ATPL Performance practice questions

Performance (032) covers take-off, climb, cruise, descent and landing performance for single-engine, light twin and MRJT aeroplanes, along with the regulatory requirements behind them. Many questions use the graphs and tables in CAP 698.

About the exam

What to expect in 032 Performance

You need both the theory, such as how wind, slope, temperature and contamination affect field length, and fluency with the CAP 698 charts. Accuracy reading graphs is worth practising early.

In the practice desk you can sit a full 45-question paper under exam conditions, or drill one syllabus topic at a time. Questions you miss come back after 1, 3, 7, 16 and 35 days, so weak areas get repeated until they stick.

Sample ATPL Performance questions

Five questions from the bank. Each one in the practice desk has a worked explanation like these.

Sample 1 · 032 01 · General

Which aeroplane must be operated in performance Class A, according to the EASA operational rules?

  1. AA twin-engine turbojet aeroplane with a maximum take-off mass of 4 000 kg and 6 passenger seats
  2. BA single-engine turbopropeller aeroplane with a maximum take-off mass of 5 500 kg and 8 passenger seats
  3. CA twin-engine piston aeroplane with a maximum take-off mass of 4 500 kg and 6 passenger seats
  4. DA twin-engine turbopropeller aeroplane with a maximum take-off mass of 5 000 kg and 8 passenger seats
Show the answer

Answer: A. A twin-engine turbojet aeroplane with a maximum take-off mass of 4 000 kg and 6 passenger seats

Class A applies to all multi-engine turbojet aeroplanes, and to multi-engine turbopropeller aeroplanes with more than 9 passenger seats or a maximum take-off mass above 5 700 kg. Smaller multi-engine turbopropellers and piston aeroplanes are Class B.

Sample 2 · 032 02 · CS-23 / Performance Class B: Theory

The take-off ground roll of a light aeroplane is 400 m. Assuming constant thrust and ignoring changes in drag and ground friction, what is the approximate effect on the ground roll of a 10% increase in take-off mass?

  1. AAn increase of about 10%
  2. BAn increase of about 33%
  3. CAn increase of about 5%
  4. DAn increase of about 21%
Show the answer

Answer: D. An increase of about 21%

A greater mass lowers acceleration in proportion to the mass, and raises the liftoff speed in proportion to the square root of the mass. Because distance varies with V² divided by acceleration, the ground roll varies with the square of the mass: 1.10² = 1.21, an increase of about 21%.

Sample 3 · 032 04 · CS-25 / Performance Class A: Theory

What is the maximum crosswind component demonstrated for take-off and landing for MRJT1? Refer to CAP 698 Section 4, paragraph 1.1.4 in your own copy of the manual.

  1. A25 kt
  2. B38 kt
  3. C33 kt
  4. D17 kt
Show the answer

Answer: C. 33 kt

Section 4, paragraph 1.1.4: the demonstrated crosswind is 33 kt, related to a height of 10 m. The 17 kt figure belongs to SEP1 and MEP1.

Sample 4 · 032 05 · CS-25 / Performance Class A: Use of Aeroplane Performance Data

MRJT1 is landing with a wind of 40 kt at 70° to the runway. Is the crosswind within the demonstrated limit? Refer to CAP 698 Section 4, paragraph 1.1.4 and Figure 4.1 in your own copy of the manual.

  1. AYes, the limit only applies to take-off
  2. BYes, the demonstrated limit is 40 kt
  3. CNo, the limit is only exceeded by the headwind component
  4. DNo, the crosswind is about 38 kt, above the 33 kt limit
Show the answer

Answer: D. No, the crosswind is about 38 kt, above the 33 kt limit

Crosswind = 40 × sin 70° = 37.6 kt. The demonstrated maximum for MRJT1 is 33 kt (17 kt is the SEP1 and MEP1 figure).

Sample 5 · 032 02 · CS-23 / Performance Class B: Theory

For MEP1, the one-engine-inoperative net gradient of climb is the gross gradient decreased by: Refer to CAP 698 Section 3, paragraph 4.1 in your own copy of the manual.

  1. A2.5%
  2. B0.5%
  3. C0.8%
  4. D1.1%
Show the answer

Answer: B. 0.5%

Section 3, paragraph 4.1(b): the net gradient of climb is the gross gradient decreased by 0.5%.

Revision tips

How to revise Performance

  • Learn the theory questions as cause and effect: what increases or decreases each distance and why.
  • Practise CAP 698 graphs with a ruler and a sharp pencil. Small reading errors are the most common way to lose marks.
  • Know the regulatory factors and gradients for each class of aeroplane. They come up in both theory and chart questions.
