Interesting comments from Smarthawke
I think that as Smarthawke's fleet is using the same tyres the lower use rate is probably due to a number of factors.
The airfield that his fleet fly from is considerably smaller than the airfield that my aircraft fly from this increses the amount of taxi time, we have no grass runway and some of the time Smarthawke's aircraft use the grass.
Unfortunatly smarthawke's airfield has a large number of NIMBY's that have forced a large circuit apon then making 5 landings per hour the norm, we have a very tight circuit making 14 landings per hour the average for circuit details.
I think that the large circuits forced on airfields are part of the reason that PPL students take so long to go solo these days, I don't think that the number of landings to solo has increased at all.
