Calibration

Calibration is what makes OnSpeed work for your specific aircraft. Without calibration, the system doesn't know the relationship between its sensor readings and your aircraft's actual angle of attack.

What Calibration Does

The calibration wizard has you fly a controlled deceleration from cruise to near-stall. During this sweep, the system records pressure and attitude data, then fits a mathematical curve that maps sensor readings to AOA. It also extracts the key aerodynamic parameters:

  • alpha_0 — the zero-lift angle of attack (the AOA baseline)
  • alpha_stall — the stall angle of attack
  • AOA setpoints — the specific AOA values where tone transitions happen

Each flap setting needs separate calibration because extending flaps changes the wing's lift characteristics.
