Under which visibility conditions should the Captain conduct the takeoff (ground roll through cleanup)?

• A. 1600 RVR or less / 1/4 SM or less if RVR is not reported / <=5000 ft runway (Lands on a CAT II approach)
• B. 1000 RVR or less / 1/8 SM or less if RVR is not reported / <=4000 ft runway
• C. 2000 RVR or less / 1/2 SM or less if RVR is not reported / <=6000 ft runway
• D. 600 RVR or less / 1/6 SM or less if RVR is not reported / <=7000 ft runway

Answer: (A)

Takeoff minimums for CAT II operations are about what visibility is required to safely begin and complete the takeoff when precision guidance is being used. With CAT II, pilots rely on instruments plus a limited visual reference, so there are published minimums: a reported RVR around 1600 feet (or, if RVR isn’t reported, a visibility of about 1/4 mile) to start the takeoff, and the runway must be suitable for a CAT II operation—typically a runway of modest length (often up to about 5,000 feet, depending on the airline and aircraft) to ensure there’s enough runway for the maneuvering and potential abort if needed.

That’s why the option listing 1600 RVR (or 1/4 SM if RVR isn’t reported) and a runway length up to around 5000 feet aligns with common CAT II takeoff minimums. The other choices propose much tighter or looser conditions that don’t match standard published minima for CAT II takeoffs.
