I posted the answer in this thread. It's because the Chief
Counsel's Office of the FAA has issued a written
interpretation saying it's OK. The reasoning is suspect,
but since it's an answer I want, and since the Chief
Counsel's opinion is right until it's overturned, I'll
follow it.

Could you please post a reference so the rest of us can do likewise?
