Definition

"an initiative ... developed to increase the lateral separation between aircraft with very accurate navigation systems on adjacent levels in case of altitude deviation errors. SLOP allows pilots to fly either the centreline, 1NM or 2NM to the right of centreline. SLOP may be applied from the Oceanic entry point, returning to centreline at the Oceanic exit point, by any aircraft with automatic offset programming capability".
