Keeping licenses valid post integrated route
Hi all, I plan to start integrated training in early 2022, the structure and continuity appeals to me and as I have recently finished university and don't have a specific job or any commitments to hold along side a part time modular course I would rather just get stuck in and spend 18 months getting everything done and obtaining my license and take it from there. I am aware most people are recommending modular at the moment for obvious resons, but if I were to go for intergrated and graduate say late 2023 and there was still no airline jobs, what are the processes for keeping licenses valid? I would probably look to work at a simulator company or become a flight instructor until there are airline jobs, does this automatically keep licenses ticking over?
No need to tell me, wait 2 years, spend this time getting a degree (already done that), there wont be any jobs for another 5 years, integrated is a waste of money etc. Just want to know what the processes are for keeping licenses and ratings valid until I obtain my first airline job.
Many thanks in advance.
