ashb,
Take a look online for PILAPT maths tests for CTC and there are a plethora of resources.. here are some examples (using a site CTC cadets recommended to me)
- What is 23 x 2453
- Calculate 5/3 divided by 2/9
- What is 405000 divided by 27000
- An aircraft descends to a new altitude of 4500 ft in a constant 500 ft/min descend rate. At which altitude did it commence the descend if the descend is completed in 11 minutes?
Make of that what you will, but the site in question has pretty good ratings.
Good luck :-)
