Which statement about takeoff minimums for two engines is true?

• A. 1 mile or 5000 RVR
• B. 2 miles or 7000 RVR
• C. 3 miles or 9000 RVR
• D. 1/2 mile or 1000 RVR

Answer: (A)

Takeoff minimums set the minimum visibility a crew must have to begin a takeoff under instrument conditions. For a two-engine aircraft operating under standard procedures, the published minimum is one mile of visibility or an RVR (Runway Visual Range) of 5000 feet. Both numbers express the same threshold in different units, since 5000 feet of RVR roughly corresponds to one mile of visibility. This level of visibility gives pilots enough visual cues to maintain proper runway alignment, assess safe takeoff performance, and have a margin to abort if needed.

Higher minimums (two miles with 7000 RVR, or three miles with 9000 RVR) are more restrictive than the standard and would only apply if the operator or airport has published stricter minimums. A much lower minimum (half a mile or 1000 RVR) would be below standard and typically isn’t permitted without special approvals.
