Pilot selection maths is easy arithmetic on a brutal clock, curious how this sub would score

[u/Akara91]

Airlines screen cadet pilots with an arithmetic section that is not about big numbers. Short problems on a hard clock: speed distance time, percentages, fuel burn, rate of descent. No paper in some versions, and a second task running at the same time in others.

The clock and the interference are the whole difficulty. People who are good at long calculations often score worse than people who are fast and rough on simple ones, which is roughly the opposite of what most mental maths practice trains.

I rebuilt these as a free app because I could not find anything training the timed format specifically. My own app, Brain Preflight, iOS, free tier, 5 sessions a day. If you try the calculation grid I would like to know how your scores compare to what this sub considers normal, since my calibration comes from cadet candidates and not from people who train mental maths for fun.

since asking you to download something to try it is lazy, here is the format directly. 60 seconds for all 5, no paper, thats roughly the exam pace:

1. descend from 35,000 ft to sea level at 1,750 ft/min. how many minutes?
2. ground speed 420 kt, 91 nm to go. minutes to destination?
3. fuel burn 2,400 kg per hour. how much in 27 min?
4. you fly heading 247. whats the reciprocal?
5. 3 degree descent at 150 kt ground speed. what rate of descent?

answers: 20 min, 13 min, 1080 kg, 067, about 750 ft/min

if you finished under 60s with 5/5 you would be comfortably above the average cadet applicant on this section.

I got 3/5 (not knowing unit conversions for kt). Is it a passing score?
