You will get all the minted up types here with, "I only fly the Bonanza a hundred or two hours a year" or, " I managed at least to keep current in the tatty c150 at my local field." from the less well heeled.
Sadly very true. It all depends on how deep your pockets are. I reckon the 'average' private pilot, assuming they only fly for leisure (i.e no hour building or require to progress onto different ratings etc) probably does in the region on 15-40 hours per year. However, you may invest in a share, allowing reduced cost flying and so do 100+ hours pa. All dependant on £££ unfortunately. One of the rare hobbies that requires a heavy wallet to do a lot of. I'm always asking myself: 'Why can't I just enjoy racing RC cars, or collecting stamps? I'd have so much more spare cash'
