5.1 Cranes can adversely distract pilots' attention
during helicopter approach and take-off from the helicopter landing
area as well as infringe fixed obstacle protected surfaces. Therefore
it is essential that when helicopter movements take place (±5
mins) crane work ceases and jibs, etc. are positioned clear of the
obstacle protected surfaces and flight paths.
5.2 The Officer(s) in charge of helicopter landing
area operations team(s) should be responsible for the control of cranes
in preparation for and during helicopter operations.
