What should I do if a warning is displayed on the flight?

Don’t worry, apps such as Feichangzhun and Hanglvzongheng will mark “early warnings” for flights based on weather conditions, traffic control, etc., which only represent a prediction and are generally not very accurate. I also encountered several warnings because the previous flight was delayed, but later it all took off on time.

It is a civilized way of saying that flights cannot take off and land as scheduled, such as flight delays caused by weather.

Early warning signals consist of names, icons, standards and defense guidelines, and are divided into typhoon, heavy rain, blizzard, cold wave, strong wind, sandstorm, high temperature, drought, thunder and lightning, hail, frost, heavy fog, haze, road Freezing etc.

The levels of early warning signals are divided into four levels based on the degree of harm, urgency and development situation that meteorological disasters may cause: Level IV (general N), Level III (serious), Level II (serious), Level I (extremely serious) is indicated by blue, yellow, orange and red in order, and is also marked in Chinese and English. Meteorological disaster early warning signals and defense guidelines.

It is a normal workflow for aircraft to cancel warnings. After each flight mission ends and the aircraft docks safely, the flight attendant will cancel the warning and conduct cross-confirmation checks before opening the door. If the warning is not canceled and the slide is released, this is a serious work error.

Aircraft warning generally refers to the cabin door emergency escape device warning system. After the plane closed the door, the flight attendant set the door emergency escape system to an early warning. The purpose is to directly activate the inflatable slide after an emergency landing or crash after various emergencies during flight.
