Really taken back by the amount of replies & advice here, you are all clearly very knowable & have that ''thing'' you cant buy ..... Experience!!
He is doing his PPL at the moment & has flown around 20 hours so far, its a local flying club down the road from us @ EGC Bergerac Dordogne Périgord Airport. Fantastic place & very fair with pricing but there is a limit to what we can offer him & to be honest putting our family home up to secure the funding or debt is NOT something we would do.
He would only have to fail a medical by the sounds of it and thats that - no job ! plus we would lose our home. In my option its also not fair to let a young adult sign up to / agree that his family home is being used as collateral.
We tell our kids to aim high, try hard & then try harder lol the world is tough & as its been pointed out its also changing very fast - Once again thank you for the feedback & advice. So helpful & lots i didn't even think of.
