From the project

555 IC Circuit of Airplane PCB with Astable Dual LED Flashing ✈️✨

The duty cycle of a circuit is ratio of the time the signal is active (high) to the total period of the signal. We want the duty cycle of this circuit to be close to 50% in order to get a congruent off/on blinking pattern form the airplane LEDs.

R1:R2 ratio predominately is what sets the duty cycle for the circuit
