Giuseppe Gasparini, head of transmission systems design and development at AgustaWestland, said when asked:
Q: What does the 30-minute run-dry requirement really mean?
A: I prefer to say “Loss of Lubrication,” or LoL, and not “run dry” or “run without oil”; we are demonstrating the capability of the gearbox to operate and transmit torque after the loss of most of its original lubricant when the oil is suddenly lost, but some residual lubricant is still inside the gearbox.
Like I said earlier, mate .... you go first
