Oh well, looks like no more flying for me for a while..
My usual mount is a shared C182, and the money to pay for the flying comes from profits (if any) made on investments. It's hard to justify the cost of private flying when the capital value of my investments has plummeted by around 40%.
At least, a very kind FTO where I did my IR offered me a relatively cheap rate to fly their FNPT-2 sim, so hopefully my expensively acquired ME/IR skills won't entirely fade away.
Anyone else in the same situation? Not looking for any sympathy, I should have seen this coming.
