Beechcraft King Air 350i Startup Notes
The 350i is a lesson in PT6 discipline. Everything runs through the condition levers: they sit at fuel cutoff for the start, and the moment you lift one to low idle you are committed to fuel and ignition. Engage the starter, wait for N1 to spin up and stabilize, at 12 percent minimum, then bring the condition lever up while watching ITT climb. The second engine is normally a generator-assisted cross start, and the autofeather system gets its own dedicated test at runup.
Hot starts are the big trap. Lifting the condition lever before N1 stabilizes means fuel pooling in a slow-turning engine and an ITT that rockets toward the limit; if it runs away, cut the fuel and keep motoring. Impatience causes the second classic error: cross-starting engine two before the first generator's load has dropped enough to support it. And plenty of sim pilots skip the autofeather test entirely, which on this airplane is a real checklist item, not decoration.
Common mistakes
- Raising the condition lever before N1 stabilizes at 12 percent
- Cross-starting the second engine before generator load drops
- Skipping the autofeather test at runup
