I think that was associated with idle approach VS full throttle takeoff and cruise throttle.
Now that you mentioned, it makes sense.
No, we model low oil from repeated use. I think we add some random water also.
We don't record all the properties associated with these two systems (oil and carb ice) but we do record coughing, and it was definitely an event associated with coughing. It got severe right as the engine shut off. I looked at the property tree and didn't notice enough of a change in oil pressure or EGT to think it was oil related. But it appears that we don't record the icing numbers only the engine status.
I'll appreciate any heading/direction as to where to start looking to add those values in the log
That's why that carb heat is there and is to be used on approach if there is any doubt about conditions. Really, always use it on a long approach is a good rule of thumb I think.
I'll add this to my pre-flight checklist. Thanks!
