Awol57,
I'm asking where the phrase was used in Australia? Where BigPapi was cleared the option? On multiple occasions. If it's at a RAAF controlled aerodrome, it doesn't count. The RAAF controllers work under very different rules than Civilian.
I worked very briefly in a tower. However, I'm talking from a pilots perspective, I've never heard it used in 30 years of flying.
It's been established that it's in AIP.
