032 Aeroplane Performance
General performance theory and performance-class B and A take-off, climb, cruise, approach and landing calculations.
How to prepare for UK CAA ATPL theory
Work from your ATO recommendation and selected A/H route, master the official learning objectives by subject code, then rehearse paper-specific timing, calculations and operational decisions.
Core concepts
Concept 1
Aeroplane performance depends on mass, configuration, pressure altitude, temperature, wind, runway condition and obstacle requirements.
Exam cue: Identify performance class, phase and limiting case before selecting data.
Concept 2
Performance Class B and Class A use different certification and operational concepts, including distinct take-off and engine-failure cases.
Exam cue: List every condition and correction before reading the chart.
Concept 3
Charts and tables must be entered, interpolated and corrected in the order and units specified by the source.
Exam cue: Compare required distance or gradient with the available or required standard using matching definitions.
Risk pitfalls and guardrails
Mixing accelerate-stop, accelerate-go and all-engines data.
Guardrail: Do not mix ATPL(A), ATPL(H) and ATPL(H)/IR paper requirements or treat the aggregate 601-item study allocation as an official CAA examination total.
Applying a headwind or runway correction in the wrong direction.
Guardrail: Do not mix ATPL(A), ATPL(H) and ATPL(H)/IR paper requirements or treat the aggregate 601-item study allocation as an official CAA examination total.
Using a chart beyond its stated range or skipping an interpolation.
Guardrail: Do not mix ATPL(A), ATPL(H) and ATPL(H)/IR paper requirements or treat the aggregate 601-item study allocation as an official CAA examination total.
Memory anchors
Performance Inputs
Mass, configuration, altitude, temperature, wind and surface condition drive the calculation.
Class B
Class B centres on smaller aeroplane performance with its own take-off, climb and landing requirements.
Class A
Class A uses decision-speed and engine-failure accountability across defined take-off segments.
Chart Discipline
Read title, axes, units, reference conditions and correction order before plotting.
Required versus Available
Compare like with like: required distance with the corresponding available declared distance.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
Short check-up to confirm understanding of this module.
