According to the 1-2-3 rule, when should you check the weather conditions?

The 1-2-3 rule emphasizes the importance of monitoring weather conditions at different stages of a flight. Checking the weather conditions 1 hour before departure is critical to ensure safety and preparedness for any adverse weather conditions that may affect the flight.

Additionally, monitoring the weather for 1 hour after the estimated time of arrival (ETA) at the destination allows pilots and crew to anticipate any changing weather that may affect landing or subsequent travel plans after arrival. This proactive approach helps in making informed decisions regarding route adjustments or delays, which is vital for safety and operational efficiency.

This timing also allows for adequate response time for any necessary changes to the flight plan based on the latest weather data, ensuring the safety of the flight and its passengers. Overall, adhering to the 1-2-3 rule ensures that pilots are well-informed and prepared for varying weather conditions throughout the flight journey.
