Why are Germans always trying to cheat on economics, what's it called now "Geiz ist Geil"?
You cannot defeat economics truth on long term! A decent aircraft for training in Germany will come at about 200 Euro per flight hour (beware of their bloody CAA fighting all flying) and they have a minimum wage of 8.84 Euro per labor hour. Given the German vulture factor between turnover and wage of 4.2 this comes to a fee of 37 Euro per hour for the instructor at minimum wage (only if you are brash ignoring the human economic life of your instructor), or 237 Euro for an hour of flight on FI supervision. At 45 hours flight training according to EASA syllabus you always end at 10.665 Euro - pure flying. Plus theory, plus material, plus radio license & LP & etceteras you have to expect 15.000 Euro.
If you don't have 15.000 Euro to spend for the license, you most probably will never be able to afford keeping your license. If you aim to become an experienced pilot, you probably need about 100 hours of flight per year to stay so - another 20.000 Euro per year to spend.
So, what is the amount of money thought to save with a "cheap" PPL? Being a noble airmen very seldom plays in the 4-digit Euro per year regime, so why bother taking the risk of spending money on "cheap" education"? Whatever you may be able to save on the license is peanuts compared to the money you will spend being an airmen.
