1. Elevation and Height References 근거 : Jeppesen ICM 7-9 1.

Airport/Field Elevation(MSL) Highest point of an airport's usable runways measured in feet from mean sea level. 2. TDZE(MSL, Touchdown zone Elevation) : Highest elevation in the first 3000 feet of the runway landing surface. 3.

TCH (AGL, Threshold Crossing Height) : AGL height at which you cross the threshold if you continue the approach to a landing while maintaining the glide slope/path or vertical descent angle. * 참고 : The published glide slope threshold crossing height (TCH) DOES NOT represent the height of the actual gli..........
