Airspeed Error D10A

[deemsdavis]

I have a D10A installed as a backup EFIS, the Altitude and compass readings match exactly with the primary EFIS. However the Airspeed is indicating 250-260 KTS on the D10A (I only wish it were accurate !) when the actual is 135-145 KTS. I checked the pitot connection to the unit and it appears to be solid. I was under the impression that pitot leaks resulted in lower airspeed readings. what could account for this being so high?

Are you sure the D10A isn't set to display speed in kph instead of knots? 135kts is approx 246kph...

3 units now........ airspeed and ALT have all been 100% spot on..... compared to certified test equipment. Can't beat that!

km/h.........

We have all done dumb things before so don't let us poking fun at you upset you!

By the way have seen your plain pics..... Very Nice!!!

If you change both to kph, you'll go faster
;D

Yep, we've all done it!
