Interesting thought, mad jock. It looks like if I do more than one hour per month, the PA28 shares work out cheaper than flying at the club. 5 hours a month in G-AVLB works out as £385 for the 5 hours, so averages £77 per hour. I'm going to have to find a good paying job if I want to be able to do that much flying while at school in the week!
Sadly, it does seem that for as long as I am stuck at Sixth Form, I shall not be able to earn enough to fly more than 2 or 3 hours a month, absolute tops. Unless I manage to create a business that earns me thousands while doing nothing, I shall have to wait until I finish and get a full time job. By that point, I'll be applying for cadetships and the like, so it seems that keeping my PPL current will be the main aim.
Best Regards
Luke
