But unfortunately, we had to wait for nearly one hour before it came. but the time we changed the plane to take off was two hours later. Question: How did they get back to the gate?

A runway strip including a precision approach runway shall be practically extended from the distance of at least 150 meters from runway centerline with code number 3 or 4 and at least 75 meters with code number 1or 2. Question: How does the runway strip of a precision runway extend from the runway central line?

When the aircraft was at 2000ft, flaps were lowered from 30 to 40. After passing the middle Marker, the airspeed was decreased to 140 knots. At two miles from touchdown, rate of descent varied by at time only by 100ft. In the end, a perfect landing was made because of these conditions. Question: What was the condition at 2 miles from touchdown?

In the serious emergency situations, pilots make MAYDAY call requiring immediate assistance. In other serious situations, pilots make PANPAN call, PAN means possible assistance needed. This is used when they stay in emergency, but the dangers don't threaten the flight safety now. Pilots may request take necessary steps to face the problem. Question: What does the panpan abbreviation P.A.N. mean?

The airspeed indicator is marked nautical miles per hour, called knots for short, knots are measured as a speed based on nautical or sea miles, aviation uses both nautical or statute miles for distance and speed. Question: Which of the following is not mentioned?

My friend is really angry with the airline. Last week, he had a reservation for a flight Shanghai for an important meeting. But he didn't get on the flight even he got to the airport ahead of time. The airline apologized and offered him money, but he refused (拒绝) the money and took the legal action against the airline. Question: Which statement is correct?

Some kinds of weather can severely degrade the performance of the aircraft, such as turbulence and mountain waves. Icing conditions can be also very dangerous, pilots need to know the freezing rain, clouds or drizzle to cause ice buildup on critical surfaces of aircraft. Question: What kind of weather causes severe icing conditions?

A flight director is found on the primary flight instruments on these chevron indicators or a pair of vertical and horizontal bars. Both chevron and bar flight indicators are mainly displayed which means by flight towards them, regain or maintain the programmed flight path. Question: What is the main topic in the statement?

Crew Resource Management, formerly known as cockpit resource management, is a process using all available resources such as equipment, procedures, and people to achieve a safe and efficient operation of flight. Question: According to the statement, what is the goal of CRM?

M1: There are different types and degrees of preflight inspection. M2: Oh, yes, the individual components will be replaced based on the numbers of landings, flying hours and other criteria. Question: What are the criteria for replacement of individual item?

During the instrument flight, most of your scan time will spent on the attitude indicator, you will realize the instrument flying is much more precise than your visual flying, this is because now you pay more attention to the performance of the instrument when you used to spend time looking out of aircraft. Question: What is the speaker mainly talking about?

The aircraft is flying from Beijing to Paris, when it reaches its maximum cruising level, the cabin is pressurized to 8000ft, this requires the pressure difference of 8-9 psi. Question: In this statement, what is 8 to 9 psi?

The aircraft has just taken off, the crew expect to turn right and proceed to waypoint YB, which is the ex-point on the SID. When passing 600m, the departure controller instructed them to turn right and proceed to VINI, a waypoint the crew doesn't understand and recognize, so the crew decided to contact departure control. Question: Why does the crew need to contact departure control?

In-flight icing conditions exist with air temperature below freezing, but some water in cloud is liquid. The most important feature of cloud that fix. ice buildup is amount of liquid water in the cloud and the signs of water droplets. Generally, the first signs of icing problems are decreasing airspeed, decreasing climb rate and higher normal power setting for selected airspeed. Question: What is one of the first signs of an icing problem?

A British Airway B737 skidded off the runway at De Gol airport in Paris, on September 16, 2006 when landing in bad weather. There was no fatality（死亡，致命）, then passengers and two crew members were injured. The plane received minor structural damage. Question: How many people died in the accident in Paris?

Before clearing an aircraft for takeoff, it is the responsibility of Tower controller to maintain proper spacing between aircraft. This varies, depending on the route of fight, the type of aircraft, and weather conditions. At time of low visibility, the controller uses surface radar to monitor the position of each aircraft on the ground. Question: What do controllers use in low visibility conditions?
