airspeed correction

[ljbuller]

I know there is a way to adjust altitude.
Is there any way to correct indicated airpeed?
I will recheck alignment of the pitot tube, but assuming it is good can the airpeed be adjusted like the altitude?

There isn't, though we'll probably add a way to fix very low airspeed airspeed calibration creep which is sometimes seen over long periods of time. The D10/D100 has this in the form of the "zero airspeed calibration", or SPDCAL menu item, already.

The reason this is offered at all is that very low airspeeds (<20-30 knots) are basically thousandths of psi of difference, which are against the edge of detectability.

Mostly, though, IAS == dynamic pressure, period. The cause of most systemic IAS issues are problems with the static placement.

Re: airspeed correction/static placement

Does anyone have an opinion on the best place for static placement in a tube and fabric airplane. I currently have two, one on each side of my boot cowl, wondering if that is a bad placement.

HI Guys,

How do you adjust altitude?

A trick question, right ? ;D I just move the stick to change alt, maybe others do it differently

Du, I hadn't thought of that!! Clot!!

Perhaps the question was badly phrased! I reckon my SV is a couple of mb adrift, hence the question.

Off the top of my head (at Osh, not in front of a unit), I think it's under setup menu >hardware calibration > adahrs.
