Piper are the same, if you look in the POH there will be graphs to determine Fuel time and Distance to climb or descend based on either VY or cruise climb speed (all the associated conditions will be defined on the graph itself). You usually go in with temperature and pressure altitude and it will spit out Gallons per hour, nautical air miles and time in minutes. You'll need to adjust the NAM for known wind if you want ground distance.
