SF50 Takeoff and Landing Data helps Cirrus SF50 Vision pilots do their performance calculations. Simply launch the app, enter your weights, and the app will calculate how much runway you need to take off or land in your Vision Jet. SF50 TOLD supports both automatic and manual weather entry, custom safety factors, non-normal configurations (such as FLAPS 50 ICE or FLAPS 0), and runway contamination. All data comes from the SF50 G1 or G2+ Airplane Flight Manual* and is interpolated for current conditions. *This app has not been approved by the FAA or by Cirrus Aircraft as an official source of performance information. It is your responsibility to ensure that the performance data you use is accurate for current conditions.
