This revision of the British Standard has been prepared under the direction of the Aerospace Standards Committee and superscd,s British Standard G 199: 1967, which is withdrawn. Terminology has been rationalized to align with accepted international practice. New formulae have

The altitude. tables and altitude parameterswhere used in other tables are based on the now universally accepted ICAO Standard Atmosphere, 1964:which is identical to ISO 2533 over the tabulated altitude range. The airspeed tables and those where airspeed

9、 is a parameter are calculated from the de St. Venant and Rayleigh formulae, the values of the base constants being those of ICAO Document 7488/2, ISO 2533 and BS 350. The tables are primarily for use in the aircraft instrument field and do not provide for other special interests, e.g. aerodynamics

10、or space technology. The information is therefore not comprehensive and ranges are confined to probable aircraft reqldrements in the foreseeable future.

12、use in aeronautical instrument design and calibration. The size of the tables have been restricted and the units used for the various parameters have been kept to a minimum. namely, altitude in geopotential feet, pressures in millibars and inches of mercury, airspeed in knots, and temperature in deg

13、roes Celsius. NOTE. Altitude measurements are based on the geopotential foot. and, in speed measurements where the knot is involved. this is t3ken to mean one international nautical mile per hour. 2 Basis oftables 2.1 Notation and standard values Altitude Igeopotential) H Free stream static pressure
