ATPL Performance (EASA) study plan
ATPL Performance · Give each week a clear focus.
8 weeks · About 7 hours per week
Take-off
Define the take-off distance components (TORA, TODA, ASDA, TORA clearway/stopway relationships) and state which declared distance each performance limit is compared against
Compute corrected take-off distances for pressure altitude, temperature, wind, slope, and runway surface using a worked example with a provided table of corrections
Distinguish field-length-limited from obstacle-limited take-off mass and explain how each is found on a take-off chart
Identify the certification basis differences between CS/FAR 25 large aeroplane take-off performance and light aeroplane performance data
Your checkpoint
A one-page worked solution set: three take-off mass problems (field-length limited, obstacle limited, and one combined) with all corrections shown and the limiting case stated
Take-off
Explain V1 definition, the decision-speed concept, and how V1 is selected between VMCG and VR constraints
Describe VMCG, VMCA, VMU, VR and V2 and state the speed-ordering rule VMCG <= V1 <= VR <= V2
Calculate the effect of a wet or contaminated runway on V1 and required take-off distance, including the 15 percent rule for wet runways where applicable
Interpret take-off performance for a derated or assumed-temperature thrust setting and state why it improves engine life without changing the limit mass
Your checkpoint
A written summary of at least 25 word-equivalents per item covering the five V-speeds, with a diagram-free explanation of what limits each one and one numeric V1 selection example
Take-off & Climb
Solve a full take-off chart problem including wind component calculation from runway heading and reported wind
Apply the obstacle-clearance requirement for the net take-off flight path and state the 35 ft screen height requirement
Define the segments of the take-off flight path (first, second, third, final) and the thrust and flap configuration in each
State the climb gradient requirements for two-engine and four-engine aeroplanes in the second segment and explain the origin of the 1.6 percent and 2.7 percent figures
Your checkpoint
A timed 10-question self-test on take-off and second-segment climb, scored and with every wrong answer corrected in writing
Climb
Compute climb gradient from rate of climb and ground speed, and convert between gradient and angle of climb
Explain the forces in a steady climb and how excess thrust, not excess power alone, sets the climb angle
Differentiate best angle of climb (VX) from best rate of climb (VY) and state how each shifts with altitude, wind, and mass
Interpret a climb performance chart to find time, fuel, and distance to climb for a given altitude change
Your checkpoint
A climb conversion worksheet with five gradient/rate conversions and one full time-fuel-distance to climb calculation, checked against a second method
Climb & Cruise and en-route
State the en-route climb requirements for the net take-off flight path and the obstacle clearance during the third and final segments
Explain driftdown and how the net flight path in the en-route configuration is used to clear terrain after an engine failure
Solve a cruise performance problem using a cruise chart to find fuel flow, TAS, and specific range for a given mass and level
Describe the effect of altitude, temperature, mass, and wind on specific range and state the conditions for maximum range cruise versus long-range cruise
Your checkpoint
A one-page driftdown and cruise comparison: two cruise levels compared on specific range and time, with the driftdown net flight path sketched in words and the limiting obstacle identified
Cruise and en-route
Calculate point of no return (equal time point) and critical point for a given route and wind, showing the formulas used
Explain the fuel policy structure (taxi, trip, contingency, alternate, final reserve, additional) and compute a minimum fuel figure for a sample flight
Interpret the effect of wind on still-air range, and compute the equivalent still-air distance for a sector with headwind and tailwind
State the requirement for en-route alternate selection and the 60-minute and 120-minute ETOPS-style diversion rules at a conceptual level
Your checkpoint
A complete flight fuel plan for a 500 nm sector with wind, contingency, alternate, and final reserve, plus the equal-time point calculation for the same route
Landing
Define LDA, the landing distance required, and the 1.67 factor (or 1.43 for turboprops where applicable) and state when each applies
Compute landing distance corrections for pressure altitude, temperature, wind, slope, and runway condition (dry, wet, contaminated)
Explain the approach climb requirement (2.1 percent for two-engine, 3.1 percent for four-engine) and the landing climb requirement (3.3 percent)
State the go-around decision and the landing mass limit imposed by climb and by field length, and identify which is limiting in a given case
Your checkpoint
A landing performance problem set of four cases (dry, wet, contaminated, and high-altitude) with the limiting factor named in each and the required LDA compared to available LDA
Take-off & Climb & Cruise and en-route & Landing
Complete a full-length timed mock under exam conditions and record the score by domain
Re-derive from memory the key formulas: gradient-rate conversion, equal-time point, landing distance factor, and take-off distance corrections
Review every mock question answered incorrectly and classify the error as knowledge gap, chart-reading error, or unit/conversion slip
Build a final one-page formula and limits sheet covering all four domains for last-day revision
Your checkpoint
A scored mock result with a domain breakdown and a completed one-page formula sheet, plus a written list of the three weakest sub-topics with a revision action for each
Milestones
Week 2: Can state all take-off V-speeds and their ordering, and correctly solve a take-off mass problem with wind, slope, and temperature corrections without referring to notes
Week 4: Scores at least 70 percent on the timed take-off and climb self-test, with no uncorrected errors remaining
Week 6: Produces a fuel plan and equal-time point calculation that reconcile to within 2 percent when reworked by a second method
Week 8: Achieves at least 75 percent on the full-length mock with no domain below 60 percent, and has a completed formula sheet and error log
