　 Statistically, air travel is by far the safest way to tavel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil (零), many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne (升空的).

Fly on non-stop routes

Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.

Choose larger aircarft.

　 Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply (遵守) with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.

Pay attention to the pre-flight safety briefing

The information may seem repetitious (重复的), but it's worth listening to the flight attendants. And even if you've flown before, it doesn't mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.

Store things safely

Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence (气流).

Keep our seat belt fastened while you are seated

Cabin crew always tell you this, but it's important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.

Let the flight attendant pour your hot drinks

Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.
