Hmmm. What are you saying here Scott. If you're talking about high altitude flying without O2, I certainly agree with you. But are you against flying above 10 WITH oxygen? I've had mine up to FL210 (with oxygen, of course) with no ill effects.
Bill, et al:
Every airplane is designed around some parameters where its cruise performance is optimal. Wing/tail incidence calculated against IAS at certain pressure altitude and aircraft weight, CG, temperature, etc...... You can fly it higher or lower, faster or slower, lighter or heavier but, the "best" performance for an LNC2 occurs at about 1685 lbs, mid range CG, about 9000 ft pressure altitude, 225 mph TAS.
Note, however, that the Legacy was designed for a higher altitude, 12000 ft I think.
There are other items that affect a successful and quick flight. 9000 ft doesn't get you over every mountain, into a 50 Kt tailwind, or out of all turbulence. I just find my cross country performance has been best at 7500, 8000, 8500 and 9000 ft altitudes, all other things being equal.
