Going back to the original thread, first thing to do is to write down every expense you can think of, for example
aircraft loan repayment ( buy over 5 years, your students would have bought you a nice aeroplane to retire on!), maintenance (50hr and annual, C of a), engine fund ( remember if busy 1000hr per a/c/yr, engine will be burnt out after 2 yrs), insurance(last time think it was 4% value a/c, plus £100 per seat), rent, rates, parking, block landings, fuel, wages with tax!( your self and office staff ), 3rd party liability insurance, advertising, office equipment. don't forget VAT!
Now have to decide how many aircraft, 1, 2 or 3.
Don't believe anybody could afford to buy anything fancy, stick with basic Cessna/Pipers. easy to fix if pranged.
How many hours do you think you are going to do per year?
Would 2 a/c 1000hr year make a profit?
Income from groundschool, charge for it, they do in USA, so why don't we do it here. I was always embarrased to, because of the already high cost of flying. Who looses out?
Ground exams, r/t courses, flight test if examiner.
what ifs?
Engine blows up, a/c damage off line, more bad weather, price of fuel goes through roof.
Like any flight it requires careful pre flight planning, the results are not only monetary, but thats what keeps the dream airborne.
