ProblemWhat it solves
The problem this tool solves
Picking a cruise altitude by hand from the FB product is tedious, and the 0 °C crossing has to be interpolated between reported levels. The Copilot returns the wind/temp stack for your route with the freezing level already derived — and says "unknown" when the station does not report enough temperatures to locate it.
Example interaction
Pilot asks
Winds aloft over KDEN at 12,000?
Copilot responds
12,000 ft: 280° at 34 kt, −8°C. 9,000 ft: 270° at 22 kt, −2°C. 6,000 ft: 260° at 15 kt, +4°C. Freezing level ~8,000 ft MSL (interpolated between the reported 6,000 ft and 9,000 ft levels). Tailwind component favors the higher altitude eastbound.
