속도의 종류(IAS/CAS/EAS/TAS/GS, 지시/수정/등가대기/진대기/대지)

근거 : FAA PHAK 8-8, 조종사표준교재 비행이론 2-100 Just as in altitudes, there are multiple types of airspeeds. Pilots need to be very familiar with each type. • Indicated airspeed (IAS)—the direct instrument reading obtained from the ASI, uncorrected for variations in atmospheric density, installation error, or instrument error. Manufacturers use this airspeed as the basis for determining aircraft performance. Takeoff, landing, and stall speeds listed in the AFM/POH are IAS and do not normally vary with altitude or temperature. • Calibrated airspeed (CAS)—IAS corrected for installation er..........
