※ 引述《hisemail (星巴克一年級生)》之銘言： : 請問飛機的速度計算方法~~在空中的速度跟地面上 : 計算都是一樣的嗎? : 跟地球旋轉的方向有影響嗎? 飛機在空中用的都是TAS,是由 IAS->CAS->EAS->TAS一步步修正來的 IAS (Indicated airspeed) Definition: Airspeed indicated by the airspeed instrument. The indicated airspeed is affected by altitude, compressibility, instrument, and position errors. CAS (Calibrated airspeed) Definition: Indicated airspeed corrected for instrument and position errors. EAS (Equivalent airspeed) Definition: Calibrated airspeed corrected for compressibility. TAS (True airspeed) Definition: Equvivalent airspeed corrected for density. 要知道Ground Speed還挺麻煩的 需要有True airspeed,True course,Wind velocity,Wind direction 之後就可求得True Heading跟Ground Speed了 要算Ground Speed的話可以用Flight Computer http://en.wikipedia.org/wiki/E6B Flight Computer還滿好玩的,可以算很多東西 Ex:飛行時間,距離,數據,油耗等等....... 我自己有一套,是由JEPPESEN出的 --
