Did you forget to activate the pitot heat while the OAT fell below 0 deg C?
Thinking the incident over last night, that was also the conclusion I arrived at. I honestly don't remember whether I did something to it on the ground as part of the checklist, but I probably did not.
The on-screen warning reads the indicated airspeed, i.e. the speed the ASI is showing
After doing some digging in the files, yes, I saw that as well.
We may have different philosophies here, but I guess that threw me off-track rather massively. My first idea was that maybe this is some kind of instrument malfunction, but since the limit check callout seemed to confirm what the instruments said, I decided to go by it.
I'm guessing in reality you'd have subtle sensory cues that an aircraft is getting overstressed - certainly in a glider you can tell from sounds, changed handling characteristics and g-forces that you're getting too fast, I'd assume there may be different vibrations in reality - same for stall warnings - and I've always pictured on-screen limit warnings as a stand-in for that as it's difficult to simulate.
Basically in the implementation, not only the instrument itself but also the on-screen callout gives you bad advice in the event of an instrument malfunction - so you need to be very sure you have diagnosed the problem correctly to not react in a dangerous way. That's perhaps not overly user-friendly - if the co-pilot doesn't give sound advice, I'd rather have him shut up rather than actively preventing me from flying safely.
That's also the way limit warnings work in the Shuttle - all warnings displayed on the avionics or the CWS matrix are based on simulated instrument readings, but all on-screen callouts are based on simulated truth (aka, there's no reason Mission Control or your Co-pilot should not be able to recognize an instrument malfunction...)
If you want to write an "official" review (e.g. for the website), would you mind to wait a few months with that?
I am fairly sure there'll always be a 'next project' - I don't think any of the planes which made it to the webpage were in any way 'finished' - it's mainly intended to get some attention and I guess users who like what they see will stay with the plane also for future versions.
