Hey everyone... just doing some reading... and wonder if anyone can help me out...

So in the CAO it talks about dropping of articles...and it’s not to be carried out within 5 miles of a government or licensed Aerodrome....
So are all aerodromes either licensed, or a government Aerodrome?
And then just classified as CERT, UNCR...

So even if the Aerodrome is PVT... you still couldn’t drop a flour bomb... because it’s only private, but to be in the ERSA it has to registered?

Also with RRM and IRM...it states that a Collision with a bird or animal is only RRM if it happens on a certified or registered Aerodrome.... so if it happens on a Uncertified... you don’t need to report it?
