Perhaps I'm confused (happens a fair bit to be honest) but am I the only one thinking that one number and two letters will give you even less callsigns than three letters, there being 26 letters in the alphabet and only 8 available digits (not counting 1 or 0 as mentioned above)?
Ahhh... disregard, I see now that they can come in any order, so there's heaps more permutations - or is that combinations? |
My mathematics are thus
Original format allowed for 26x26x26 = 17576 The new format allows for 26*26*8*3 = 16224 The total number of VH combinations is then 33800 |
Do we really have numbers of aircraft on the Oz register approaching 17,576??
I'm aware of the need to avoid immediate4 reissue of rego marks handed in but really??? |
Seems there are quite a few drones that have picked up VH- regos of late. Why can’t they be in a block of their own and leave some traditional rego’s to more conventional aircraft? After all, the gliders had a lot in the G block for many years. Drones could be VH-D2A etc.... I’m sure there would be others?

I'd do something like this

Not hard to find current numbers. 16040 registered currently 33 marks available. See CASA website

Why on Earth are drones given VH registration?
Seems a return to some understanding of basic principles might help. VH and other country prefixes, and their corresponding registries, exist primarily to show evidence of nationality of aircraft flying internationally. Since when do ‘Australian’ drones fly internationally? |

. Given they aren't mandating everyone change from the current VH-AAA to VH-AAA/N, rather they are adding an extra 8 possible figures in one column, I think it should be calculated as 26*26*34 - as it doesn't matter where the numeral is inserted, the *34 can be used anywhere in the formula.

As for why they need registration in the first place well I suppose that is CASA's decision to make. I can see an argument for it as it helps to identify drones that are ostensibly operated by people who should know the rules about where they should be flown. I don't believe they are given a VH registration though? |
I see. So you think that an Australian citizen who happens to be in the USA and buys a drone to fly while in the USA will be applying for and granted VH registration for that drone by CASA?
As to your second point, there are many aircraft flying around in Australia without VH registration. Have you heard of RAAus, for example? CASA seems to think there’s no ‘regulatory risk’ in those aircraft not being on the VH register. |

So apparently there are well less than 100 GA rego combinations left, reducing at a rate of over 10 per week.
What happens next??? |

The Canadians did this 40-odd years ago, and changed from CF- to C-, thus freeing up thousands of new possibilities. As I see it, starting a VI- prefix would only cause confusion; what if VH-ABC and VI-ABC are on the same frequency at the same time? |

Lots of software will need to be updated.
It was set up like this for a very good reason, like when Qantas wet-leased that 747-123 that still had a US registration and with PH-MCF. Don't know about non airline software. |

With quite a lot of commercial flight operations using the airline flight numbers these days for radio comms, the problems may be more likely administrative rather than operational.
Adding another letter on the end of the existing three letter suffix seems a reasonable solution. The British and the French operate thusly - and have done so for years - so any potential issues there would seem to have been resolved to the satisfaction of all parties. Where ops require aircraft identification by rego rather than flight number (or military designation), more precise radio procedures may be required, and everyone needs to be alert for the possibility of potential errors, but surely we are up to that. The expansion of data base requirements at all levels to fit the extra character needed could be something of a challenge, but we came through Y2K pretty well unscathed. In any event - we already have RAAus aircraft in the operational mix using the 2+4 numerical combinations, so changes in the mainstream aviation system should be quite workable if and when they become essential. Finally, from what read, I think ICAO may well need to be involved in any change anyway. |
1500 new alphanumeric rego marks released. https://services.casa.gov.au/CSV/availablemarks.pdf

Got as far as 82I and 82O. Might get away with radio calls but what about when painted on side of aircraft?

'ate VW sounds fun
