Recently I was flying a 500ft circuit, when in the downwind leg I felt a buffeting, when I looked at my ASI, to my horror, I was at stall speed.
I recovered without incident, (recover might be an exaggeration, I don't think the stall developed), but it got me wondering, is there any app available (or can you add to SkyDemon) a stall warning alarm? Obviously the tablet can't detect AoA, so it would just be based on your speed vs stall speed, which you would need to set.
If not, what other options are there? This is in a C42.
To clarify, the Ikarus C42 does not have a stall warning horn
