Is frost considered hazardous to flight?

Frost is indeed considered hazardous to flight primarily because it can significantly impair an aircraft's performance and handling characteristics. When frost forms on the wings or control surfaces, it disrupts the smooth airflow over those surfaces, which is critical for maintaining lift. This disruption can lead to an increase in stall speed and a decrease in overall aerodynamic efficiency, making takeoff and climb phases particularly risky.

Additionally, frost can accumulate even on relatively warm days, especially in the early morning or late evening when temperatures fall. This can catch pilots off guard and lead to unsafe conditions if not addressed before takeoff. The safety protocols in aviation emphasize the importance of maintaining clean, frost-free surfaces to ensure optimal flight performance.

While other factors such as the type of aircraft and specific conditions can influence the severity of the hazard, the general stance is that frost on an aircraft is a significant safety concern that must be managed before flight.
