What altitude range does the Wind and Temperatures Aloft Forecast (FD) cover?

The Wind and Temperatures Aloft Forecast (FD) provides crucial information for pilots regarding wind and temperature conditions at various altitudes. This forecast specifically covers the altitude ranges from Flight Level 030 (FL030) to Flight Level 180 (FL180) and from Flight Level 240 (FL240) to Flight Level 530 (FL530).

This dual range is important because it encompasses areas where many aircraft typically operate, providing essential data for those cruising at higher altitudes. The first section, from FL030 to FL180, is especially significant for regional and lower altitude flights, while the range from FL240 to FL530 is more relevant for higher altitude, longer-range operations, such as those undertaken by commercial jetliners and other high-flying aircraft.

Other altitude options do not encompass the full range required for understanding both low-level and high-level flight operations. For example, an altitude range limited to FL010 to FL100 or FL200 to FL400 would not provide the comprehensive data necessary for all stages of flight, particularly for those flying above FL240. Similarly, covering from ground level to FL250 does not include the higher altitude predictions that are necessary for certain airspace operations.
