In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).
angle of attack α: angle between the x w,y w-plane and the aircraft longitudinal axis and, among other things, is an important variable in determining the magnitude of the force of lift; When performing the rotations described earlier to obtain the body frame from the Earth frame, there is this analogy between angles: β, ψ (sideslip vs yaw)
The angular velocity of the particle at P with respect to the origin O is determined by the perpendicular component of the velocity vector v.. In the simplest case of circular motion at radius , with position given by the angular displacement () from the x-axis, the orbital angular velocity is the rate of change of angle with respect to time: =.
Best rate of climb speed with a single operating engine in a light, twin-engine aircraft – the speed that provides the most altitude gain per unit of time following an engine failure, while maintaining a small bank angle that should be presented with the engine-out climb performance data.

The yaw rate or yaw velocity of a car, aircraft, projectile or other rigid body is the angular velocity of this rotation, or rate of change of the heading angle when the aircraft is horizontal. It is commonly measured in degrees per second or radians per second.
How to change the type of interest rate on a product. Often you won’t have a choice between fixed and variable rates — even if the product you need would benefit from one more than the other.
The rates of change of lift and drag with angle of attack (AoA) are called respectively the lift and drag coefficients C L and C D. The varying ratio of lift to drag with AoA is often plotted in terms of these coefficients. For any given value of lift, the AoA varies with speed. Graphs of C L and C D vs. speed are referred to as drag curves ...
A fixed-rate mortgage has the same interest rate for the life of the loan, so your monthly loan principal and interest payment won’t change unless you refinance. Fixed-rate mortgages typically ...
