Papa (Phonetic Alphabet)
The international radiotelephony spelling word for the letter P.
It is used to spell call signs, identifiers and words clearly over voice radio. Its prescribed spoken form is represented as ‘PAH PAH’.
The International Code of Signals assigns separate meanings to the single flag P, historically called the Blue Peter, depending on context. Those signal meanings should not be confused with using ‘Papa’ simply to spell a letter.
