vm2 is absolutely correct. Three slots a day each (at best) which makes for 1.5 hrs per day, 7.5 hrs per week or 30 ish hrs per month. Given that weather, serviceability, visits, other commitments will all eat in to this figure, there is either some inaccurate reporting or wilful misinterpretation. IIRC each jet flies approx 250 hrs per year.
Presumably, someone else will now jump in and point out that this is actally poor use of the aircraft!
