The International Civil Aviation Organization (ICAO) published their "ICAO Standard Atmosphere" as Doc 7488-CD in 1993. It has the same model as the ISA, but extends the altitude coverage to 80 kilometers (262,500 feet). [7] The ICAO Standard Atmosphere, like the ISA, does not contain water vapor. Some of the values defined by ICAO are:
Type MTOW [kg] MLW [tonnes] TOR [m] LR [m] ICAO category FAA category; Antonov An-225: 640,000: 591.7: 3,500: Super: Super Scaled Composites Model 351 Stratolaunch
G500 at EBACE 2018 Gulfstream GVII-G500 interior. The G500 was taxiing under its own power at its unveiling on October 14, 2014, [13] and it first flew on May 18, 2015. [1] The model was initially planned to be certified in 2017.
corporate interior. The Challenger 850 is derived from the Bombardier CRJ200 airliner. It is capable of accommodating 12–16 passengers. The Challenger 850 jet has a transcontinental range and a high-speed cruise of Mach 0.80.
The mathematical formulas that equate to the results of the flight computer wind calculator are as follows: (desired course is d, ground speed is V g, heading is a, true airspeed is V a, wind direction is w, wind speed is V w. d, a and w are angles. V g, V a and V w are consistent units of speed. is approximated as 355/113 or 22/7)
A straight line from the origin to some point on the curve has a gradient equal to the glide angle at that speed, so the corresponding tangent shows the best glide angle tan −1 (C D /C L) min ≃ 3.3°. This is not the lowest rate of sink but provides the greatest range, requiring a speed of 240 km/h (149 mph); the minimum sink rate of about ...
The relative air mass is only a function of the sun's zenith angle, and therefore does not change with local elevation. Conversely, the absolute air mass, equal to the relative air mass multiplied by the local atmospheric pressure and divided by the standard (sea-level) pressure, decreases with elevation above sea level.
Angle of loll is the state of a ship that is unstable when upright (i.e. has a negative metacentric height) and therefore takes on an angle of heel to either port or starboard. When a vessel has negative metacentric height (GM) i.e. , is in unstable equilibrium, any external force applied to the vessel will cause it to start heeling.
