There are 4 sites at Brands used by Helicopters:
2 in the NE of the site, by the bungalow, at 51-21 -51.43N, 0-15-34.32E and 51-21-45.54N, 0-15-34.11E
The post JP uses and the Medevac at 51-21-26.62N, 0-15-55.25
Finally the Heliport used for larger events at 51-21-56.01, 0-15-55.25E and has a 06/24 aligned runway. This is usually managed by Gaeko whose details are in the BHAB handbook.
Hope this helps
