Dorosenco.....
Your comment about hours building is not entirely true...For clarification, Aircraft used for the greater part of hours building must be of the correct weight, ie., a group A aircraft; it is not sufficient to fly all of the hours on say a Microlight, or ULA. Up to 500 of the required hours, may, however, be completed in a Self Launching Motor Glider and up to 100 hours on microlight Aeroplanes may be included in the hours requirements too. This is based on the hours requirment for the CPL(A). I offer this in an "unqualified" manner, as I am going by memory. I suggest that for total accuracy - and minimum disappointment, that the correct information is sourced from the CAA, either by checking the appropriate section of LASORS 2003, and/or visiting the CAA Website.
Hope that helps.
