The command deletes to the next 'A' - so it depends on the current position.
As this is not defined I assume that position in column 0 is wanted.

	:%s/^.*A//

Well, this will delete to the last  'A' in every line.
This one should delete to the first 'A' of every line:

	:%s/^.*A[^A]*$//

	sed -e "s/^.*A//" file > outfile

:%s/^[^A]*A//


pretty much the same with sed:

sed -e 's/^[^A]*A//' filename

Never forget "normal" - makes life very simple very often!
        :g/A/ normal dfA
However, the screen flashes a heck of a lot - as vim hits all the lines that
have an "a" but not "A" (my settings are always "ic").  If that's a bother
":set noic" first.

Emacs:

M-x query-replace-regexp RET ^[^A]*A RET RET

Then, hit "!" to skrip the yes/no questions.

- it's wrong because every line like
bbbbacccc
  will be replaced by
cccc

  If you want to replace first 'A 'in every line (not 'a') then the
best way in Emacs is the following:
M-x  eval-expression RET
(let (case-fold-search)(replace-regexp "\\(^[^A\n]*\\)A" "\\1" nil)) RET

  To replace last 'A':
M-x  eval-expression RET
(let (case-fold-search)(replace-regexp "A\\([^A\n]*$\\)" "\\1" nil)) RET

  To replace all 'A':
M-x  eval-expression RET
(let (case-fold-search)(replace-string "A" "" nil)) RET
