If the temperature is below -40°C, what must the crew accomplish before flight view closeout?

When the temperature falls below -40°C, the aircraft and its systems are subjected to conditions that can affect performance and safety. In such cold temperatures, a thorough verification of the aircraft's condition is essential to ensure it is airworthy. The necessity for additional maintenance inspection arises because extreme cold can cause various mechanical and material issues that may not be readily apparent.

Taking off without ensuring the aircraft is in optimal operating condition could pose significant risks, including potential system failures or other malfunctions during flight. Therefore, conducting a further maintenance inspection becomes critical in this scenario, as it allows the crew to identify and mitigate any issues that may compromise safety.

While systems checks, de-icing, and fuel verification are all important aspects of pre-flight preparations, in the context of extremely low temperatures, the priority is ensuring that the aircraft has undergone rigorous inspection to confirm it is fit for flight, making the requirement for a maintenance inspection paramount.
