@ aviator4u
thanks for your reply.. cheers!

@radar contact
thank you:D i got it now |
@all
I suppose everyone might be having the ebook of Oxford book set here. I dont have the answer set for the POWER-PLANT book within :ugh: , just wanted to know, is this the case with every1..! :rolleyes: please do reply |
Is it BASIC GAS TURBINE... ?? :confused:

Answers to PowerPlant Questions
Hey buddy, If you give me your email id I can send you the answers to the power plant questions.
Cheers |
Uniform
In that case check your page numbers, you might be missing out on many pages, because I have the same book 4 Powerplant and there are about 20 questions for the first chapter(Introduction) in the gas turbines section. Chapter 2 is Air Inlets.

@Vertigo911
check ur PM |
anyone here has got roll numbrs or any sort of confirmation?:confused:
keep posted! happy studyng!:ok: |
Anyone here know the kind of electrical based questions asked last time. If any of you have an idea, please post
|
@ superflytnt
definition of EMF.
power rating of generator. calculation of battery backup power [Ampere-Hour] in which many of my frnds screwed up cz cz they miscalculated or something n misunderstood d qstn. i rem the qstn somewhat like - an 150Ah battery will provide 450amps for how long???? some chose 3hrs :ugh: := bt the answer was 20min :ok: |
@thearsenal..
As far as I know.. 150 A is how much the battery can hold.. And 450ma.. is what you are demanding out of it.. so therefore it can just hold on for 20 mins.. P.S. On a side note.. if thearsenal means the epl team arsenal.. It's a sad sad day.. |
15 hrs * 10 A = 150 Ah
x hrs * 450 A = 150 Ah x hrs = 150/450 x = 1/3 hrs or, x = 60/3 = 20 mins |
@thearsenal
dude its not ampere/hour,its ampere hour,unit of electrical charge...for ex-a current source that is one amp-hour can deliver one amp for an hour or two amps for half an hour or sixty amps for one minute. so it has to be 150amp hour/450 amp=0.33 hours=20 mins.

book for jet engines
I you really want to study deep..... study from Mike Burton
But its to much just go through grounds up and if ny problem in understanding just see videos in you tube . they have explained in detail |
Temperature at 39000ft is -56.5*C the deviation from ISA is?
A) ISA+6 B) ISA C) ISA +7.5 D) ISA +5.5 ? |
@ aadityaslg
The answers is option B) ISA because temperature remains constant at -56.5 from 36000-65000 feet according to ISA |
@Uniform
The answers for the powerplant book is given in the last few pages :) |
Yeah.. that was a cheeky one from Jet Airways.. :)
I mean those questions look n in fact are very simple and basic, but then they give u little time to think about it.. Happy Studying! |
boeing v/s airbus
:hmm:
In the long run,which would be awise choice? Being with the BOeing fleet or an Airbus fleet? 320s have begun to flood the skies.. More AirNm/g , FBW...many advtgs Any valuable i/ps on this topic is welcome. |
@cobracommander
I suggest you start a new thread for your debate |
Any confirmation on the exam date yet?
|
@cyrilroy21
Thank you :) but my ebook didnt had the answers anywhere. probably some old version... anyways i got that download again..!! :ok: |
AMPERE HOUR ques floating...FYI
A 10 amp-hour battery can provide ten amps for one hour, or one amp for ten hours. The capacity is a product of current and time. The more proper unit would be the watt-hour, but you can find that by multiplying voltage and current (i.e., a 10 Ah 12V battery is a 120 Wh battery).
Note that this doesn't mean you can get 100 amps out of that battery for six minutes. Maximum current is limited by the physical construction of the battery. If you draw current out too quickly, the chemical reaction becomes limited, and this can even cause permanent or catastrophic damage (read: explosion) to the battery. Usually, a battery is designed for a specific current drain and this will be current at which the amp-hour capacity is measured. So a 150 AH battery can only provide 150 amperes of current(if its 100% efficient which is never true. A/c batteries shud be atleast 80 % efficient). For a system of 450 Amperes three batteries ,150AH each,must be connected in parallel to serve a system of 450 Amperes for an hour... Also bateries have power rating..that must also be considered . In winters you must need atleast 33% buffer for battery back up: More AH to be used in cold temp.. fly safe |
were the questions in jetairways exam from oxford???
|
@harsh786techy
nice..!! :) so according to the explanation given, answer to Radar_contact's question a 150Ah battery will provide 450amps for how long???? would be?? not 20min ofcourse.. or we can just say its just a theoretical question and not technically applicable :ooh: |
@Uniform
A 150 Ah rated battery cannot sustain a system of 450Ah...In short it will not provide current to 450 Ah...thats what my knowledge says..Practically the battery will leak,explode, or get damaged.
I find this ques irrelevant or one of the option must be "Irrelevant".. Only three 150 Ah batteries can sustain a system of 450 Ah, that too connected in parallel... fly safe |
Can all of you guys, trying to show their knowledge over here,start a new thread n discuss it over dere????and keep this thread to let ppl know any updates about the exam dates n recruitment process...
|
cheers guys thanks fr the response really helpful.
|
errors of turn and slip indicators
can some1 elaborate please |
written exam on the 27th feb 2011
|
is it tentative or sure.?? and what about the call letters??
|
written exam on the 27th feb 2011 |
Regarding the mental ability papers
Can any-one suggest me any books for the same?
|
hi..
can any1 tell me what is the procedure to get the confirmation mail from jet airways to take the exam with lapsed ir. herd a few ppl have received the confirmation mail from the HR of jet.. do u need to personally contact the concerned people... ????? or is there any other way.....??? |
@Learjet35alpha
Confirmation mail??? I dont think everyone with lapsed IR need to get an individual confirmation regarding same. Its been already confirmed that we dont really require a current IR, but still you can e-mail the jet HR department for your satisfaction. @all few queries if anyone could explain 1. What is the theoretical maximum range that an aircraft at FL420 will obtain from a VOR beacon situated at 400' amsl? ans - 276nm 2. What is the approximate maximum range that an aircraft flying at 25000' would expect to obtain from a VOR beacon situated 900' amsl? ans - 198nm whts is th difference between THEORETICAL MAXIMUM RANGE and APPROXIMATE MAXIMUM RANGE?? :ugh: |
has anyone got reply from jet yet ?
|
@uniform
the theoretical maximum range is the range of radio signal as determined by the formula for line of sight waves (1.25(rootH1+rootH2)).
the theoretical range does not take into account various factors such as signal attenuation, transmitter power, propagation conditions. in reality, the maximum range is actually less than the theoretical range. regarding the second question, no idea how it is calculated !! |
@ VT-ASB
i applied same line of site formula but not getting any of those answers :ugh: also dint find the solution anywhere
que are from Oxford : Radio Navigation chapter 4 VOR |
The approximate maximum range of a VHF signal is given by the formula:
VHF Range in nm = the square root of (1.5 x altitude in feet) Example: At 7,000 ft AMSL, approximate VHF range = square root of (1.5 x 7,000) = square root of (10,000) = 100 nm. |
Hello guys,
All the folks here who has contacted Jet Airways HR about there queries and have got a reply from them, can they please again contact them and try to know when Jet Aiirways is planning to conduct the exam. Fly safe |
