What are the main checks before the plane takes off?
1. Weight and state of aircraft;
2. Movable objects in the fixed cockpit and all control systems are in a relaxed state;
3. Carefully check item by item according to the flight manual;
4. Check the fuel supply required for the flight in the plan, calculate the fuel reserve for 15 minutes for takeoff and climb, and the fuel reserve for 45 minutes for waiting over the destination;
5. Take oil samples from the bottom of the tank or the suction valve under the engine, and put them in a transparent container to test the oil content and miscellaneous quality.
The range of activities of large, medium and small aircraft in the air The aircraft flying in the sky and the car running on the road, also have their own “traffic rules”.
Different aircraft types fly at different altitudes.
Below 3000 meters, which is generally the range of activities of small aircraft;
Above 3OOO meters is the range of large and medium aircraft.
The so-called “ultra-low altitude flight” is 5 to 10 meters above the ground or water;
The so-called “low altitude flight” refers to the distance from the ground or water 100~1000 meters;
Similarly, “hollow flight” 1000~7000 meters;
High altitude flight “refers to 7000~12000 meters;”
Stratospheric flight “means above 12, 000 meters.
Aircraft must maintain a certain vertical interval between each other. Current regulations of civil aviation in China are above 6000 meters to fly above the air, and the vertical interval is 600 meters, to ensure flight safety and traffic.
Numerous investigations and studies at home and abroad have proved that air traffic is the safest.
Air China, for example, has maintained a safety record for 45 years.
The United States has also made statistics on aviation safety, in 26 months, the major airlines in the United States completed more than 500 million passengers, passenger turnover of more than 5.4 billion people miles, takeoff and landing 10 million sorties, without a major passenger plane accident.
It turns out that air transport has the highest safety factor among all forms of transport, four times higher than rail, 15 times higher than road, and 132 times higher than taxis and cars.
The latest market dynamics at any time to see, please pay attention to.
