From our ops manual:
2.1.22 Use of Automation
While pilots should make full use of the highest level of automation available to reduce workload, this must be balanced with the need to maintain manual handling proficiency. At all times the level of automation being used must be appropriate to the task.
At any stage where the aircraft response is not appropriate or adequate, the
automation must be disconnected with the subsequent reversion to manual flight.
When conditions and workload allow, pilots may elect to hand fly. This must be briefed as part of the departure or arrival briefing and remains at the discretion of the Commander.
