Let us enjoy by gradually progress!
Let's continue that way then

Other types of engine failure are engine fire, engine stall, chip in oil or oil pressure drop, as we see in previous post.
Engine model in our simulation is very complex, as well as other systems, there are many other features implemented in the code that could cause a failure or could be set as a failure in the ME.
Nice. A couple of questions.

Just did a quick read to see what can cause compressor stall ...
- foreign object damage such as bird strikes
- engine mismanagement
- extreme maneuvering
- engine icing
- poor maintenance

Does the simulation take any of these into account (other than maintenance)?

Also, will chip detection eventually lead to an engine seizure?

It takes into account engine mismanagement, if you exceed engine ITT in the case of the EB, or if you do not move slowly the throttle when engine computer is off.
Chip detector is one of the consequences of the above described case of stall if you persist in the engine mishandling which can lead to an engine fire.
I'm planing to add engine seizure with chip detertor on.

Bird strike in DCS, need to analyse how that interacts with our module, I don't know if it's included in the damage model. A hit with a bird should cause a damage in that part of the airplane I guess.
Engine icing: need to investigate it because it was working in SFM and not sure yet if it's correctly handled in EFM. We have it included in the code, but there seems to be an issue interacting with DCS.

I wouldn't bother with engine icing if I were you. Right now the atmosphere in DCS isn't simulated realisticly anyways. It acts as if it were always saturated in water, giving you icing warnings even though you're flying in perfect clear conditions, far from any visible moisture.

Yes, I know. We have simulated ice accretion level depending on the temperature range (OAT) and weather settings in ME. So if you fly in a mission with thunderstorms of snow you will get ice rapidly, and engine will fail if you don't use anti-icing and continuous ignition, at least when we had SFM, we need to solve it for EFM. Not totally realistic, but it's at least a way to try to simulate it.

Two thumbs up for this
