On rego numbers in RAAus
9,999 in each sequence
10- will never hit the limit as very few go there any more
25- are a closer favtory group so no issue
28- as old 101-28 homeguilt saaa aircraft will never hit their limit
32- trikes will never hit their limit - the hgfa trikes have T not 32 leading so no practical reason duplication can’t occur
now we have 18- 19- 23- etc all with 9,999 options.
I dont see that that RAAus really needs to recycle numbers any time soon because there are large gaps in sequences when over the years they have done odd sequence blocking’s.
moving to VH-1234 would actually substantially reduce the total available and don’t forget we have to label them 6” high with proper gaps so racking on extra digits is problematic.
