A flight controller needs to calculate the total distance of two flights. The first flight covers 740 nautical miles and the second covers 3 times less the distance of the first flight. What is the total distance covered by both flights?

  • 1850 nautical miles

During an emergency, a controller gives directions to reroute a plane. If the controller uses terms unfamiliar to the pilot, what is the possible consequence?

  • The pilot may perform the correct maneuver more efficiently.
  • Miscommunication could lead to a delay in following the directions.
  • The pilot can ignore the directions without repercussions.
  • The use of unfamiliar terms is preferred during emergencies.

A radar system intermittently loses signal, potentially because several aircraft are simultaneously entering the zone. What is the best immediate action for the air traffic controller to take?

  • Ignore the signal loss as a minor technical glitch.
  • Instruct all flights to increase altitude to regain the signal.
  • Immediately switch to a backup system to maintain surveillance.
  • Request that all pilots confirm their positions via radio.

    Most of the questions I did not find challenging. The time factor of the work made it quite challenging because I had to think fast and come up with the correct answer. I had to plan ahead Incase I needed To do calculations.

    Quicker than usual

    I performed this test slightly faster than I usually would have. It would've been easier if numbers were listed. For example, on question 7. Although I understand reading graphs is likely part of the test

  • United States of America

    Have a calculator available before starting test

    A disclaimer before the test stating a calculator is required would be helpful. Difficult to calculate ratios in your head on a timed test.

  • Canada

    January 09, 2022

    Economics based questions

    I don't know if this is a great representation of what the actual test would be like? I think the math questions are supposed to be mental math without a calculator and I don't think that's possible for these.

  • United Kingdom

    December 27, 2021

    It's about maths, esp calculating percentages and ratios

    Questions could be clearer, particularly about which number we want our answer expressed as a percentage of.

    First test

    At first I didn't know what to expect, didn't even know what to do, but after a few minutes I understood the tasks and it went well. Didn't mange to finish in time, because I struggled at the start.

    Easy considering I took the practice test beforehand

    Thought the test was fairly difficult on the first attempt during practice but once I refreshed my memory on this math it was a lot easier.
