Hi Paddy,
I agree with everything you say here except the bit about the turbulence because
if the wind speed (relative to the aircraft) changes rapidly, the talking ASI
will pick that up as quickly as the AoA instrument does. As you point out, the
real benefit that AoA gives over airspeed is the detection of the
accelerated stall. It did occur to me during development of the talking ASI that
by adding an accelerometer the widget could take into account the higher
loading.
Perhaps I should investigate that idea further.
I've said enough now, everyone must be bored to tears.
If anyone wants to discuss the talking ASI further, please send email to
enquires@smartavionics.com
Regards,
Mark
