Hotel Tango
My own experience is that controllers generally, for clarity, add "the long way around" in their tx when giving such turn instructions.
Thank you for this observation, as a Pilot and the owner/teacher of an English for aviation language school this is good to know, the rest of the message (below isnt't aimed at Hotl Tango... Just some observations..
With my students, in all classes we run a section about RT used in the United States, which is for my students to have a broader knowledge of how the USA breaks from the norms of most of the rest of the world. As a commercial pilot based in Brazil you will find that a lot of your interational flying is done to the USA and, infact ANAC (th Brazilian FAA/CAA or what have ya) have molded there English exam (to some extent) with this in mind. However, I think that it is absolutely fundamental that when my students leave to take their exams that I can sleep at night in the knowledge that they have received more than just enough education to perform, that they understand that infact, ICAO 4 is far from perfect and while I can not cover every eventuality in the time that we have, the student will certainly continue to consider and study the many differences that exist between reality and standard RT in the States. When I have the time, I will start another thread on this... However, ANAC here in Brazil are now actively lobbying and petitioning the USA to improve and starndardize its phraseology to be inline with (most of) the rest of the world.
With regards to the quoted text, I actually just called a student, who is a commercial pilot for a blue airline here in Brazil, a 10k + hours captain, who has just received level 5.... When I asked him to readback and then to explain the message "turn soutbound, the long way around" after explaining that he was currently climbing through 6000 and heading 030...... The read back was a tongue twister, he mumbled long as something between long and wrong - he was also unable to explain in Portuguese exactly what the controller wanted him to do.... Setting him up in the same position and saying... turn left heading 180.... there were no problems at all, both the read back, and his explanation of the situation were perfect.
