CAA-B Air Law common mistakes
CAA-B Air Law · Understand the traps and how to avoid them.
Applying VFR weather minima from memory without distinguishing between airspace classes or altitudes, such as using the same visibility and cloud clearance for all classes.
Candidates often memorize a single set of minima and fail to recognize that minima vary by class (e.g., Class C vs. Class G) and by altitude (e.g., below 900 ft AMSL vs. above).
What to do instead
Create a table of VFR minima by airspace class and altitude band, and practice applying them to scenarios. Always check the specific regulation for the class and altitude in question.
Confusing the privileges and limitations of different licence types (e.g., PPL vs. CPL) or the requirements for recent experience.
Candidates mix up the hours required for issuance, the privileges (e.g., carrying passengers for remuneration), and the recency rules (e.g., 90-day passenger carrying, 24-month biennial flight review).
What to do instead
Make a comparison chart of licence types, privileges, and recency requirements. Focus on the specific numbers and conditions for each.
Misinterpreting the rules for aerodrome traffic patterns, such as the direction of turns, altitude restrictions, and radio calls.
Candidates assume standard left-hand patterns apply everywhere and overlook specific aerodrome requirements or noise abatement procedures.
What to do instead
Study the standard traffic pattern rules and practice reading aerodrome charts (e.g., VAC) to identify pattern direction and altitude. Always verify the specific aerodrome's requirements.
Incorrectly applying the rules for carriage of documents, such as which documents must be on board and which can be kept elsewhere.
Candidates memorize a list without understanding the conditions (e.g., journey log may be kept at base, but aircraft documents like Certificate of Registration must be on board).
What to do instead
Categorize documents by where they must be kept (on board vs. at base) and the conditions. Use flashcards to reinforce.
Failing to correctly identify the classification of an occurrence (accident vs. incident) and the reporting requirements (e.g., immediate notification vs. written report).
Candidates confuse the definitions of accident and serious incident, and are unsure of timelines and to whom reports must be submitted.
What to do instead
Study the definitions and examples from the regulations. Create a flowchart for occurrence reporting, noting timelines and authorities.
Misapplying right-of-way rules, such as assuming the more maneuverable aircraft always gives way or misidentifying the least maneuverable category.
Candidates memorize a hierarchy but forget exceptions (e.g., an aircraft towing gliders has priority) and the specific distances (e.g., 500 ft from persons/structures).
What to do instead
Learn the right-of-way hierarchy with exceptions and practice with scenarios. Emphasize the 500 ft rule and its exceptions.
Incorrectly determining the validity period of a medical certificate based on age and licence type.
Candidates overlook that validity decreases with age (e.g., 12 months for under 40, 6 months for over 40 for certain licences) and varies by licence category.
What to do instead
Create a matrix of medical certificate validity by age and licence type. Review regularly.
Misunderstanding airspace classifications and their associated requirements, such as transponder or radio equipage, and VFR clearance requirements.
Candidates treat all controlled airspace similarly and forget that Class C requires a clearance for VFR, while Class D requires only radio contact, etc.
What to do instead
Study the differences between airspace classes (A-G) with regard to VFR/IFR, clearances, equipment, and services. Use a comparison table.
Overlooking the specific conditions for special VFR (SVFR) clearances, such as minimum visibility and cloud clearance, and the requirement for a clearance.
Candidates assume SVFR minima are the same as standard VFR or that SVFR is available in all airspace.
What to do instead
Memorize SVFR minima and conditions, noting differences by airspace and time of day. Practice with scenario-based questions.
Confusing the requirements for aircraft registration and airworthiness, such as the difference between a Certificate of Airworthiness and a Permit to Fly, and their validity.
Candidates mix up the documents and their purposes, and are unsure about continuing airworthiness requirements.
What to do instead
Create a summary of aircraft documents, their purpose, issuance, and validity. Focus on the differences between standard and special categories.
