1、精选优质文档-倾情为你奉上1. An auto discharge fire extinguishing system provides fire extinguishing capability to the lavatory waste compartment. Extinguishing is accomplished by flooding the lavatory waste compartment with an inert gas. The extinguishing system consists of a heat activated extinguisher bottle
2、and a temperature indicator. The lavatory fire extinguisher bottle is mounted inside the lavatory cabinet assembly with the discharge tubes extending into the waste compartment. The extinguisher bottle contains fusible tips which have a melting temperature of 174 degrees Fahrenheit (79 degrees Celsi
3、us). When a fire or overheat condition occurs with the waste compartment temperatures rising to 174 degrees Fahrenheit, the tips will melt causing the bottle to discharge. The temperature indicator in a vinyl plate containing 4 heat sensitive patches. Each patch will change from gray to black when e
4、xposed to temperatures from 180 degrees Fahrenheit to 250 degrees Fahrenheit. This indicator should be periodically checked and if it indicates an overheat the bottle contents should be checked by weighing.1 In what way does the fire extinguishing system put out fires in the lavatory waste compartme

Eros is short Eliminate Range Zero System-range zero meaning collision. Basically Eros is a computer system that measures, with gr
10、eat speed and precision, closing speed (the speed at which two objects are approaching each other) and range (the distance apart of the objects). Eros can warn aircraft approaching each other at jet speeds and can provide protection for as many as a thousand aircraft in a wide area. The pilot of an
11、Eros-equipped aircraft heading for a collision hears warning noise in his earphones when his airborne computer calculates that he is within thirty seconds of half a mile(whichever occurs first) of another aircraft. At the same time, a flashing red arrow on the devices indicator panel instructs him t
12、o descend. Simultaneously, in the other aircraft, the signal is automatically reversed: The flashing arrow tells the pilot to climb. The newer Eros II system can accommodate a total of two thousand aircraft at one time within a 140-mile radius, Every three seconds, each Eros-equipped plane automatic
13、ally reports to ground stations and to similarly equipped aircraft its precise range, altitude, and approach rate. The producers of Eros, the McDonnell Douglas Corporation in The United States, are now studying the fitting of Eros collision-avoidance systems in all sizes and types of aircraft. Autom
14、atic systems such as Eros will do more than make the sky safer: they will also lighten the work of air-traffic controllers and increase the efficiency of airports.1 Two aircraft at range zero means _. (B)A a near missB a collisionC supersonic speed D wingtip separation2 As a computer, Eros was desig
15、ned to measure _. (A)A closing speed and rangeB an aircrafts altitude and distance from an airportC both A and BD neither A nor B3 The device gives its first warning to pilots of two Eros-equipped aircraft within _. (C )A thirty seconds of each other B half a mile of each otherC both A and BD neithe
16、r A and B4 The device works by giving _.(C )A a warning noise in the pilots earphonesB instructions to ascend or descendC both A and BD neither A nor B5 Details about the Eros II system indicate that _. (D)A aircraft coverage of the device has increasedB ground stations are included in the systemC the device measures altitudeD all of the above
