  2. Drag curve - Wikipedia

    The corresponding maximum range condition is the maximum of C L 3/2 /C D, at C L 2 = 3.C D0 /K, and so the optimum speed is 244 km/h (152 mph). The effects of the approximation C L0 = 0 are less than 5%; of course, with a finite C L0 = 0.1, the analytic and graphical methods give the same results.

  3. Speed to fly - Wikipedia

    en.wikipedia.org/wiki/Speed_to_fly

    The speed to fly is the optimum speed through sinking or rising air mass to achieve either the furthest glide, or fastest average cross-country speed. [1] Most speed to fly setups use units of either airspeed in kilometers per hour (km/h) and climb rate in meters per second (m/s), or airspeed in knots (kn) and climb rate in feet per minute (ft ...

  4. Speed and rate of climb - Wikipedia

    en.wikipedia.org/wiki/Rate_of_climb

    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).

  5. Lift-to-drag ratio - Wikipedia

    en.wikipedia.org/wiki/Lift-to-drag_ratio

    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. Speed is shown increasing from left to right. The lift/drag ratio is given by the slope from the origin to some point on the curve and so the maximum L/D ratio does not occur at the point of least drag coefficient, the ...

    (For example, a pitcher's fastball speed might be 1–2 mph faster at home than on the road.) [6] PITCHf/x uses algorithms to automatically classify every pitch by type, but these algorithms are imprecise. [7] For the 2017 season, PITCHf/x was deprecated and replaced by TrackMan, a component of Major League Baseball's Statcast platform. [8] [9]

  7. Flight envelope - Wikipedia

    en.wikipedia.org/wiki/Flight_envelope

    For instance a Cessna 150 at 2,500-foot (760 m) altitude and 90-mile-per-hour (140 km/h) speed needs about 60 horsepower (45 kW) to fly straight and level. The C150 is normally equipped with a 100-horsepower (75 kW) engine, so in this particular case the plane has 40 horsepower (30 kW) of extra power.

    This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
