If an air plane has a circuit problem, how to detect it?

Question

Things like cellphone and computer can have circuit problems.
But air plane has lots more complicated circuits for sure.
If there's an error somewhere on a plane, how to detect an circuit error on a complicated electrical system?
Is there an unique error-detecting system working on a plane or something like that?

I'm doubting if it's possible to rule out every single problem on a plane, because things are too complicated out there on it. Well I guess there must be a lot of unsolvable technical problems on it...

Maybe a small problem won't cause an air crash but it's still professional to keep passengers lives, so how will they deal with it?

Answer 1

We DO trouble-shoot the daylights out of any problem with the aircrafts' electrical or electronic systems... As others pointed out, there is BITE (Built In Test Equipment) and are circuit breakers, and the pilots / crew know the location of each and every one. Part of the annual exam was being able to ID each circuit breaker while BLINDFOLDED !

If the problem occurs in flight, you isolate the system, rely on back-up systems, and then determine whether or not to continue the flight based on the severity of the fault. ALL faults are then written up and reported to maintenance.

It isn't TOO difficult to track down an issue in the wiring, and most SYSTEMS are simply swapped out with a new part if there are troubles. Just pull the box, sensor, indicator, or equipment and plug in a new one.

Answer 2

all modern aircraft has upgraded their electrical system.e.g on airbus.They have B.I.T.E(built in test equipment) system.This system is using electronic detecting system.The problem will be shown on the computer.If a problem occurs the system will detect it and shows whats components have been effect.On other aircraft they have an indicating system.If a problem occurs, it will show in the gauge on the cockpit.On ground,if they want to detect the continuity on the wire along the aircraft fuselage, they will use some equipment.E.g mega ohmmeter.There are so many equipment or tool that can use to detect the problem on the electrical system.

It relies upon on the fast. If it have been in any of the numerous electric powered issues that often fail in on an widespread basis operation on all varieties of airplane then all that could ensue is a breaker might pop and the maintenance human beings might swap out the undesirable merchandise. however the KLM flight lost off Halifax, NS develop into set on hearth by utilising an electric powered short. the hearth then destroyed the administration platforms and the airplane crashed. airplane are very complicated and there are an impossibly great form of not likely issues that ought to ensue. greater in all probability the fast develop into in basic terms a symptom of another failure, one information checklist suggested the acceptable automatic replace from the airplane suggested that it had lost cabin rigidity, this could point out a greater important structural failure. ought to and could and... nicely it rather is too early to invest. human beings at right here who're giving annoying and rapid solutions the two be attentive to not something or ought to be attentive to greater acceptable. the different reflects on the A330 are pushed from different computers and different electric powered platforms, you are able to lose an entire host of computers and hyperlinks and capacity and nonetheless have an, curiously, completely serviceable airplane... different than all the crimson flags warning of gadget mess ups. it rather isn't something your dad under pressure out including a vehicle battery and a few flex he pulled off a lamp. Avionics engineers are very careful and check out to isolate all available faults. in addition they layout and check out those airplane to proceed to exist miltiple lightning strikes devoid of platforms failing. does not mean that nature would not have a bigger blast than you accounted for, yet airplane stay away from storms too. it is going to be thrilling to establish what actual occurred.

Answer 4

Most newer A/C have backups systems for their on board computers, so if something fails they still can fly to the destination without an incident.

Answer 5

circuit breakers that will pop out if there is any electrical problem. in instance electrical system for the flaps, the circuit breaker named "flaps" will pops and isolate it. and if it is needed, the pilot can push it in again to re-connect the circuit, but sometimes it is limited for several tries because too much can cause fire.

Answer 6

they have circuit breakers that will pop if there is an issue to prevent overloading and fires. Also the onboard computer may advise you of an issue.

Answer 7

if you're in mid-air, call may-day but you might not survive
