What is the takeoff minimum expression for non-precision and precision operations under Standard Instrument Rating?

• A. Non-Precision: 300-1; Precision: 200-1/2 or 2400' RVR
• B. Non-Precision: 250-1; Precision: 150-1/2 or 1800' RVR
• C. Non-Precision: 350-1; Precision: 300-1/2 or 2600' RVR
• D. Non-Precision: 400-1; Precision: 350-1/2 or 3200' RVR

Answer: (A)

Takeoff minimums are published as a two-part expression: a minimum visibility and a minimum climb gradient. The number before the dash represents the required visibility (or RVR equivalent), and the part after the dash shows the required climb gradient in feet per nautical mile. When you have a precision departure or operation (with vertical guidance), you can meet the minimums with a lower visibility than you would for a non-precision departure, and you also have the option to use runway visual range if it’s reported. So, for non-precision departures the minimum is 300-1, meaning a higher visibility requirement with a certain climb gradient. For precision departures you can meet the minimum with 200-1/2, a lower visibility accompanied by a 200 ft per NM gradient, or you can satisfy it using 2,400 feet of runway visual range (RVR) if that measurement is available. That combination of lower visibility or an RVR value is why the precision option is listed as 200-1/2 or 2400' RVR, making it the best match for Standard Instrument Rating takeoff minimums.
