Why is it that most manufacturers use a 3-letter/number code for labelling their range of products??
E.g. Bell 412, 407, 427, 429, 204, 214, etc....
Eurocopter 350, 355, 120, 130, 135, 145, 155, 365, etc...
MD 500, 520, 600, 900, 902, etc...
Schwiezer 269, 300, 333, etc...
Augusta 109, 119, 139, 169, etc...
Cessna, 152, 172, 182, 210, 401, 414, 510, 550 etc...
Boeing 707, 717, 727, 737, 747, 757, 777, etc...
Airbus 310, 320, 330, 380, etc...
Dornier 128, 228, 328 etc...
Socata 700, 750, 850, etc...
Air Tractor 301, 401, 501, 701, 801 etc...
Gulfstream 150, 200, 300, 500, 550 etc...
and many others! They must be about to run out of 3 number codes soon
Just an ironic and wondering thought?
