One word. Risk.
Risk to servicing your loan, risk to your house (if you have one) and risk to your loved ones sanity.
There are many "what if's" in aviation (and indeed life). Aviation, in particular Charter and holiday type Airlines are extremely sensitive to the economy. If the economy sneezes, aviation catches a cold. There has been no real sign that the economy of European nations and the US of A is out of the doldrums yet.
So lets say you start training now, 2 years on you are ready to enter the workforce as a pilot. Bear in mind, there are a lot of unemployed pilots out there RIGHT NOW. Many are only partially employed or on unpaid leave.... Now, lets us consider the economy doesn't pick up. The employment rate is still low and now you have a 50-60K+ loan to service. If the going's good you should still be able to work and wait. If the going's not good? Then what?
You are flat out staying current, let alone ready for a sim check.
If you are someone that is seriously cashed up and don't have to pay off a loan or mortgage then you are ok. If you need to get a loan etc, think twice about it.
By all means, start the relatively cheap options like doing a PPL and the like. However, stop and reassess every move. Watch the economy like a hawk and not with rose coloured glasses.
Think of this flying game like buying a house. You wouldn't spend 50,000 pounds without having an engineer survey it and a solicitor go through the deeds etc? Look at aviation with the same objectivity.
Aviation isn't strictly a sine wave, more like a delayed saw tooth.
After the last bunfight in the Gulf, (1991) it took till about 95-96 for some recruiting to occur. Then it boomed in 97-99.
Cold hard facts. Ignore them at your peril.
