Steady flight, unaccelerated flight, or equilibrium flight is a special case in flight dynamics where the aircraft's linear and angular velocity are constant in a body-fixed reference frame. [1] Basic aircraft maneuvers such as level flight, climbs and descents, and coordinated turns can be modeled as steady flight maneuvers. [ 2 ]
Most aircraft trimmed for straight-and-level flight, if flown stick-fixed, will eventually develop a tightening spiral-dive. [2] If a spiral dive is entered unintentionally, the result can be fatal. A spiral dive is not a spin; it starts, not with a stall or from torque, but with a random perturbation, increasing roll and airspeed.
When flight conditions are steady, stability and control derivatives are constant and can be more easily analyzed mathematically. The analysis at a single set of flight conditions is then applied to a range of different flight conditions. Application in simulators for stability analysis
Used instead of V R (in discussions of the takeoff performance of military aircraft) to denote rotation speed in conjunction with the term V ref (refusal speed). [19] V Ref: Landing reference speed or threshold crossing speed. [7] [8] [9] Must be at least 1.3 V S 0. Must be at least V MC for reciprocating-engine aircraft, or 1.05 V MC for ...
A flight attendant revealed the secret meaning behind the airplane chime sounds you hear during a flight.
One technical definition is that a kite is “a collection of tether-coupled wing sets“. [119] The name derives from its resemblance to a hovering bird. [120] Kutta condition – is a principle in steady-flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies with sharp corners, such as the trailing edges of airfoils.
