As ever, =E2=80=9Cit depends=E2=80=9D. Without knowing more about the conte=
xt, I can only appeal to my aesthetic sense and intuition.

Given that the computer doesn=E2=80=99t care if it=E2=80=99s 9 or 09, I=E2=
=80=99d probably store the value as 09. That will be familiar and natural t=
o a human pilot familiar with reading runway signs. Or an experienced techn=
ical writer used to documenting airport designs.

Don=E2=80=99t confuse the human is always a good design choice.
