Aircraft specs are part of the test material document that you have to learn, so I am assuming they will be playing a part in it.

For anything that I am having to learn, such as the document I have been using a free program called Anki, which is basically electronic flash cards. Aswell as obviously just reading through the document itself.

There is also an app for the iPhone/iPod touch which allows you to sync all your cards. So I can do them on my iPod. (very handy on a lunch time at work)

For the maths, I have just been doing the usual OASC website practice, aswell as the guide on the student room forums ( dummies guide to speed, distance, time ) which has a lot of practice questions.

Also, to anyone who was at stage 3 with me today. What time did you leave? When I came out of my interview you were already being shown round the facility and I was told I could go.

Hi, this post is particularly destined, because of it's nature, to those who are going to attend stage 1. I found this PDF file which is a book for potentiall ATC explaining how to resolve math operations up to the required standards to pass the selection process. Personally, I think it's worth looking at. Hope it helps.

You have to sign up/in the forum to able to download the wretched file, bit of a nuisance but don't hesitate in doing so if you are weak on maths.

Hi Guys,

Got an email this morning saying I passed the online test

But they dont have any dates available yet for stage 1, so I'll get an email soon regarding this.

Loving this thread though guys, some of the practice material is really good and kudos to those guys who are sharing that info.

Good luck EVERYONE!

I'm starting to despair with the difficulty of the maths regarding stage 1. How hard are the problems?? I keep finding different types of S/D/T problems which I am not familiar with and all sorts of arduousness. Is anybody capable of telling me if, for instance, the problems copied below are more difficult than the ones in the real test or if easier??. Thankss loadss!, I'm in complete despair..

For this question let the distance travelled for each leg equal D. Let the time taken to get there be (t-1) and the time taken to get back as t (total time would be 2t-1).

The average speed of the trip is 220mph and the average speed on the way back is 200mph. From this info you can make two equations.

(1) D = 200t

(2) 2D = 220(2t-1)

(these were made using simple distance = speed * time)

Doubling (1) gives 2D = 400t to make equation (3)

You can now equate (2) and (3) so that:

400t = 220(2t-1) Expanding gives:

400t = 440t - 220 Re-arranging gives:

40t = 220 so t = 5.5

But you know that the total time for the trip is 2t-1 so:

(2*5.5)-1 = 10h

For questions like this you should write out everything you know about each AC, and what they have in common.

In this question the value they have in common is their distance which we will call D again.

AC A:

All we know is that AC A has been flying for five hours total at an average speed S, as B left 3 hours after and caught up after 2 hours. So all you can say is that:

D = 5xS

AC B

AC B has been flying for a total of two hours at a speed which is 42 mph faster than AC A.

D = 2(S+42)

These two can be equated (they both equal D) to give:

5S = 2(S+42) Expanding gives:

5S = 2S + 84 Re-arranging gives:

3S = 84

So the average speed is 28 mph

Plane B:

Plane B has allready travelled 400*2 = 800 miles

So its distance for any time after can be written as:

D = 800 + 400t (1)

Plane A

Plane A has travells at 600mph so its distance can be written as:

D = 600t

The qustion asks you to find the time at when place A is 400 miles behind B, so its distance will be 400 less (D-400) which means that:

D - 400 = 600t Re-arranged to give:

D = 400 + 600t Which can be equated to (1) to give:

800 + 400t = 400 + 600t re-arranged to give:

200t = 400

So t = 2 hours

The plane has allready been travelling for 2 hours so 2+2 = 4 hours .

Hope this helped, if I have made any mistakes others could point them out and lemme know if you have any other questions.

*A cargo plane flew to the manteinance facility and back. It took one hour less time to get there than it did to get back. The average speed on the trip was 220 mph. The average speed on the way back was 200 mph. How many hours did the trip there take? (SOL: 10 hours).*For this question let the distance travelled for each leg equal D. Let the time taken to get there be (t-1) and the time taken to get back as t (total time would be 2t-1).

The average speed of the trip is 220mph and the average speed on the way back is 200mph. From this info you can make two equations.

(1) D = 200t

(2) 2D = 220(2t-1)

400t = 220(2t-1) Expanding gives:

400t = 440t - 220 Re-arranging gives:

40t = 220 so t = 5.5

But you know that the total time for the trip is 2t-1 so:

(2*5.5)-1 = 10h

*Aircraft A left airport and flew south. Aircraft B left three hours later flying at 42mph faster in effort to catch up to A. After two hours B finally caught up. Find A's average speed. (SOL: 28mph)*For questions like this you should write out everything you know about each AC, and what they have in common.

In this question the value they have in common is their distance which we will call D again.

AC A:

All we know is that AC A has been flying for five hours total at an average speed S, as B left 3 hours after and caught up after 2 hours. So all you can say is that:

D = 5xS

AC B

AC B has been flying for a total of two hours at a speed which is 42 mph faster than AC A.

D = 2(S+42)

These two can be equated (they both equal D) to give:

5S = 2(S+42) Expanding gives:

5S = 2S + 84 Re-arranging gives:

3S = 84

So the average speed is 28 mph

*Plane B left Chicago flying due east at a speed of 400 mph. Plane A left Chicago 2 hours later, flying in the same direction at a speed of 600 mph. If plane A is 400 miles behind plane B now, how long has plane B traveled?*(SOL 4h)Plane B:

Plane B has allready travelled 400*2 = 800 miles

So its distance for any time after can be written as:

D = 800 + 400t (1)

Plane A

Plane A has travells at 600mph so its distance can be written as:

D = 600t

The qustion asks you to find the time at when place A is 400 miles behind B, so its distance will be 400 less (D-400) which means that:

D - 400 = 600t Re-arranged to give:

800 + 400t = 400 + 600t re-arranged to give:

200t = 400

So t = 2 hours

The plane has allready been travelling for 2 hours so 2+2 = 4 hours .

No I wasn't there yesterday, nobody could accomodate a visit for me before then so I have to wait until April 27th! It's more time to prepare and get some really good scenarios organised.

How did it all go yesterday then? Good luck with your results!!!! I hope you've been successful

KirtjE:

How did you find the stage 3 as well? I hope you achieve success too so good luck hearing back happy news!!!

@Rel17

Hi there.

Basically there are 5 rounds of 5 questions.

eacgh question gives you a sequence of letters/numbers which increases every question each round, and as each round goes on you get less time to answer the questions.

For example they will give you:

GTYRTY

and then 5 options which you have to match up to the original.

eg:

GTRYTX

GTYRTY

GTFRED

HGYTRG

GTYPRT

you will have either 5,6,7,8 or 9 seconds to pick the correct sequence.

@hatemyjob

The tour lasted for about 20 mins, we havent really seen a lot.

Let me know if you've passed stage 3!

@everyone

Don't stress too much about stage 1. The calculations are basic school stuff and really easy. Just take a look into the materials they provide to you and remember the basic stuff for stage 1.

**Help stage 1 :(**

Hey... anyone else taking the STAGE 1 test friday 8th April at 9:00 at Fareham?

I had a question... with the 25 Page booklet they gave us... how much of the exam will we actually be tested on it?

and with the abreviations of LACC , ISAO , SATC, will we need to memorize those?

and the difficulty of the math equations ???

i'm panickingggggggg

Can anyone tell me if the software and practices used by ATC in the UK is the same as America?

Im thinking way way far ahead but if someone wanted to move away to work as an ATC would they be able to?

I would imagine NATS hold you to the job but is that for a certain period or until you leave the job?

Any info at all would be fantastic.

Thanks

You can't work in the US as an ATCO unless you are a US citizen. Other countries often accept experienced ATCO's such as Australia, Canada and the Middle East although they use different systems and practices and require a seperate course to be taken once you are employed. You are not tied in to NATS for any length of time although most countries require 2-3 years experience minimum.

How do Guevarra, I would say in regards to the 25 page document learn as much as possible. Always better to have learnt too much, than not enough.

As for the maths, I can't answer your question unfortunately as I am still waiting to go for my Stage 1 also. The view I have taken on the maths, is concentrate on getting the basics as nailed on as you possibly can. As you will always use the same formula for any question.

I think for the Maths section, it's probably more a case of finding the way that works for you.

Good Luck for you Stage 1! That goes for everyone at Stage 1, 2 and especially 3
