Complex alarms

[Battson]

It is possible to, or does Dynon have plans to release, 'complex' rule based alarms as a configurable option?

It should be straightforward to program, given the pre-existance of the current configurable alarms which must use some of the same logic.

What I want to do, is set a simple rule such as
"IF parking input signal = 1 (e.g. parking brake = On) AND Oil Pressure > 30 (for instance) THEN show Alarm1"
e.g. alarm text Remove Park Brake Before Landing.

If you had an EMS and EFIS system linked, it may be possible to go straight to airspeed instead of using oil pressure (in this example).

That would be really clever, and would provide a really open avenue to improve safety in many ways!

Not an impossibility, but it's not high no our priority list either. We try to balance power user features and complexity against flexibility against ease of use, and this is a feature that tilts a little bit towards the side of things that would make a few geeky* people (*like most of us here are) really happy, but it might not get the adoption to make it a worthwhile development effort against the huge list of other requested features.

I haven't seen this in the manuals, so please excuse me if this capability already exists:

I think a very valuable addition to the alarm function would be the ability to cancel an alarm and reset for additional faults.  For example, a CHT exceeds limit, so the caution lamp illuminates.  Pilot acknowledges by pressing a button and the light goes out.  If, while working on resolving this fault, a fuel pressure problem develops, the new alarm would re-illuminate the caution lamp, immediately drawing the pilot's attention to the new problem.

Assign an unused input pin on the EMS as "alarm reset" and code the alarm subroutines to accept the reset, ignore the original fault item until it goes back within established parameters, and resume monitoring all others for alarm conditions.

Yep, it does this. The light flashes on a new alarm, then goes solid when the condition exists but the alarm has been acked/viewed, will start flashing again if a new alarm fires.

Great! I presume acknowledgement is done via SV softkey, rather than having to wire an external pushbutton...? Thanks.

Yes, by pressing the button above the flashing CAUTION or WARNING button, you've ack'ed the message. See the Pilot's User Guide for a fuller description.
