How can pilots find the weights of fuel and oil under various temperature conditions?

The most accurate resource for pilots to find the weights of fuel and oil under various temperature conditions is the TC AIM RAC 3.4.8. This section of the Aeronautical Information Manual provides detailed information regarding aviation regulations and guidance, including specifics about fluid weights and adjustments necessary based on temperature variations.

Using the TC AIM allows pilots to refer to standardized data that is recognized and accepted across the aviation community, ensuring consistency and reliability in calculations related to fuel and oil weights.

While other resources like the Aircraft Performance Manual, Flight Operations Handbook, and Pilot's Operating Handbook may also contain relevant information, they typically focus more on operational procedures or performance metrics rather than detailed fluid weight calculations under changing temperature conditions. Therefore, the TC AIM RAC 3.4.8 is the authoritative source for the most precise data regarding how temperature affects fuel and oil weights, making it the correct choice.
