Ah yes, I remember now, there was some system the fleet had which was recording information for a separate system, and I was looking at a way of hacking into it to get times for take-off and landing. The data we got mostly seemed to lie within the first week of the year 2000. This was the point at which we realised the engineers were taking the batteries out at weekends.
While we're at it, CAP371 contains the most arbitrary parameters; I mean, x days flying out of y days, q hours flown within t days, n days consecutive flying within j days, and don't get me started on the mandatory days off and the definition of standby. I remain convinced there are a very small number of simple algorithms that would vastly simplify the entire task and ensure pilots got enough rest (which would be a nice change for them, it sounds like). It's just designing those algorithms and then convincing the CAA.
Right! Who's up for that then?!?!
