Optimum thermalling speed display
With all the new (and some of the older - SN10 for example) vario-computers having accelerometers and settings for ballast and polars, would it be possible to compute and display the optimum thermalling speed adjusted for wingloading and bank angle (as a function of instantaneous G-loading)?
Since we don't (yet) have AOA gauges (which would do a better job of indicating the correct speed to fly in a thermal), I'm curious if a simple "speed to fly" indication would work.
Obviously, filtering a constantly varying G-load would have to be employed, but I'm thinking of a 2-3 knot speed band display - using the same fast-slow indicator used for cruise speed control - preferably also with a deadbeat digital readout of the optimum speed to thermal for an average of the past 3 seconds or so of turn/averaged G.
Would this work? Probably only once established in a steady, smooth turn - but that would give a good starting point for the next thermal.
