Boeing 737
Forwarding:
Travel, don't buy a Boeing 737 plane ticket, 737 in the first design when the engine is small, then in larger engine to find the location of the original design to hold, in order to avoid landing gear too short wheeled (too short) may have been sucked into the engine is too close to the ground and the hidden trouble of the foreign body and the engine position adjustment, forward and raise the height of the engine, resulting in engine exhaust gas blowing the main wing (large wings) cause premature separation of the wing lift layer (is cannot take off large Angle, cannot take off looked up too high), Boeing have not done a lot of Boeing did the most unreliable thing,They simply don't require pilot Angle of attack, later found do not actual, Boeing and dry the second unreliable, they installed a set of RIGS, the plane very simple rough forced the plane his bow, but added the RIGS is temporary so reliability is not standard, often a cow force plane automatically lowers the head (here you ask is not standard can hold?Because Boeing is big company, the test is not enough can rely on famous face) and the simple bow force system is a pain in the neck of all pilots fly Boeing 737, recently the system's acting up again (convulsions that before but it was as if repaired, until recently), so don't choose a Boeing 737, travel and other Boeing 737 crashed twice in recent make mend modify later, 737 will never be able to make the best modification scheme (landing gear change high) because extended the gear can't receive into the landing gear compartment, and want to increase the landing gear compartment is equal to the plane down to remake,The only way is to add a set of sensors of forced bow system, so that the sensor has a backup function (to avoid exhaust), and upgrade the software of forced bow system to increase reliability, and then take a Boeing 737 when they are improved, other Boeing planes do not have this problem, only 737.
There must be some smart people here who wonder, "if you know the problem, why don't you make an improvement on the new model?"
Good question, here's why.
Since 737 has produced nearly thousand, is Boeing's fiscal beams and redesign will consume 737 Boeing massive financial and corporate reputation (but don't affect reputation instead crashed a few, such as there was something wrong with private cars don't affect the corporate image, but not a public recall a certain model, sales over the bottom), again is if the new model 737 fix this problem, so before the production of 737?You can't repair it, you can't refit it, you're bankrupt.The only thing to do is to be thick-skinned and tough, and that's the harsh reality...
