ATP Radio aids DGCA Prep Questions

[livetokill22]

C. 094 is it?
you did not answer the above question as well bro. is the answer correct.

[Pulkdahulk]

LivetoKill - you will surely kill people one day onboard ...Just Kidding

aircraft is tracking away from a VOR

you read it as aircraft is tracking towards so what you did was 287-180= 107 + 14 Starboard = 121

its the other way round lol

read read the Question properly lol

cheers

[Pulkdahulk]

Nothing like that, I did not refresh my page. Basically as I study I post Questions so sometimes I do not refresh my page and I post new Questions..

cheers

[Pulkdahulk]

Yup, it was a trick Question from Oxford which I faltered myself too

I took 094 for VOR and applied variation to it only realizing it was a trick Question and that variation has got nothing to do with it, because radials are Magnetic and not true. Let see what others do..

084
V
10W
M
094

Assuming the maximum likely error in VOR to be 5.50
, what is the maximum distance apart that
beacons can be situated on the centre line of an airway in order that an aircraft can guarantee
remaining within the airway boundary?
a) 54.5 nm
b) 109 nm
c) 66 nm
d) 132 nm


answer :

its a 1:60 problem .

5.5 / 60 = 5nm ( width of an airway ) / x

x = ( 5 X 60 ) / 5.5 = 54.5

54.5 x 2 = 109 ( max dist b/w two VOR's )

Hey Guys,

Saw your little thread, where U guys are helping each other out with questions, it's nice to people still help each other....... I thought it was cut throat competetion out there these days......

I need some help.... I want to start studying for my ATPL, but I am not in India, so can't attend the coaching.....

Can U pls advise what books are in latest .....

Thanks

[Pulkdahulk]

PilotBaba - thanks for the gesture.

Well I myself did not take tuitions or classes for CPL and for the same ATP. I was not interested in doing ATP at all until yesterday and my name is on the list for this attempt.

But thanks to couple of pilot friends who have been pushing me everyday to write, so I am giving it my all with 9 days left to doing the best I can and Pprune is a great place to exchange Q&As

I think my knowledge still remains current because the Indigo Exam made me prepare really hard with me studying Oxford. So it really helps. Now how does having a frozen ATP will help, I do not know about that. But I believe ATP Rules for exams are changing this Year going to more than 8 subjects so when we have 3 subject, finish it now rather than later.


Pick up JAA Books like Oxford and Keith Williams. Practice all and read every chapter. You should be fine after that.

[pilotbaba]

Once upon a time I used to be very good about DGCA exams, but that was long time ago...

Whether they are 3 or 13, doesn't matter, if one studies right, it can be done. The hard part is not knowing the latest trends & where to get the reading material, specially notes from the local gurus ......

Heard there are shops in Delhi who makes copies of all notes, if anyone knows anything......

The principle of operation of an ILS localiser transmitter is based on two overlapping lobes that are transmitted on (i).......... frequencies and carry different (ii)..........


a. (i) different (ii) phases
b. (i) the same (ii) modulation frequencies
c. (i) the same (ii) phases
d. (i) different (ii) modulation frequencies

[Pulkdahulk]

I will change my answer

D i) different (ii) modulation frequencies
Different frequency as 90Hz and 150Hz so different modulation, although i think it could be phase comparision too but that would go with Glideslope. I would take D

If i got the Question right like it being transmitted from the localizer on for say 109.1 as i know i read in GSP that the actual transmission use a different frequency for each plane and modulates it at different frequency

DDM - difference in depth modulation

[sonsal]

guys you need to increase your level......you guys are not able to answer all these easy questions and asking all these in forums.....kindly study properly, that will answer your all the questions u asking here.
Remember its ATPL , not CPL.

[Pulkdahulk]

Ok according to GSP ILS Chapter Q5.

What ROD should an aircraft use on a 3.5 degree ILS GlideSlope if it has a GS of 120 Kts

1. 500 fpm
2. 600 fpm
3. 700 fpm
4. 800fpm

I tried the Oxford method and one more other method and I am getting 700 fpm but the answer is 600 fpm. Am I doing something wrong or is GSP wrong

[Aviator09]

I tired doing it too with two formulas but the answer remains same as 700 feet/min. I think stick with the answer coz there might be errors with answers in there. Let other people give clarifications regarding the answer if they can figure out how to get 600.
If the glide slope angle is 3 degree then answer comes out to be 600 feet/min. May be the answer's solved taking the standard 3 degree glide slope angle.

The principle of operation of an ILS localiser transmitter is based on two overlapping lobes that are transmitted on (i).......... frequencies and carry different (ii)..........


a. (i) different (ii) phases
b. (i) the same (ii) modulation frequencies
c. (i) the same (ii) phases
d. (i) different (ii) modulation frequencies

Answer is B
Same freqq means the one which you feed in your radio panel and DDM of 150hz and 90hz

tricky question plane boy.

@yash
in the answer that you posted for the distance btween two vors sum, what have u taken as the unknown variable x ive not really understood the explanation if you would care to elaborate it would be much appreciated. cheers mate

[planeboy_777]

Aviator09

1.6xground speedx(Theta)=ROD(fpm)


this is for any glide path angle (theta)

[Aviator09]

1.6xground speedx(Theta)=ROD(fpm)


this is for any glide path angle (theta)

@ Planeboy_777
For the question asked, can you further explain how to derive the answer using this formula.I've never come across this one.!

[planeboy_777]

5 X Ground speed = ROD(fpm)

that is only for 3 degree GS
but for different glide slope angle the formula is

5 x Groundspeed x [(theta)/3] = ROD(fpm)

i.e (5/3) x Groundspeed x Theta = ROD(fpm)

1.666 x theta(deg) x Groundspeed(kts) = ROD(fpm) [[[[[For any GPA]]]]]

just trying to Make it simple.....

[yash]

@ arsenal

x here is distance travelled .

i used :

degrees off track / 60 = dist off track / total distance travelled ( x in this case )
