If you can depreciate the cost of an aeroplane over say 10 years, surely you can do the same thing with the qualification that you intend to use over x number of years...
I like your thinking - but the cost of flying training is an
expense and deductible for tax purposes only in the year it is incurred. Also, it is only deductible if you earn income from flying or it is essential to gaining your income.
An aeroplane is an
asset and may be depreciated over the life of the asset but only if it is essential to achieve your income.
Understand the difference between an expense and an asset. An expense is a wife/girl friend, drinking habit or a vacation in Bali. An asset is bricks and mortar, something you park in your garage, or an aircraft if it contributes to your income. (To confuse you, if the aeroplane does not contribute to your income, it becomes an expense!)
