扑动动物飞行的传统空气动力学分析引用了准稳态假设；将动态问题简化为一系列静态条件；假设扑翼上的瞬时力与相同瞬时速度和攻角下稳定运动时的瞬时力相同。这一假设的有效性以及非定常空气动力学效应的重要性长期以来一直是有争议的话题。韦斯-福格测试了悬停动物飞行的假设，其中不稳定效应最为明显，并得出结论，大多数昆虫确实根据准稳态空气动力学原理悬停。研究了这一结论的逻辑基础；现有证据仍然不明确。
The conventional aerodynamic analysis of flapping animal flight invokes the quasi-steady assumption; to reduce a problem in dynamics to a succession of static conditions; it is assumed that the instantaneous forces on a flapping wing are equivalent to those for steady motion at the same instantaneous velocity and angle of attack. The validity of this assumption and the importance of unsteady aerodynamic effects have long been controversial topics. Weis-Fogh tested the assumption for hovering animal flight, where unsteady effects are most pronounced, and concluded that most insects indeed hover according to the principles of quasi-steady aerodynamics. The logical basis for this conclusion is examined; the available evidence remains ambiguous.
