Key Takeaways:

The magazine issued an apology and correction regarding its previous statement that V_NE (never-exceed speed) is a true airspeed, clarifying that for most certified aircraft, V_NE is an indicated airspeed, although the critical flutter speed is dependent on true airspeed.
It was explained that the slight 4% weight increase of G100UL unleaded avgas has a negligible effect on an aircraft's empty weight because this increase only applies to the small amount of unusable fuel, not the total fuel or aircraft's overall weight.

In your September 2022 issue, in response to Scott Burkhart’s email, you unnecessarily scare him by stating that V_NE is a true airspeed (for his Mooney). In fact, for him, and the vast majority of people who fly certified planes, V_NE is an indicated airspeed that is safe to fly (flutter-wise) up to the aircraft’s ceiling.

You had to walk back the “V_NEis a true airspeed” claim once before, in May 2011. Why shoot yourselves in the foot and have to do it again?
