Automation promises great results for the controller. Technical advances are expected to improve the performance of the human-machine system, and controllers assumed to be flexible enough to adapt to the new working environment. But partial automation can actually increase the risk of error attributable to human operators. This is because they are expected to monitor systems that are harder to understand and to exercise their skills only intermittently. In the US, the FAA’s Automated En-route ATC programme is designed to detect potential conflicts up to 20 minutes before they occur. It generates a resolution immediately, and provides simulation capabilities.As a result, the controller deals only with aircraft that the system says need attention, and while he/she has to rely on the system to detect problems and provide resolutions. The controller resolves them as soon as they are detected rather than wait to assess them visually on the situation display, so the focus of attention shifts from tactical monitoring, problem analysis and coordination toward strategic planning tasks.Many French controllers query this philosophy. Applied to French airspace, it could, mean a controller has to transmit a revised clearance to an aircraft in his sector to avoid a predicted conflict in another sector with an aircraft currently in a third. And if he disagrees with the clearance, he will have to propose an alternative without having access to information on what is happening in the other two sectors. If the controller’s role is limited to transmitting machine-generated clearances, he will soon lose his ability to make control decisions. CENA is developing an alternative at its Toulouse training centre. The En-Route Air Traffic Organizer (ERATO) is a software program to cope with what CENA terms the capacity barrier. It takes all the information available from sensors and flight plans, plus intention data obtained by data link from aircraft to create a working airspace model. The scenario it presents can identify and prioritize potential conflicts, and offer tool to resolve them. To do this, ERATO enlists the support of artificial intelligence techniques. It can describe the mental activity of controller, and assess deterioration under pressure of time, fatigue and stress. The central question is to identify the conditions under which the controller’s knowledge ceases to be accessible. It also sets out to identify and predict sources of error.4.ERATO is designed to （ ） ．

Lack of familiarity with the English language and poor radio transmission discipline is a problem for foreign pilots，Quite often they gossip in Mandarin on a main control frequency about the price of vegetables, said one pilot. There are still many areas in China where position reports are made on HF radio and despite China’s prowess in launching satellites for foreign customers, satellite communications are still a long way from providing a viable alternative. Pilots also find the controllers use draconian power, possibly as a result of military influence. Controllers have closed an entire airway due the weather. They have been obliged to do this because of the military’s refusal to allow deviation from the airway. Similarly traffic has been obliged to divert from airport because the controllers considered the weather to be unacceptable. This can be embarrassing for pilots who have flight planned fuel reserves with the actual and forecast weather. Fortunately, as a result of pressure from the airlines, the Chinese are starting to yield to the standard practice of allowing the aircraft commander to judge conditions himself before making an approach. China has been cautious in venturing into the field of satellite-based navigation systems. Forty eight of China’s airport are now equipped with Instrument Landing Systems (ILS). Beijing and Shanghai Hongqiao are the only airports with Category II ILS approaches, and with the addition of Guangzhou airport in the south, are the only international gateway airports in China. Pilots operating regularly in China are optimistic about improvement. General operations manager of Dragon Air Felix Hart says that in the last three years he has noticed enormous improvements, especially in the level of English language comprehension. Another pilot said: Although they are still reluctant to give radar vectors, they will often tell us how far we are from the ILS centerline and we know that they have us on radar when they ask us to squawk our SSR transponder identity. He cautions:Many controllers lack terrain awareness, so we have to be very careful about following their instructions. 5.Which of the following isn’t true?

A Beech Bonanza, N 3794N, crashed at night approximately 5 miles northwest of the Mason City Municipal Airport, Mason City, Iowa, at approximately 01:00, February 3, 1959. The pilot and three passengers were killed and the aircraft was demolished.The aircraft was observed to take off toward the south in a normal manner, turn and climb to an estimated altitude of 800ft, and then head in a northwesterly direction. When approximately 5 miles had been traversed, the tail light of the aircraft was seen to descend gradually until it disappeared from sight. Follow this, many unsuccessful attempts were made to contact the aircraft by radio. The wreckage was found in a field later that morning.This accident, like so many before it, was caused by the pilot’s decision to undertake a flight in which the likelihood of encountering instrument conditions existed, in the mistaken belief that he could cope with en route instrument weather conditions, without having the necessary familiarization with the instruments in the aircraft and without being properly certificated to fly solely by instrument. 5.What caused the accident?
