An aircraft circling West along the Equatorial latitude for a year at the speed of the Earth's rotation would still experience a single day/night cycle even though it arrives back at the longitude of Quito after a 24,901 mile/ 40,075 km journey in 24 hours.

This corresponds to the orbital day/night cycle experienced at the North and South Poles each year where only one sunrise/sunset happens on the Equinoxes. This rotation turns the surface parallel to the orbital plane with a maximum rotational speed of 68 miles/per day.
