Marginal stability is sometimes referred to as neutral stability.
2.
Some acrobatic and combat aircraft have low-positive or neutral stability to provide high maneuverability.
3.
For neutral stability conditions, \ alpha is approximately 1 / 7, or 0.143.
4.
The "'top figure "'shows relative contribution of the land surface area to the flux for two different measurement heights at near-neutral stability.
5.
The "'middle figure "'shows relative contribution of the land surface area to the flux for two different surface roughnesses at near-neutral stability.
6.
Even under neutral stability conditions, an exponent of 0.11 is more appropriate over open water ( e . g ., for offshore wind farms ), than 0.143, which is more applicable over open land surfaces.
7.
A Cessna 152 is an example of a stable aircraft . Similarly, an aircraft with neutral stability will not return to its trimmed setting without control input, but will oscillate in a stable simple harmonic motion around the trimmed setting continuously, neither increasing nor decreasing oscillation amplitude, and be susceptible to bank influences.
