About This File
DescentCalc allows you to quickly calculate when you should start your descent when either assigned a crossing altitude or flying a STAR without the aid of ATC. Simply enter your current altitude as a flight level in the upper box, enter the assigned crossing altitude or the altitude indicated in the vertical planning section of the appropriate STAR chart in the lower box, and click "Calculate." The result is displayed in the box at the bottom. By Brian Wilber.
