Tie down rings on or off.

Hi all,
During preflight do you remove your tie-down eyelet's? Check the POH under Right Wing and Left Wing preflight. In both areas the POH says Tie-Down - REMOVE eyelet. I am thinking that the...

Fuel valve on or off?

Hi All,
When you leave you aircraft at the end of the day, do you leave your fuel valve on or off? Why.
Thanks,

How hot is it?

So, the air around the carb filters is hot because it is at the back of the engine. I get that. But, how hot is it? Did Van's put a temp probe near the carb filters during flight testing? I think...

Scott,
Just now looking at the POH REV 7 and it seems VNE is both 136 Kts TAS and 136 kts IAS. That can be a little confusing. I suppose one should respect the most limiting of the two speeds. I...

Let me read this back. Aeroelastic dampening decreases with gain in altitude. Structural dampening mostly remains constant. So Vf (velocity flutter) decreases with altitude. Is this correct?

So, the lack of air resistance over the airfoil can lead to flutter. And that is why we may have a lower TAS VNE at altitude. Did I get that right? Thanks Scott.

Why is VNE TAS in the RV-12

I have looked at a few Type Certificate Data Sheets. Velocity Never Exceed (VNE) is usually listed as an Indicated or Calibrated Airspeed. Why is the Van's RV-12 VNE listed as a True Airspeed?

MP vs RPM

That makes sense. In a normally aspirated engine you loose 1in per 1000 ft of altitude gain. Taking off above 3500 ft you probably could not generate enough Manifold pressure to get into the shaded...
