=leftDirect costs means the costs directly incurred in relation to a flight (e.g. fuel, airfield charges, rental fee for an aircraft). There can be no element of profit.=leftAnnual costs which cannot be included in the cost sharing are the cost of keeping, maintaining, insuring and operating the aircraft over a period of one calendar year. There can be no element of profit.
That is a funny one and one that has been raised before.
Case 1 - I rent an aircraft from a club or owner and my 'cost share' can be calculated on that cost which does include the full hourly cost of the direct and indirect costs
Case 2. - I use my own aircraft so suddenly the hourly rate reduces from £200 to around £80-100 or so.
Of course, what I could do is to buy an aircraft, set up a company to operate it and rent it back to me at the higher rate. Does it matter if the hourly rate my own company charges me includes admin fees and other indirect costs that puts a £172 to £400 per hour, if the market will bear it?
