when the slope magnitude in Figure E-1 is high, such as at This fact is very important since fuel consumption is the 10 mpg, there is a large change in FC for a small change in metric in corporate average fuel economy (CAFE) standards FE.

The calculation for average payload is as follows: For picking up cargo, the average payload equation would need a plus payload term for each segment to account for P1t1 + P2 t2 + … Px t x Average payload = = Pae the pickup. Therefore, P2 = P1 – Pd + Pp where Pd = payload t1 + t2 + …t x delivered and Pp = payload picked up after segment 1, where Px = payload in tons carried for time x when the vehicle is moving, and tx = time in hours carrying payload Px.
