Hi Tim
You’ve doubtless realised that pilots are nothing if not opinionated! Some of the opinions are somewhat negative in my view but they’re valid for the person making them. I’ll come onto that in a moment. Regarding the Class 1 medical then absolutely need to get that before undertaking a course. That needs to be competed by an appropriately qualified AME. There’s no substitute for that and it isn’t cheap but even hobby flying requires a Class 2. I’m talking about the UK here although I’m sure the same will apply to every aviation authority.
After what has happened during the pandemic I would be very cautious about enrolling on an integrated course. I would suggest he gets the medical completed and all being well undertakes a PPL course first. If he shows the enthusiasm and aptitude then look at the modular route. I believe some of the schools in the UK offer dual UK/EASA courses. Unlike most UK students he presumably can work in France and possibly in the wider EU and of course he’s fluent in French I assume. If he can then by all means have another skill or qualification to fall back on.
Lastly, I would advise you and your son yes the airline industry can be brutal at times not least the last two years. However, after over 25 years in the business I haven’t ever regretted it and I left a secure job to start flying. I am unapologetically romantic about flying. For me I am not blind to the downsides, like nearly being made redundant twice, more that if he has a genuine passion to fly that helps to offset the negative aspects. It’s the best seat there is and if he ends up flying long haul there is the opportunity to travel to places he probably wouldn’t visit otherwise. Anyway, just my two penn’orth. Hope that helps.
