What do the last two digits of an FB forecast element indicate?

The last two digits of an FB forecast element represent the temperature in whole degrees Celsius. This part of an aviation weather report provides pilots and other users with critical temperature information, which is essential for flight planning and operations. Temperature impacts aircraft performance, including fuel efficiency and lift capacity, making it an important factor in aviation safety.

Understanding the temperature forecast helps pilots anticipate weather conditions they may encounter during flight, such as potential icing or turbulence. By providing the temperature in whole degrees Celsius, the FB forecast element delivers clear and straightforward information that can be easily interpreted.

The other options address different weather elements, but they do not pertain specifically to the last two digits of the FB forecast element. For instance, wind speed, cloud cover percentage, and altitude are communicated through different parts of a weather report or use different formats, making it clear that they do not correlate with the last two digits seen in this context.
