Slightly off topic because the bottom line is as PP says
"Whether it is crap or not at selecting pilot employees is a different question. Just remember that the airlines are happy with the ones who DO pass the filtering process and hence they offer them jobs. Nobody is saying that you have to agree with the testing regime."
However would not a better way of testing a pilot candidates basic maths involve questions applying those basic skills in questions relevant to pilots, for example
Q1) given you wish to achieve a 3 degree descent where for every mile a a 300 foot decent is requiered and to slow down by 10 kts requires 1 mile.
You are at 20000 ft and 280 kts. If you wish to reach your platform height of 3000 feet at 180 kts how many track miles do you require?
Q2)you have 12000 kgs of fuel on board.and your burn is 1500 kgs an hour, your ground speed is 300 kts how much fuel will you have over your destination 250 miles away?
Surely questions such as the above would be a better guide to who is a suitable candidate, rather than the current trend of contracting in an outside HR department.
