Numerical

Data Interpretation

Selection tests and the flight deck both demand quick, accurate reading of tables and figures. Scan a short dataset and answer totals, differences and which entry is highest or lowest, without losing time.

About this test

What this test measures

This measures reading and reasoning with tables and figures: pulling the right number from a busy dataset and combining values correctly. Charts and tables fill the performance and planning manuals, so fast, accurate extraction matters.

How to improve your score

Read the question first, then go to the table knowing exactly which cell you need.
Check the column and row headings and the units before you take a value.
Do the arithmetic on the extracted numbers carefully, the lookup is only half the task.

Good to know

Read the question before the table

Find out what is being asked, then look only for the figures you need. Absorbing the whole dataset first wastes time you do not have and tempts you into using the wrong row.

Totals, gaps and extremes

Almost every item is a sum, a difference, or a highest or lowest. Once you spot which, the answer is one or two clean operations away. Check you are comparing like with like, the same column and the same units.

Chart check: when the answer is Cannot tell

In Chart check mode the trap is a plausible statement the chart cannot actually settle: a claim about a category that is not plotted, a change over time when only one period is shown, or a per-unit rate when only totals are given. Those are Cannot tell, not False. Answer False only when the chart shows it is false.

Frequently asked questions

How do I read a table under time pressure?

Read the question first, then look only for the figures it needs. Do not absorb the whole table before you know what you are solving.

What is Chart check mode?

A second mode that mirrors the chart-verification format some real batteries use: one chart stays fixed while a stream of statements appears, and you mark each True, False or Cannot tell. The catch is Cannot tell: if the chart does not hold the answer, that is the right call, not False. The Hard preset paces it at 37 statements in 12 minutes.

Why is this a pilot skill?

Performance tables, fuel logs and load sheets are dense with numbers; pulling the right figure quickly and correctly is a daily task.

Are the numbers realistic?

They use aviation contexts such as fuel per leg, passengers per flight and distance per sector, with clean values so the focus is on reading, not long division.
