: 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
