Flutter uncertainty by the PCE method.
| One-dimensional polynomial order | Mean value for flutter velocity: m/s | Standard error for flutter velocity: m/s | Velocity range: m/s |
| 1 | 36.5 | 0.7835 | [35.0, 38.1] | 2 | 36.5 | 0.7840 | [35.1, 38.2] | 3 | 36.5 | 0.7877 | [34.9, 38.2] | 4 | 36.5 | 0.7987 | [34.8, 38.3] | 5 | 36.5 | 0.8137 | [34.5, 38.6] |
