Register size
Register size across every register we track for aircraft.
What is meant by register size?
How many entries the register carries, as the registry itself reports it, with the date of the count.
Why does register size matter when choosing a register?
Size is a rough proxy for how experienced the registry, its surveyors and the banks and insurers who deal with it are, and for how familiar port and airport authorities are with the flag.
