Love that plane! Fly very fast, 6 folks and low fuel consumption. And unlike what our American friends state, FL does exist below 180...in Belgium depending on the transition layer (which depends on the current QNH vs 1013 or 29.92), it is most of the time close to FL050 so way below 180. Just open your mind guys and be curious!
Back in the day, My Company had a Turbo 210 , East bound from Denver with a slight tail wind at 17K my DME readout was 236 MPH GS that was in 1976....Too bad it was Pressurized.
James Segrest, this plane is flying inside Brazilian airspace, under Brazilian registration and Brazilian rules, and here, since you are using 1013hpa/29.92 on altimeter, you are flying in a Flight Level. The ACC doesn't inform us about QNH during the flight, only during take off or descent. Thats why the plane is flying in the FL125, and not 12.500.
I notice in Europe altitudes are referred as Flight Levels, but their Air Traffic system is somewhat confusing and overly detailed with clearances, offering different types of "Services".
