No. The identifiers are identical but for the 0 and the S: N880P and
N88SP are both based at VNY.


Then you're just going to have to live with it. The letter O is not used in
identifiers to avoid confusion with zero.

One could just as easily decide that the number 0 is not used in
aircraft identifiers to avoid confusion with the letter O. Nothing
would actually have to change.

Are the aircraft the same type?

I don't think so, but the VNY controllers don't call out the aircraft
type. They always open with "November".

One is not free to decide that. The letters I and O are not used for
aircraft registration in the US. FAR 47.15(b) would have to change.


§ 47.15 Identification number.

(b) A U.S. identification number may not exceed five symbols in addition
to
the prefix letter "N". These symbols may be all numbers (N10000), one to
four numbers and one suffix letter (N 1000A), or one to three numbers and
two suffix letters (N 100AB). The letters "I" and "O" may not be used. The
first zero in a number must always be preceded by at least one of the
numbers 1 through 9.

You are free to open with the type regardless what the controller does.

Bummer.

Yes, but that's not the issue. The issue is what to do when both planes
are in the pattern you hear a controller issue an instruction to
"November eight eight syrah poppa...."

You say, "Say again".
