I do not use it in my current position, but I am a form 4 holder. I was also a Camo, LAME, C Cert’er, form 4 holder, all rolled into one.
Basically I did it all, I even had to write the Company Exposition and the Maintenance schedules lol.
So I wrote the maintainable programme, carried out that programme, certified and cleared that programme, had camo oversight on that work and issued the Arc renewal.
