Airborne Numerical Test (ANT)

The ANT presents speed, distance and time problems, requiring you to locate the relevant values across two data sources and calculate an answer within one minute per question, including reading time.

Each question opens with a mission brief describing the task, for example finding the arrival time for a route across three named checkpoints. Read this first. It tells you what you are solving for, which determines which values you need and in what order to use them.

The display interface is divided into 3 areas: a menu panel on the left, a map on the right and the solving table under the Map.

Speed

Speed values need to be converted after tallying the provided information with either the the “Speed and Fuel Consumption“ or "Speed & Parcel Weight" sections in the left-hand menu. The values are displayed as a bar graph, with each leg or waypoint assigned a figure. Similar to reading a simple column chart, you match the checkpoint label to its bar height to get the value. When a route crosses multiple legs, check whether speed changes between them before calculating.

Top Tip: Round each speed value to the nearest clean number before starting; the test awards partial credit for close answers, so the time saved on cleaner arithmetic is worth the small rounding error.

Distance

Distance is read from the map on the right of the display. The map shows the route between named checkpoints with distances marked. If bad weather appears between two checkpoints, you reduce or increase the speed for that leg by a specific percentage. rather than the distance.

Time

With speed and distance in hand, divide distance by speed to get travel time, then add that figure to the departure time to find arrival.

If the question asks for the latest departure time instead, subtract travel time from the given arrival time.

Some questions ask only for the travel time between two specific points within a longer route (not the full journey end to end), so confirm what the question is actually asking before you calculate.

The ANT can be practiced in a format that mirrors the actual test. Air Defence Academy's CBAT/MACTs course includes a dedicated ANT module, with a simplified free version on the site — a useful first run to assess calculation speed and accuracy before committing to the full course.
