I wonder how the plumbing of the ferry tank in the pressurised cabin is designed to reach the fuel system, feeding into one of the wing tanks? Presumably there is a reasonable engineering solution, but if it is due to fuel exhaustion typically you would test the ferry tank before the PNR using the normal fuel system.
Wow, happy to hear both crew survived!
A PC12 on a ferry flight was forced to ditch about 1100 NM east of Hilo on a ferry flight from Santa Maria (KSMX) to Hilo.
Will be interesting to hear what caused this.
