And PIs - do you still have performance indicators?
We had 3 IIRC - economy, efficiency and something else. Our airship could then be presented with a set of number - decimal numbers below one AFAICR.
Now it came to pass in the December when the RAF was gearing up to its first war of the decade and simultaneously enjoyed a 3-week peace dividend holiday (go figure) that our efficiency score was low (big number?) as we had few flying hours and failed to reach our target flying rates. However our economy rating was superb. Our POL consumption figures were excellent, heating, lighting and water usage was similarly very low too.
Go figure.
