What are the flap settings during takeoff for the Falcon 7X?

The flap settings during takeoff for the Falcon 7X are indeed SF1 or SF2. Using these flap settings optimizes the aircraft's lift characteristics during the critical phase of takeoff, enabling a safe and efficient climb. SF1 offers a moderate increase in lift and drag, which is beneficial for a gradual takeoff, while SF2 provides additional lift which can reduce the required takeoff distance, particularly in demanding conditions such as high elevation or hot temperatures.

Other settings like SF0 would not provide sufficient lift during takeoff, which could compromise the aircraft’s performance. Likewise, SF3 would typically be used for landing rather than takeoff, as it increases drag more significantly than lift relative to the other settings, leading to unnecessary performance limitations when the aircraft is trying to gain altitude. Thus, SF1 and SF2 are the recommended options that strike the right balance for safe takeoff performance.
