Would it be possible to readout(voice) actuel airspeed when in the landingroll? Then I do not need to look at the instrument but can concentrate on looking out.

As George mentioned, this would be rather unsafe as GPS only knows your groundspeed and even this is sometimes subject to a little lag. It really isn't suitable for real-time tactical readouts of speed, which presumably need to be airspeed.

I quite agree but in theory could SD not calculate airspeed using GS and weather data from nearest winddata - wind, windspeed, windangle, qnh and heading? If so, how about testing that? I use Garmin GLO that updates GPS-position 10-times often than build in Ipad GPS.

Are there any instrument that could feed airspeed data to SD? I just want SD to be in the very front :-)
