RePL common mistakes
RePL · Understand the traps and how to avoid them.
When asked what a RePL allows, the candidate answers as if the licence alone authorises commercial operations, flight in controlled airspace, or flight beyond visual line of sight - ticking 'yes' whenever the question mentions a licensed pilot.
The licence and the operator certificate are taught side by side and both are abbreviated 'R...', so the student collapses them into one permission. Exam questions then get answered from the licence alone instead of from all three layers that must exist.
What to do instead
Draw a three-column card and re-derive it from the source rules: (1) person - RePL; (2) organisation - operator certificate; (3) task-specific approval - airspace, area, or operation type. Before answering any 'may I fly' question, name which of the three the question is actually about, and reject any option that grants a privilege from the licence alone.
Recites the operating limits as rounded, half-remembered numbers - 'about 100 m', '150 m ceiling', '5 km from an airport' - and cannot place the exceptions beside each limit.
The numbers are learned by repetition from sample questions rather than from the regulation, so they drift toward round figures and the conditions attached to each limit are never encoded.
What to do instead
Rebuild each limit from the current regulation and write it as a sentence with its exception: the 120 m (400 ft) AGL ceiling, the 30 m separation from people not directly associated with the operation, and the aerodrome/controlled-airspace approval requirement. Test yourself by writing the number, the unit, the reference point (AGL, not launch height), and the approval that would lift it.
Treats 'directly associated with the operation' as 'anyone who agreed to be there', and plans a flight over a consented crowd or a film crew's bystanders on that basis.
The phrase is read as consent rather than as a role test, and consent feels like it should settle the question.
What to do instead
Define the term as people required for the operation (crew, spotters, people being filmed by prior arrangement) and test each person in the plan against that definition. Anyone who is simply present and not needed for the task is not associated, and the separation requirement applies to them regardless of what they signed.
Answers performance questions using outside air temperature alone - 'it's only 28 °C, so performance is fine' - and never computes pressure or density altitude for a hot day at an elevated or low-pressure site.
Temperature is the only performance variable the candidate can feel, and density altitude is treated as an abstract formula rather than the thing that actually reduces lift, thrust and propeller efficiency.
What to do instead
For every performance question, run the chain explicitly: elevation → pressure altitude with QNH → density altitude with temperature → then take the performance figure from the density-altitude column. Practise three worked examples (sea level hot, 2000 ft mild, 3000 ft hot) until the chain is automatic.
Plans endurance from the manufacturer's advertised flight time, plans to use the whole pack, and is then surprised when the low-battery warning arrives early on a cold day with wind and a climb.
Advertised endurance is measured in ideal conditions at low payload, and the candidate has no mental model of voltage sag under load or of cold reducing usable capacity.
What to do instead
Plan on 70–80 % of the published figure and state a landing reserve as a percentage of pack capacity, not a time. In the plan, note the voltage under load at which the flight will be terminated, and treat a cold pack as a reduced-capacity pack, not as a normal one.
Reads a METAR as if it were a forecast, reads a TAF as if it were current conditions, and skips the TEMPO and BECMG groups entirely when deciding whether the flight can go ahead.
Both products use the same code groups, so the candidate decodes the weather correctly but attaches it to the wrong time - the harder skill of decoding is mastered while the simpler one of 'is this now or later' is not.
What to do instead
Before decoding a single group, label the product: METAR is an observation with an issue time for a specific hour; TAF is a forecast for a validity period. Then read trend groups as separate statements with their own timing, and ask 'does this affect my flight window?' for each one, not 'what is the weather today?'
Reads only the lateral boundary of an airspace on the chart - 'the circle covers the site, so it's controlled' or 'I'm outside the circle, so it's clear' - and ignores the lower and upper vertical limits and the class of the airspace.
The boundary lines are the visually dominant feature on the chart, and the vertical limits are printed in small numbers that the candidate has learned to look past.
What to do instead
Adopt a fixed reading order for every airspace volume: class, lateral limits, lower limit, upper limit, then controlling authority. Say it out loud in that order before judging the site, and cross-check the same volume in the current aeronautical information publication rather than from the chart alone.
In human-factors scenarios the candidate picks the most compliant-sounding option - usually 'abandon the flight' - instead of the option that actually addresses the pressure in the scenario, and cannot name the hazardous attitude being described.
Human factors is treated as general knowledge, so the answer is chosen for tone rather than by identifying the specific mechanism (get-there-itis, plan continuation, external pressure, complacency, resignation).
What to do instead
Answer in two steps: first name the attitude or bias the scenario is built around, then select the action that removes the source of pressure rather than one that merely sounds cautious. Practise by writing the name of the bias in the margin before looking at the options, and reject distractors that sound safe but leave the pressure in place.
Reads back only the part of a clearance they expected - the altitude but not the area, or the callsign but not the instruction - or replies 'roger' or 'copy' to a clearance that requires a full readback.
Readback is performed as a courtesy acknowledgement rather than as a verification loop, so the candidate transmits the portion already held in working memory and omits the new information that actually needs checking.
What to do instead
Use a fixed readback template - callsign, then every element of the clearance in the order given - and treat 'roger' and 'copy' as forbidden after any clearance, instruction or frequency change. If any element was not heard clearly, the readback is replaced by 'say again' rather than by a guess.
Produces a flight plan containing route, altitude and timings but no contingency content: no defined lost-link or fly-away action, no nominated emergency landing area, and no stated trigger for abandoning the task.
The plan is written as a description of the intended flight, so only the intended path gets documented; emergencies are assumed to be handled 'when they happen' with knowledge the pilot believes they already have.
What to do instead
Add a one-page emergency annex to every plan with four rows - lost link, fly-away, battery or power failure, and personal or airspace threat - each with a trigger, an immediate action, and a nominated landing area. Rehearse the triggers so that the decision is made before the flight, not during it.
