VERTICAL CALCULATOR (VCALC) PROFILE

The VCALC page uses GPS position, GPS computed altitude, and pilot-selected 

parameters to calculate and display the time to begin descent and vertical speed 
required to reach a desired altitude above a designated waypoint offset.  The 
screenshot below is a sample profi le for an aircraft to be at 2500 feet MSL 4 
NM before KRNO.  Since the vertical speed is set to 400 feet per minute, the 
descent needs to begin in 4 minutes and 51 seconds. At the present location, a 
vertical speed rate of -21 feet per minute is required to reach the target. There 
are no menu options for the VCALC Profi le page.
