Country prefixes - the situation today:
1) Many different formats exist, e.g. D-ABYY, N169DZ, HP-1525CMP, etc.
2) Country prefixes do not logically represent their countries (EC = Ecuador? - Spain; N=USA=why? TF=Iceland=why? and so on.)
Wouldn't a standardization to ISO country codes, followed by four letters, solve a whole lot of confusion?
For example, a plane that was formerly registered D-ABVA would become DE-ABVA. No big deal.
All US planes would be US-XXXX, where they could do the first two letters according to the airline (US-AAXX for an AA plane), which would give them 676 slots before they need a second one)
Ireland planes would become like IE-ALAX for example. (taking EI-LAX as an example).
UK planes would be like GB-BDXG where it was G-BDXD before.
What do you think about this?
