Running a tank dry is no big deal, provided you’re at cruse power up at altitude and switch over to another tank reasonably quickly. I do this pretty regularly to make sure the gauge is still calibrated. Once it starts getting close to empty, I watch the fuel flow, and once it starts to fluctuate, I get ready to switch over.
I’m not sure what autopilot he’s got on that plane, but I know I don’t trust my old 800IFCS in my Twin Cessna on a coupled approach unless I’m watching it like a hawk. Even my lazy ass usually hand flies instead.
Hahaha... I love how NorCal approach asks him if his name is Jerry after he makes a turn in the opposite direction to "test airspeed" and they are wondering how long before he turns back on course. Around 5:55.
