The invention discloses an aviation cockpit double-dimming curve synchronous control system and method. The control system comprises a control unit, an adjustable voltage source unit, an electronic switch unit and a light-emitting load unit. The control unit is configured to provide a voltage dimming signal and a PWM dimming signal to the adjustable voltage source unit and the electronic switch unit, the voltage of the voltage dimming signal provided in a first external light environment is constant, and the duty ratio of the PWM dimming signal is variable based on a PWM dimming curve. The voltage of the voltage dimming signal is variable based on a voltage dimming curve and the duty cycle of the PWM dimming signal is constant in a second external light environment. The method has the beneficial effects that through the double-curve synchronous control of the voltage dimming curve and the PWM dimming curve, the large-range and wide-dynamic coordination and uniform dimming of the light-emitting load unit are realized, and the requirements of wide-range and low-level brightness adjustment of the current aviation night flight are met.
