2-man rule for the single pilot Wasp was upheld by the Helicopter Controller (HC) in either a surface ship or a dipping helicopter (Wessex 3 or Sea King) running through lengthy challenge/response checks between controller and attacker, whilst also directing the Wasp to the correct release position. Quite a busy time and practised ad nauseum in the simulator! Appropriate Stand-Off Ranges were calculated taking into account windspeed and direction, and escape instructions were given to the dropping a/c (which could also have been another Sea King or Wessex) to try and give it a survival chance...
