Bench check of IAS moves compass heading

[Chris(Guest)]

Hi,

Have just received the D10A for installation in a Pulsar in New Zealand and it seems to work well on the bench before installing in the panel. However I noticed that applying air pressure to the pitot inlet that as the airspeed goes up the heading tape moves by 20 - 30 degrees. Is this expected and one of the reasons for needing to do a calibration in flight?

Also noticed that the horizon moves but see in a previous post that this is expected.

Otherwise the D10A looks superb and I can't wait to get it into the air where it belongs!

Hi Chris,

The EFIS does use airspeed and other available sensor information to improve the immediate performance and stabilize the magnetic heading. Your EFIS is behaving normally.
