1. A method for a ramp system configured for use between a jetway and an internal cabin of an aircraft, the ramp system comprising:
a first panel;
a second panel; and
a pivot axle that pivotally couples the first panel to the second panel, wherein the first panel and the second panel are configured to rotate relative to one another about the pivot axle between a closed position, in which the ramp system is stowable within the internal cabin, and an open position, in which the ramp system is deployable over and between a first portion of the jetway and a second portion of a floor of the internal cabin,
the method comprising:
moving the ramp system into the closed position by rotating the first panel relative to the second panel in a first rotational direction about the pivot axle;
stowing the ramp system in the closed position within the internal cabin;
moving the ramp system into the open position by rotating the first panel relative to the second panel in a second rotational direction about the pivot axle, wherein the second rotational direction is opposite from the first rotational direction; and
deploying the ramp system in the open position over and between the first portion of the jetway and the second portion of a floor of the internal cabin.
