"Whoop Whoop pull up"
As someone that sits on the other side of the FD...I have a question.....
My understanding is that "Whoop Whoop pull up" is a much greater alert/warning than "caution terrain, caution obstacle, ect. What I would like to know is why the phraseology "Whoop Whoop" is used?
Why not "Caution pull up?" or "Warning pull up"? Why are the words "whoop Whoop" indicated as having a stronger sense of urgency than "caution or warning" when these alerts/warnings are activated in the FD?
