ATC Issues A place where pilots may enter the 'lions den' that is Air Traffic Control in complete safety and find out the answers to all those obscure topics which you always wanted to know the answer to but were afraid to ask.

I didn't know we can use calculator on Stage 1? Can we?

Negative. We can not.
You have to train your brain to be as fast as possible (in case you need it...maybe you are already good doing fast calculations in you head).

Good luck!

You cannot use a calculator at Stage 1.

Like Pat42 said, practise expressing times as fractions of 60. In fact practise fractions in general. It will help a lot!

Numerical Reasoning:

Dear Izach1,

This is Kingsley, the author of message/post 5748.

I deliberately asked the question like that, to catch people out.

(1) A/C flying at 18 miles per hour, hour long did it take to reach 140 miles ?

A. 7 hours and 8 mins

B. 7 hours and 7 mins

C. 7 hours and 48 mins

D. 7 hours and 42 mins

Solution: time = distance/speed. 140/18 = 7.8 hours ( approximately).

Now, this is the trick. Your 7.8 is in hours. So there is a fraction of an hour in your answer.
To convert that fraction into minutes multiply by 60. therefore (0.8 * 60) = 48 minutes.

Try this Simple Exercise:

Convert: 4.9 hours into hours and minutes
Ans = 4 hours and (0.9 * 60) 54 minutes
4 hours and 54 minutes.

Convert: 6.7 hours into hours and minutes
Ans = 6 hours and (0.7 * 60) 42 minutes
6 hours and 42 minutes.

Convert: 7.5 hours into hours and minutes
Ans = 7 hours and (0.5 * 60) 30 minutes
7 hours and 30 minutes.

Convert: 7.7 minutes into hours
Ans = divide 7.7 by 60 = 0.13 hours.

Convert: 10 minutes into hours
Ans = divide 10 by 60 = 0.17 hours.

If you want more examples on (numerical and Spatial) and solutions, my email is [email protected]

atc courses

Hi, fairly new on here so not sure if already been discussed, i have been into the MAN tower today and have always been fascinated by ATC, i currently work on MAN ramp as a tug driver so am always in communication with ground controller but have always wanted to be the guy giving the orders as to where to go etc, the only thing that frightens me about applying for a job with NATS is i'm not very good with maths and it takes me a long time to work things out, i am great on the RT so i have been told and know all the lingo, but also have a great understanding of how procedures work, any advice would be greatly appreciated as i would love to be a ground controller,

You need to be a good air controller as well!
Seriously, dont be put off by the job you do now - my experience is that good controllers come from very different backgrounds.
Good luck!

Numerical test preparation Guide Stage 1.

Hi Gays,
if you are preparing for the numerical test for the stage one selection day, take a look at this question.

(1) What speed covers 30 miles for 50 minutes ?

Solution:
Given that you are not allowed calculator during the test how do you calculate the answer to the above question within 20 seconds?

This is how you do it.

speed = distance/ time = 30 divide by 50/60 (convert mins to hours)
now, by the time you divide 50 by 60 and then use the result to divide 30, you have spent a significant amount of time.

but if you do it like this, 30 * 60/50 you have eliminated decimals, and you see that it will be faster to divide 30 by 5 and multiply the result by 6
ans = 36 miles per hour.

N.B

If you want to divide a number by a fraction, you can multiply that number by the inverse of the fraction as shown above.

Hi guys,
I have been following the thread though may of missed a post on these, what are peoples thoughts on the online (SHL) tests you have to do before attending stand 1 and does anyone know what implications your scores on these have. Do they effect what happens at stage 1, say if you didn't do particularly well you wouldn't want to get up there and they turn you away so to speak?

Hi All,

I've got my Stage 1 coming up soon. I've read almost all the posts on here.

I know no calculators are obviously used in the numeracy tests but is scrap paper allowed for working out?

Also having difficulty doing the following calculations in my head, basically trying to work out the logical way of doing it.

1. At 15mph, how long does it take to travel 14 miles?

2. At 35mph, how long does it take to travel 21 miles?

Answers appreciated with the working out.

Thanks

1. 15mph = 1 mile every 4 minutes, so to travel 14 miles would be 14 x 4 or 56 minutes

2. Find a number that 21 and 35 are both divisible by - in this case 7. 3 x 7 = 21 and 5 x 7 = 35. So to travel 21 miles at 35mph would take 3/5th of an hour so 36 minutes

Quick fix

Dear Q503,

No calculator nor scrap paper is allowed in you motivation test which include some numerical questions.

You are allowed scrap paper for your numerical test but no calculator. These are two different tests.

1. At 15mph, how long does it take to travel 14 miles?2. At 35mph, how long does it take to travel 21 miles?

Solution 1

Time = distance /speed. = (14/15) hour.
To convert hour into minutes multiply by 60.

Hence your solution will be (14/15) * 60 = 14 * 4 = 56 minutes.
By bringing 60 into the equation makes it easy and faster to calculate.

Solution 1

Time = distance /speed. = (21/35) hour.
To convert hour into minutes multiply by 60.

Hence your solution will be (21/35) * 60 = 3 * 12 = 36 minutes.

Divide 21 by 7 = 3 and 35/7 = 5 , use that 5 to divide 60 = 12
So it follows that 3 * 12 = 36 minutes.

Hi K_showme

1. At 15mph, how long does it take to travel 14 miles?

I'm not able to do 14/15 in my head, so I divided 15 by 3 = 20
then divided 20 by 5 = 4

meaning 1 mile = 4 mins
then 4 multiply 14 =56 mins

But this just seems like a long winded calculation, where am I going wrong???
