 * **Parallel runways** and **multiple parallel runways** are characterised by runways which are parallel to each other. If an airport has two parallel runways, it is called a parallel runway system. However, if more than two runways are parallel, it is called a multiple parallel runway system. For the operation of parallel runways, two geometric properties illustrated in figure @fig-distances-parallel-runway are important, namely (i) the separation distance between two parallel runways and (ii) the stagger between parallel runways. The separation distance describes how far apart the centrelines are between two parallel runways, while the stagger distance describes how far apart the thresholds of the parallel runways are in the direction of the longitudinal runway axis.

-First, let us look at how the separation distance affects the operation of parallel instrument runways, which are runways that allow for operations under instrument flight conditions. According to CS ADR-DSN.B.055, the minimum separation distances between parallel runways defined in table @tbl-parallel-rwy-distance must be maintained so that the modes of operation illustrated in figure @fig-mode-operation-parallel-runway can be performed.
