User Forum

Hello All,

As my Sonex project finally nears completion, I'm able to start testing it in real-world scenarios. During a recent taxi test, I noticed that the EFIS was displaying 2 Alarm messages - one in a larger display format (which I defined via the screen designer), and one in a smaller format. Here's a still image I was able to pull from the video of the taxi test:

When I got home, I found that I was able to duplicate this behavior using the latest version of the MGL Sim/screen designer - as you can see in this screenshot:

In the flight module, I have a single "Alarm message field" defined. No other alarm field is defined in this module:

However, when I load up other modules (such as Engine or Fuel), there does appear to be some kind of default alarm message field? I can not select or remove this item, and it doesn't show up in the list of "Items in current module" when using the screen designer mode:

I looked at the EFIS configuration and settings screens, and cannot see any option for modifying or disabling this smaller/default alarm message field.

Has anyone else run into this? Does anyone have a way to remove or disable the second/default alarm message? I much prefer the one I've specified in my flight module (i.e. size, font, and location)... Any help would be greatly appreciated!

P.S. I've got a nearly 100% MGL Panel: The primary instrument is a Discovery Lite connected to an RDAC-XF-MAP, SP-6, Trig Xpdr (with MGL CAN adapter), SP-12, and V6 Radio [I bought all of this a few years ago when the V6 first appeared, as I thought I was much closer to first flight... d'oh!]

Yes each screen has a default alarm message field. The system will suppress this if you define your own in a screen design.

There is a small catch - the presence of your own alarm field can only be detected when a screen draws for the first time. If your alarm field happens to be jumped over by a skip instruction then the system will not take this into account - if the condition for the skip is then no longer valid you will see both alarm fields.

So check your screen design drawing order list (on the left) and pay attention to any skip instructions and the number of items to skip - make sure you never skip over an alarm field or for that matter something you don't want to disappear from the display unintentionally.

Ah, this explains it! For some reason, I thought that I needed the "Conditional skip Item" field with the "No alarm active" condition in order to hide the Alarm message field.

Much appreciated,
