Not entirely convinced by this but I suppose we need to see it in action before we can pass judgement on it. Concerns would be a loss of Sqn level control over how personnel are allocated (there's a lot more to planning than who is actually available and current), a possible loss of flexibility but more importantly an increase in the amount of meddling from exterior agencies in sqn level planning matters. There is a risk that some ops planner at DTMA, Gp or wherever will see that there are personnel "available" and be on to the sqns demanding an explanation as to why so-and-so can't be allocated to a trip.
Like I said, it may be the great panacea to solve all our woes but the final decisions must rest with the sqns and off-station planners mustn't use it as a way of forcing sqn level decisions.
To be fair though, we can churn out as many planning programs as we like and tip as much money as we can into new IT systems but if we ain't got the serviceable aircraft then we might as well go back to perspex boards and chinagraphs pencils..
