Thank you guys for your inputs.
awair, I'l make sure to PM you. I only had SEP land.
Arrow Flyer: His licence says "Multi-pilot operations only" just under ICAO English level and then again next to A320/IR/LVO/PBN in section XII. We both have same backgrounds and training, I was just lucky enough to meet ATPL requirements couplne months earlier.
I understand now that most probably my ATPL licence without this multi pilot restriction is correct. Let me rewrite my original question then. Can I do aerial works in a Cessna and be paid for that just like if I had CPL?
