What does VY mean in aviation? best rate-of-climb airspeed. Failure to attain/maintain best rate-of-climb airspeed (VY) or desired climb airspeed. ? Failure to employ the principles of attitude flying during climb-out, resulting in ?chasing? the airspeed indicator. Crosswind Takeoff. For 2D motion, the velocity vector v can be represented as: v = (vx)i + (vy)j, where vx is the horizontal component and vy is the vertical component of velocity. What formula is Q MC ∆ T? The formula Q = m × c × ΔT represents the heat transfer (Q) involving mass (m), specific heat capacity (c), and temperature change (ΔT). On a normal takeoff, we typically pitch for the speed that gives us our best rate of climb, known as Vy. What causes our best rate to be found at this speed, Behind Vy we are in the region of reverse reverse command, where it is taking us more power to decrease our airspeed and maintain altitude. Vx is slower than Vy (and if you draw an ordinal tangent to the airspeed vs vsi curve, the point where it intersects the curve is Vx), and so you are needing more power to maintain an altitude at a Vx than Vy. The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant. The slope of a velocity graph will be given by the following formula: slope = rise run = v 2 − v 1 t 2 − t 1 = Δ v Δ t. v ( m / s) t ( s) r i s e r u n t 1 t 2 The largest space between the two lines happens left of the lowest point of the curve. This is so because of the slope of the thrust available line. Meaning, we have the most excess force (thrust) at a slightly lower airspeed than our minimum drag speed (Vmd). THAT IS OUR VX! Vy. Vy is your best rate of climb speed. Wing planform and aspect ratio probably have different effects on Vs and Vx/Vy as well. And different airfoils with different lift/drag curves are likely to have different relationships between Vso and Vy or Vx regardless of the thrust issue. Finally, Vso brings another variable to the equation in that the difference between Vso and Vs is Node voltage "ei" is the upper left corner, between the two resistors. The bottom edge of the circuit is ground. Finding voltage ei is actually very easy. The current everywhere in the loop is 1A. The 1ohm resistor is connected between ei and ground. It has 1A flowing through it. Therefore the voltage at ei is 1V. .
