From my limited experience to date, knowledge of a hypothetical flight profile in that level detail is worthless. The atmosphere is volatile and dynamic. In many aerospace applications we assume a static atmosphere and for that matter a flat Earth. What is more crucial is building the flight control system. It's not really practical to just pull out a FCS from one aircraft and plug it into another. For the code warriors out there, this is probably the among the more daunting tasks that lie ahead of you. . Something that ERPS most certainly requires for when things go weird, wild, and wacky is this FCS and associative avionics package. . Making the vehicle fly is one thing, making sure it flies under the weird and wacky conditions is completely different. That may be a worthwhile simulation (how the aircraft reacts to various control inputs in various situations). But simulation is not very valuable until you flight test the hardware anyways... it's all in how you build it not necessarily how you design it. When I complete my analytical solution for suborbital re-entry, I'll begin to participate more in the area of flight mechanics. I plan to publish a few papers to the AIAA Student Regional Conference this spring on this topic. Who's in charge of the flight mechanics area? - Justin S.
