The article “Slow Down, You Move Too Fast” (January 2011) was enlightening. While Mr. Gibbs statements are logical, it would be helpful to have a reference describing this in more detail. Would you please provide a reference that explains the aerodynamic theory or aircraft certification process that substantiates Mr. Gibbs explanation? Although I find Aviation Safety very useful, I cannot use it as a 288
Never Exceed Speed
The article "Slow Down, You Move Too Fast" (January 2011) was enlightening. While Mr. Gibbs statements are logical, it would be helpful to have a reference describing this in more detail. Would you please provide a reference that explains the aerodynamic theory or aircraft certification process that substantiates Mr. Gibbs explanation? Although I find Aviation Safety very useful, I cannot use it as a sole reference when providing instruction.
Key Takeaways:
- Readers expressed confusion and strong skepticism regarding an article's claim that VNE (Never Exceed Speed) is primarily True Airspeed (TAS), contradicting common flight training and official aircraft documentation (POH/TCDS) which typically state VNE as Indicated Airspeed (IAS).
- The magazine acknowledges that while VNE is often published as IAS for simplicity, it can be more accurately expressed as TAS, especially for aircraft operating at higher altitudes and speeds, where thinner air reduces damping against aerodynamic flutter.
- The editor advises pilots to always consider the more conservative VNE value when presented with both IAS and TAS limits, emphasizing the importance of critical thinking to maximize aircraft use while minimizing risk.
