Sas,
Loss of t/r drive is a Land as soon as possible event. Not Land Immediately.
From my RFM (although for a B3):
3.3 Tail-rotor failures
3.3.1 Complete loss of tail rotor effectiveness
3.3.1.3 In Cruise flight:
1. Cyclic: Adjust to set IAS to Vy and control yaw
2. Collective: Reduce to avoid side-slip
Land as soon as possible
Approach and landing
On a suitable area for auto-rotative landing:
1. Twist-grip to IDLE detent
2.Carry out an auto-rotative landing as landing procedure.
Vy= 65kts at sea-level
It's been many years since I last flew a BA so I can't remember exactly, but I can't really think the procedure is much different as the main difference between the two is the engine.
