of the standard atmosphere, all air

of the standard atmosphere, all aircraft performance instrumentation is calibrated for the standard atmosphere.
Because the actual operating conditions rarely, if ever, fit the standard atmosphere, certain corrections must apply to the instrumentation and aircraft performance. For instance, at 10,000 ISA predicts that the air pressure should be 19.92" Hg (29.92" - 10" Hg = 19.92") and the outside temperature at -5°C (15° C - 20° C). If the temperature or the pressure is different
than the International Standard Atmosphere (ISA) prediction an adjustment must be made to performance predictions and various instrument indications.

atmosfer standar, Semua pesawat kinerja instrumentasi dikalibrasi untuk suasana standar.Karena kondisi operasi yang sebenarnya jarang, jika pernah, cocok suasana standar, koreksi tertentu harus menerapkan kinerja instrumentasi dan pesawat. Misalnya, di 10.000 ISA memprediksi bahwa tekanan udara harus 19.92" Hg (29.92" - 10" Hg = 19.92") dan suhu luar di 5 ° C (15 ° C - 20 ° C). Jika suhu atau tekanan yang berbedadaripada prediksi suasana standar internasional (ISA) penyesuaian harus dilakukan untuk kinerja prediksi dan berbagai instrumen indikasi.
