The issue is still not clear for me. Is there an official (written down in documents) way to request it correctly?
For ex., if I landed on RWY 27 what do I need to report to the ATC?
- Request backtrack rwy 27
or
- Request backtrack rwy 9 (because I already turned 180 degrees and now it's rwy 9 from my perspective?)
Personally, I think the best way to request it would be:
- Request backtrack from the end of rwy 27 (even though it's slightly longer, but eliminates any ambiguity)
