"The LSO will respond with the coolest voice he can muster, telling you the winds and the deck state if it's not steady enough for the lens (which is stabilized and moves with jack screws to counter the sea motion). It will be something like this:
"Roger ball, 22 knots, axial."
That means he understands you can see the lens, so he expects you to fly it. "
