Rescue hoist lift definition. A lift is defined as an unreeling and recovery of the
cable with a load attached to the hook, independently of the length of the cable that
is deployed / recovered. An unreeling / recovery of the cable with no load on the
hook is not considered to be a lift. Any operation where a load is attached for half the
operation (i.e. unreeling or recovery) must be considered as a lift.
When the helicopter operates in a sandy or dusty environment, multiply by two the
hours of operation with a load attached to the cargo hook. This applies also when the
helicopter is used for logging works.
