It was difficult for me to discern between "AFFIRMative" or "NEGative". Listening a second time I believe it was 'affirmative', but it troubles me that it wasn't immediately clear. Why do these binary words share trailing syllables? Seems like this is inviting trouble...
If you listen just before the taxiway question, the controller says "Do what you need to do", then "Can I use the taxiway?" then controller says "Firmative"....
Whuts - You may have misunderstood the point of my comment. I understand in context that the answer was, 'yes, use the taxiway'. My point is that it's too easy to mistake "Firmative" from "Negative" over a garbled, stepped-on radio transmission. "Firmative" is even worse than "Affirmative" since it's the exact same number of syllables.
My question is, since aviation speak is intentionally clear, sometimes to the point of absurdity, why are the words for "Yes" and "No"- words that are polar opposites - so similar to each other? This seems like a glaring bug in the system that should have been squashed decades ago.
