Which of the following describes how you determine if a low visibility takeoff can be performed?

The determination of whether a low visibility takeoff can be performed is primarily based on comparing the runway visual range (RVR) values against the minimum required visibility criteria specified for that operation. RVR is a direct measurement of visibility and is crucial for pilot decisions during takeoff in low visibility conditions. Each airport and runway may have specific RVR requirements that must be met for safe takeoff operations.

Using RVR values allows pilots to objectively assess the visibility conditions against standard regulations and operational guidelines for low visibility takeoffs. In contrast, checking previous takeoff records or consulting exclusively with the flight crew does not provide the necessary real-time assessment of current visibility conditions. The aircraft operational handbook, while useful for understanding the aircraft's capabilities and limitations, also must reference current weather conditions, making RVR data the most direct and relevant factor for decision-making in low visibility scenarios.
