The main runway has the unique Vertical Take Off Grids (VTO Grids or Hover Grids) – used for the tethering of jump jets such as the Harrier whilst hovering. These are located on aprons that adjacent the main runway and are within the Operational Readiness Platform [ORP]. Beneath these gratings is a large void chamber to take the hot air, condensation and gases from the downdraft of the jet engines of the aircraft. Within the eastern Engine Testing Pen there is a similar arrangement that is a unique feature to Dunsfold.
