A-Z of course. Letters can be numbers, too. I often need to count from
0-F instead of 0-9.


When are letters numbers?

Generally in any base base 10. Base 36 for instance uses the digits 0
to Z - so every letter of the alphabet is a number.

Hex is very common (0-F), but we do have one system that uses base 36.
Base 64 encoding is also common (in which case 'a' is a different number
to 'A')

Not really. By having another letter, you get 25 times the number of
possible combinations. That should last for a while.

Actually, they have C-Fxxx C-Gxxx C-Ixxx (for ultralights). This gives three
times more combinations. While other letter combinations are available, some
are already in use (countries such as Chile CC, Cuba CU, Nauru C2, Morocco
CN, Mozambique C9, Uruguay Cx). See
http://www.lentoturvallisuushallinto...rcraftnational for a list (note
that Canada is missing the CG... probably a typo).

Not a typo. It lists C and CF as prefixes. C is the current style, and
CF the old style still on many airplanes. It gets converted to C-FXXX
upon repaint. There are no CG-XXX airplanes.
A related funny: Four of five years ago we were flying a 180 to
Tucson, via Salt Lake. Here's how the conversation went:
Us: "Salt Lake Terminal, Canadian Cessna 180 Charlie Foxtrot India
Alpha Charlie 15 miles North at 7500, Southbound for Provo."
Them: "Canadian 180 Charlia Indie Alph...." Click.
Them: "Canadian 180 Charlie Alphia Ind..." Click.
Them: "Canadian 180 Charlia Alphia..." Click.
Them: (laughter in background): "Canadian 180, stay east of the
highway."

I beg to differ, as I currently fly a C-Gxxx plane.

You can also search the database at the TC site
http://www.tc.gc.ca/aviation/activep...e.asp?x_lang=e
for available marks, and see that there are plenty of C-G availble.

Not necessarily. Aircraft built before some cutoff date (1974?) may keep
the CF-XXX style of registration if they wish. I think that you still
appear in the TC database as C-FXXX.

Does Canada use a 25 letter alphabet? Which one got canned?
