These formulae were obtained by fitting curves to the data given ...
Speed of sound as a function of altitude. Refers to a Mach number, or the ratio of the speed of an airplane to the speed of sound in the same atmospheric conditions. It is also used as a speed unit. The speed of sound, or Mach 1, is equal to 340.5 m/s, 661 knots, 761 miles...
As the Mach number is defined as the ratio of two speeds, it is a dimensionless quantity. If M < 0.2–0.3 and the flow is quasi-steady and isothermal, compressibility effects will be small and simplified incompressible flow equations can be used.[1][2] 【参考译文】本地声速和因此马赫数...
The Mach number M is defined as the ratio of the true airspeed V to the speed of sound a in air at the flight altitude: (15)M=V/a For the calibration of Machmeters, the Mach number can be related to the ratio of the impact pressure to the static pressure qc/P by the following ...
As the rays propagate from the airplane to the ground, the speed of propagation (VP) changes mostly as a function of atmospheric temperature changes. Generally, this change in temperature results in an increase of VP as the rays approach the ground. At the altitude of complete refraction, ...
This paper presents a method for robust flutter computation which uses flight altitude as the perturbation variable in order to obtain a match point solution. The air density and sound speed of standard atmosphere model are approximated as the polynomial function of altitude, such that the flight ...

TAFs and MOS4weather reports — alongside custom weather alerts as well as non-weather alerts like time, distance, altitude and a fuel timer. Utilize the wrist-based Pulse Ox sensor5to monitor blood oxygen levels and barometric altimeter for altitude alerts. And in case of an engine-related ...
This F-22A model has high-detail modelling and textures as well as complex customised flight control and instrumentation coding that may not function correctly without sufficient computing resources. We highly recommend minimum system specifications that meet or exceed the following: ...
The output signal is employed to control a synchro 174 by way of a motor 162, so as to furnish on leads 186-194 signals to control a computer. In accordance with the invention the signal is first linearized so that the output is a linear function of Mach number. In a first arrangement...
