12,500 in a 150.
It was ISA-30F all the way up. (-20F up at altitude)

FL550 at EDW in a T-38. We were doing training missions for NASA mission specialists. Took min-mid range AB to stay level at altitude, and didn't stay too long at that because of fuel.
Those DA20's will climb like a home sick angel if the conditions are right. Although, I've never took one that high before. What's the fpm when you get above 13k?GA: 14,000 MSL in a Diamond DA20-C1 that weighs less than 1800 pounds max gross!
121: FL370
FL499
Lear 40XR coming home from the west coast, requested a block altitude to FL510 and let her climb slowly while maintaining about Mach 0.80. We were just shy of FL500 when ATC started us back down. We had some information from the schoolhouse that suggested this profile was very efficient - max cruise power, maintain max forward speed, and take whatever climb performance the excess power provides. Interesting experiment, but we didn't see enough benefit to warrant going above FL430 in the future except to top the weather. I've been to FL470 a hand full of times for just that reason.
I'm not a big fan of being that high by the way.
Damn, that's pretty high. We routinely go to FL450 in the CJ3, it just sips fuel up there. 800 pph, 0.73 mach pretty much every time. It'll go straight there in about 26 mins in most conditions (fuel, ISA, etc.). During the climb, once through about FL380 it is so quiet with the thin air that pretty much the only thing you hear are the avionics fans. I snapped my avatar at FL450 on one of my first flights. It's amazing up there at night too...
