"Mike Rapoport" wrote in message ink.net... "John T Lowry" wrote in message ink.net... "Chris W" wrote in message news  462e.4423$Tn.2163@lakeread06...Can someone tell me if my thinking is correct here. First VLD is the speed where there is the least drag on the plane right? So it takes the least amount of power to maintain level flight at VLD, any slower or faster in level flight requires more power? Now suppose you are at an altitude where the fastest speed you can maintain is VLD, would that mean that the plane can't climb any higher? Also would that be a reasonable way to determine VLD, (i.e. climb as high as you can and the indicated airspeed at that altitude would be VLD)? -- Chris W Has anyone mentioned that you can't GET to maximum altitude with finite fuel and finite time? John Lowry Flight Physics Max altitude is reached with minimium fuel right before the engine quits. You certainly can't reach max altitude starting with zero or infinite fuel. Mike MU-2 Von Mises, p. 416: "It can be seen by simple reasoning that the ceiling altitude cannot be reached within a finite time." John Lowry Flight Physics
